Menu 11 − Miscellaneous

Mode: RFC‑A

This menu provides the set up parameters for a number of drive functions. The table below covers some of the main functions controlled by this menu.

Option Synchronisation Select (11.001) is used to select and enable timing synchronisation between the communications system associated with an option module fitted to the drive and the drive control system. If  "Not Active" is selected then the drive control system operates using it's own processor crystal for control sample timing. If one of the option modules is selected and is making a request to provide synchronisation then the drive control sample timing will be synchronised to the communication system. Option synchronisation Active (11.002) shows the synchronisation source, where "Not Active" indicates that the drive is providing the timing for the control system. Any other value indicates if an option module is providing synchronisation. If required the synchronisation source can be selected automatically by setting Option Synchronisation Select (11.001) to "Automatic". In this case the option module in the lowest numbered slot that is making a request to provide synchronisation will be selected.

See Option Synchronisation Select (11.001).

See Parameter Displayed At Power-up (11.022).

If the set-up parameters for a serial communications port on the drive are changed via that port then if the parameter change took effect immediately it would disturb the communications. To prevent this any change to a serial port set-up parameter (as listed below) does not affect the communications set-up except at drive power-up and when this parameter (Reset Serial Communications (11.020)) is set to one. This parameter will automatically reset to zero. Therefore, the set-up parameters should be changed and when the communications exchange is complete, this parameter should be set to one. As this parameter causes the set-up parameters for both the keypad port and user 485 serial port (if present) to take effect it will disturb the communication on both ports if any of the set-up parameters have changed. If none of the set-up parameters for a particular port have changed then setting this parameter to one will not affect the communications of that port. The following is list of parameters that do not have an effect until this parameter is set to one.

User 485 Serial Port (if present)
Serial Address (11.023)
Serial Mode (11.024)
Serial Baud Rate (11.025)
Minimum Comms Transmit Delay (11.026)
Silent Period (11.027) 

Keypad Port
Keypad Port Serial Address (11.090)

Parameter 00.030 Scaling (11.021) defines the scaling applied to parameter 00.030 when it is displayed on a basic keypad. The scaling is only applied in the status and view modes. If the parameter is edited via the keypad it reverts to its unscaled value during editing.

If Status Mode Parameter 1 (11.018) and Status Mode Parameter 2 (11.019) are set to zero, then  Parameter Displayed At Power-up (11.022) defines which Menu 0 parameter is initially displayed at power-up. If Status Mode Parameter 1 (11.018) or Status Mode Parameter 2 (11.019) are set to valid parameter numbers, then Parameter Displayed At Power-up (11.022) defines the active parameter at power-up, i.e. the parameter first displayed when going in to parameter view mode on the keypad. Status Mode Parameter 1 (11.018) and Status Mode Parameter 2 (11.019) define the parameter values to be displayed on the upper and lower rows of the keypad respectively, when in status mode. If only one of these parameters is set correctly the other row will display the value of the current active parameter. If both Status Mode Parameter 1 (11.018) and Status Mode Parameter 2 (11.019) are set to the same parameter number then the parameter value is displayed as double height characters.

Serial Address (11.023) defines the node address for the user 485 serial comms interface in the range from 1 to 247.

Changing the parameters does not immediately change the serial communications settings. See Reset Serial Communications (11.020) for more details.

The core drive always uses the Modbus RTU protocol and is always a slave. Serial Mode (11.024) defines the data format used by the user serial 485 comms interface. The bits in the value of Serial Mode (11.024) define the data format as follows. Bit 3 is always 0 in the core product as 8 data bits are required for Modbus RTU. The parameter value can be extended in derivative products which provide alternative communications protocols if required.

Bit 2 selects either standard or modified register mode. The menu and parameter numbers are derived for each mode as given in the table below. Standard mode is compatible with Unidrive SP. Modified mode is provided to allow register numbers up to 255 to be addressed. If any menus with numbers above 63 should contain more than 99 parameters, then these parameters cannot be accessed via Modbus RTU.

Changing the parameters does not immediately change the serial communications settings. See Reset Serial Communications (11.020) for more details.

Serial Baud Rate (11.025) defines the baud rate used by the user 485 serial comms interface.

Changing the parameters does not immediately change the serial communications settings. See Reset Serial Communications (11.020) for more details.

Minimum Comms Transmit Delay (11.026) is used to define the time between receiving a request via the user 485 serial comms interface and the response to the request. The diagram below shows the timing with Minimum Comms Transmit Delay (11.026) set to 1 or more and with Minimum Comms Transmit Delay (11.026) set to zero.

Changing the parameters does not immediately change the serial communications settings. See Reset Serial Communications (11.020) for more details.

The silent period defines the idle time required to detect the end of a received data message on the user 485 serial port. If Silent Period (11.027) = 0 then the silent period is at least 3.5 characters at the selected baud rate. This is the standard silent period for Modbus RTU If Silent Period (11.027) is non-zero it defines the minimum silent period in milliseconds.

Changing the parameters does not immediately change the serial communications settings. See Reset Serial Communications (11.020) for more details.

Drive Derivative (11.028) shows the derivative identifier.

Software Version (11.029) displays the drive software version number as a decimal number wwxxyyzz. A keypad will display the value in this parameter as ww.xx.yy.zz.

See User Security Status (11.044).

User Drive Mode (11.031) is set to the current drive mode at power-up. The user can change the drive mode as follows:

1. Set Parameter mm.000 (mm.000) to 1253, 1254, 1255 or 1256
2. Change User Drive Mode (11.031) to the required mode
3. Initiate a drive reset

Provided Drive Active (10.002) = 0 the drive will change to the new drive mode, and then load and save parameters to non-volatile memory. If Parameter mm.000 (mm.000) is not set to one of the specified values then the drive mode does not change on drive reset. The value in Parameter mm.000 (mm.000) determines which defaults are loaded as follows.

Maximum Heavy Duty Rating (11.032), Minimum No-overload Current (11.059) and Maximum Rated Current (11.060) define the boundaries of different drive operating regions as shown in the table below. Rated current is defined by Rated Current (05.007) if Select Motor 2 Parameters (11.045) = 0 or if Select Motor 2 Parameters (11.045) = 1.

Not all the modes described are available in all drive sizes, for example if Maximum Heavy Duty Rating (11.032) = 0.000A then the drive can only operate in normal duty mode, or if Minimum No-overload Current (11.059) = Maximum Rated Current (11.060) then the no-overload region does not exist.

Drive Rated Voltage (11.033) shows the voltage rating of the drive.

For legacy applications Software Sub-version (11.034) shows the yy part of Software Version (11.029).

Number Of Power Modules Detected (11.071) shows the number of power modules detected in the drive when communications with the power system is established. The number of modules can be checked and a trip initiated depending on the value of Number Of Power Modules Test (11.035) as follows:

If Number Of Power Modules Test (11.035) = -1 a test is being carried out to see if the number of modules detected has changed. Number Of Power Modules Detected (11.071) is a user save parameter, and so on  power-up the number of modules can be compared with the number last saved when the system last powered up correctly.

If Number Of Power Modules Test (11.035) > 0 the expected number of modules are stored in Number Of Power Modules Test (11.035), and if the number powering up successfully changes then this can be detected.

The sub-trip number always indicates the expected number of power modules. The actual number detected can always be seen in Number Of Power Modules Detected (11.071).

NV Media Card File Previously Loaded (11.036) shows the number of the last parameter file transferred from an NV Media Card to the drive. If defaults are subsequently reloaded NV Media Card File Previously Loaded (11.036) is set to 0.

NV Media Card File Number (11.037) is used to select a file by its file identification number. This parameter can be set to any value between 0 and 999. If the value corresponds to the number of a file that is present on a media card inserted in the drive, then the file type and the file version number are displayed in NV Media Card File Type (11.038) and NV Media Card File Version (11.039) respectively. If any action is taken that opens a file on the card for writing or a file is deleted, then NV Media Card File Number (11.037) is reset to zero. These actions can be initiated via parameter mm.000, comms, or parameter save when auto mode is active. It should be noted that a parameter save is initiated for one parameter when a parameter is changed in Menu 0 by the keypad. This parameter is also reset to zero if no card is present or a card is removed.

NV Media Card File Type (11.038) shows the file type of the file selected with NV Media Card File Number (11.037).

A value of User Prog (5) is used when the drive cannot determine if the file is a parameter difference or macro file and it is assumed it is a drive onboard user program file. It is possible to store option module user programs on a media card via parameter mm.000. These files will also be shown with a value of 5. 

NV Media Card File Version (11.039) shows the version number stored in the file selected with NV Media Card File Number (11.037). A file version number can be set in a parameter difference or macro file using NV Media Card File Required Version (11.077) when the file is saved. If no version number has been set or the file is not recognised as a parameter difference or macro file the value is shown as zero.

This is a customer specific identification parameter.

If NV Media Card Disable Booting (11.041) = 1 the drive will not boot from a media card even if a bootable card is inserted into the drive. If this parameter is stored on a media card in a bootable file with a value of 1, then if the card is present in a drive with NV Media Card Disable Booting (11.041) = 0 (default value) at power-up, then the parameters will only be transferred from the card once. After the transfer NV Media Card Disable Booting (11.041) = 1 and parameters are saved. After the power is cycled the parameters will not be transferred to the drive again even if the media card is left in the drive.

Note: Only a value of 0 or 3 in this parameter is saved.

Parameter Cloning (11.042) can be used to initiate data transfer to or from an NV media card as described below. The required action is only initiated if the parameter value has been changed before a drive reset is initiated. This ensures that if Auto or Boot mode are selected that a write is not performed to the card on every drive reset. If Read (1) or Program (2) are successful this parameter is reset to zero, but if Auto (3) or Boot (4) are successful in creating File 001 then this parameter is not reset to zero so that the drive remains in Auto or Boot mode. If any of these actions are not successful then this parameter is not modified, and must be modified by the user before another attempt is made to initiate the required action. 

1: Read
If a parameter difference file with file identification number 1 exists on the NV media card then setting this parameter to 1 and initiating a drive reset transfers the parameter data to the drive (i.e. the same action as writing 6001 to Parameter mm.000 (mm.000)). When the action is complete this parameter is automatically reset to zero.

2: Program
Setting this parameter to 2 and initiating a drive reset transfers the parameter data from the drive to a parameter difference file with file identification number 1. This is the same action as writing 3001 to Parameter mm.000 (mm.000). When the action is complete this parameter is automatically reset to zero.

3: Auto
Setting this parameter to 3 and initiating a drive reset performs the same action as Program (2) and selects automatic back-up mode. See File System, SD and SMART Card document for more details.

4: Boot
The action is the same as Auto (3) except the file saved to the card is "bootable". See File System, SD and SMART Card document for more details.

If Load Defaults (11.043) is non-zero and a drive reset is initiated then the drive will load and save default parameters. If Load Defaults (11.043) = 1 then 50Hz defaults are loaded and if Load Defaults (11.043) = 2 then 60Hz defaults are loaded. This parameter has priority over actions defined by Parameter mm.000 (mm.000) and Parameter Cloning (11.042). If Load Defaults (11.043) is used to initiate loading defaults the it is cleared along with Parameter mm.000 (mm.000) and Parameter Cloning (11.042) when the action is completed.

Security

The drive provides a number of different levels of security that can be set by the user via User Security Status (11.044).

When security has been set up the drive can either be in the locked or unlocked state. In the locked state the security level that has been set up applies. In the unlocked state the security is not active, but when the drive is powered down and powered up again the drive will be in the locked state. The drive may be relocked without powering down by selecting the required security level with the User Security Status (11.044) and initiating a drive reset.

Security can be set up as follows:

1. The User Security Code (11.030) should be set to the desired security unlock code (not zero). For security to remain set after power down then a parameter save should be performed to retain the set value.
2. If no further action is taken when the drive is powered down and then powered up read-only security will be set up and locked.
3. If at any time the User Security Status (11.044) is set to a value corresponding to one of the security levels shown in the table above and a drive reset is performed, the security level is changed to that level. The desired security level is automatically saved and retained after power down, the keypad state changes to status mode and security is locked. (The security level that is active, provided User Security Code (11.030) has been saved as a non-zero value, is shown in Security Status (11.085).)

When security is set up and locked:

1. Parameter access is restricted as shown in the table above.
2. User Security Code (11.030) reads as zero except in parameter edit mode. Therefore it is not possible to read the value of the security code when any level of security is active and locked.

Security can be unlocked as follows:

1. If read-only security is set and locked then any attempt to edit any read/write parameter causes "Security code" to be displayed on the first row of the display. When the Up or Down keys are pressed the second row shows the code being adjusted. On setting the code the user presses the Enter key. If the correct code has been entered then the drive switches to Parameter edit mode on the parameter the user selected to edit, but if the correct code has not been entered the notification "Incorrect security code" is displayed for 2s and the drive returns to Parameter view mode.
2. If Status only or No access security is set and locked then any attempt to leave status mode causes the security code to be requested as per the process described above. The security code entered must be correct for the keypad state machine to switch to the Parameter view mode. It is then possible to access all parameters normally.

Security can be cleared as follows:

1. Security must be unlocked.
2. The User Security Code (11.030) should be set to zero. For security to remain cleared after power down then a parameter save should be performed.

At any time User Security Status (11.044) can be changed between 0 and 1 to restrict access to Menu 0 alone or to all menus. If the change is made by a keypad the new value becomes active on leaving parameter edit mode. It should be noted that User Security Status (11.044) is a volatile parameter and that the actual state of the security system is stored in Security Status (11.085) and Menu Access Status (11.086), which are both power-down save parameters. Therefore the security status will be stored when the drive goes into the under-voltage state. If the drive is already in the under-voltage state the security state should be saved by writing 1001 to Parameter mm.000 (mm.000) and initiating a reset.

Select Motor 2 Parameters (11.045) is used to select the motor map 2 parameters from Menu 21 to be substituted for the standard motor parameters. If Select Motor 2 Parameters (11.045) is modified when Drive Active (10.002) = 1 the change only becomes effective when Drive Active (10.002) = 0. When Select Motor 2 Parameters (11.045) = 1 the results from auto-tuning are written to the motor map 2 parameters in Menu 21 instead of being written to the standard parameters. Each time Select Motor 2 Parameters (11.045) is changed Motor Protection Accumulator (04.019) is reset to zero. Select Motor 2 Parameters (11.045) operates in the same way in Regen mode, but Inductor Protection Accumulator (04.019) is reset to zero each time the value is changed. Motor 2 Active (21.015) shows the motor map that is active.

Defaults Previously Loaded (11.046) shows the value used to load the previously loaded defaults (i.e. 1233 for 50Hz defaults, or 1244 for 60Hz defaults).

Onboard user programming provided a background task that loops continuously and a timed task that is executed each time at a defined rate. Onboard User Program: Enable (11.047) allows the onboard user program to be controlled as follows:.

-1: Reset And Run
The onboard user program will run. If Onboard User Program: Enable (11.047) is changed from 0 (Stop) to -1 (Reset And Run) all variables will be reset to their initial values and the user program will run from the start.

0: Stop
The onboard user program is stopped.

1: Run
The onboard user program will run. If Onboard User Program: Enable (11.047) is changed from 0 (Stop) to 1 (Run) all variables will be unchanged and the user program will run from the start.

The effect of the above is as follows:

• If the drive powers up with Onboard User Program: Enable (11.047) set to either 1 or -1 then all variables will be reset to their initial values before the user program starts.
• If the drive powers up with Onboard User Program: Enable (11.047) set to 0, and then Onboard User Program: Enable (11.047) is changed to either 1 or -1 then all variables will be reset to their initial values before the user program starts.
• If Onboard User Program: Enable (11.047) is set to 0 and then to -1 then all variables will be reset to their initial values before the user program starts.
• If Onboard User Program: Enable (11.047) is set to 0 and then to 1 then all variables will be left at their previous values before the user program starts.

Onboard User Program: Status (11.048) shows the status of the onboard user program. 

Onboard User Program: Programming Events (11.049) = 0 when the drive is manufactured and is incremented each time an onboard user program image is written to the drive. If an onboard user program image is written more than 65535 times Onboard User Program: Programming Events (11.049) = 65535. Onboard User Program: Programming Events (11.049) shows how many times the flash memory within the drive has been reprogrammed.

During each scan in a freewheeling task it is possible to give an indication to the drive that the scan loop is starting. If this indication is given then Onboard User Program: Freewheeling Tasks Per Second (11.050) will give the number of times this indication is given per second. It should be noted that this parameter is updated once per second. Because the background time slot for the user program background task occurs every 64ms (15.625 times per second) either 15 or 16 time slots could have been allocated over the montoring period. Therefore the value given by this parameter can step between two values, one corresponding to the number of updates for 15 slots, and the one corresponding to the number of updates for 16 slots.

Onboard User Program: Clock Task Time Used (11.051) shows the percentage of the available time used by the onboard user program clock task.

The drive serial number is available as a pair of 32 bit values where Serial Number LS (11.052) provides the least significant 9 decimal digits and Serial Number MS (11.053) provides the most significant 9 decimal digits. The reconstructed serial number is ((11.053 * 1000000000) + 11.052).

Example 1
Serial number "1234567898765" would be stored as 11.053 = 1234, 11.052 = 567898765.

Example 2
Serial number "1234000056789" would be stored as 11.053 = 1234, 11.052 = 56789. Serial Number LS (11.052) will be shown on the keypad as 000056789 (i.e. including the leading zeros).

See Serial Number LS (11.052).

Drive Date Code (11.054) is a four-digit number in the form yyww where yy is the year and ww the week number.

Onboard User Program: Clock Task Scheduled Interval (11.055) shows the interval at which the clock task is scheduled to run at in ms.

If Option Slot Identifiers (11.056) is set to its default value of 0 each option module is assigned the same slot number as its physical slot. For example the module in physical slot 1 appears in slot 1 to all drive and option module software systems (i.e. it uses Menu 15 as its set-up menu and Menu 25 as its application menu etc.). This arrangement can be changed by selecting a different value for Option Slot Identifiers (11.056). Although Option Slot Identifiers (11.056) is a volatile parameter its value is saved in non-volatile memory when parameters are saved. If Option Slot Identifiers (11.056) is changed the drive must be powered down and then powered up again for the change to take effect.

See  Maximum Heavy Duty Rating (11.032).

Maximum Rated Current (11.060) defines the variable maximum VM_RATED_CURRENT[MAX] which defines the maximum for Rated Current (05.007).

Full Scale Current Kc (11.061) shows the full scale current in r.m.s. Amps. If the drive current exceeds this level it will cause an over current trip.

Power Board Software Version Number (11.062) gives the version for the power board connected to the control board or the power board in node 1 of a multi-power module drive.

Product Type (11.063) shows the core product type as given in the table below. The drive could be the basic product or a derivative of the basic product as defined by Drive Derivative (11.028).

The drive model and rating can be identified as AAAA B nnnnnnnn CCCC DD EE FFF where each section of the model identifier is taken from a parameter. AAAA, B, CCCC, DDDD, EE and FFF are alpha-numeric characters. nnnnnnnn are decimal digits.

Drive Rating And Configuration (11.065) is split into a number of fields as defined in the table below.

Example
The model number M700-03400078 A001 00 AB100 would be displayed in parameters as follows

See Product Identifier Characters (11.064).

Power Stage Identifier (11.066) is used to show power stages that require changes to the drive user parameters (i.e. visibility, range or defaults). It should be noted that this parameter does not identify the rating of the power stage.

Control Board Identifier (11.067) identifies the control board hardware in the form A.0BC. A indicates whether this is a standard (0) or high speed (1) product, B indicates standard current feedback (0) or current feedback with Ia and Ic swapped (1), and C is the control board type.

Internal I/O Identifier (11.068) identifies the internally fitted I/O option as given in the table below.

The tables below show which I/O functions are available for each of the internally fitted I/O options.

¹ Only one hardware input is provided which is shared by STO1 and STO2.

Position Feedback Interface Identifier (11.069) identifies the type of interface fitted in the position feedback interface option location as given in the table below.

Core Parameter Database Version (11.070) gives the version number of the parameter database used to define the core parameter menus in the drive (Menu 1 to 14 and 21 to 23) in 2 digit BCD format. All other menus are customisable and if these menus are changed their default values are automatically loaded. However, if the drive software is changed it may be necessary to load defaults for all menus, although this will only be required rarely. Defaults for all menus are loaded when the most significant digit of Core Parameter Database Version (11.070) changes. Therefore if the drive firmware is modified and the most significant digit of the core database version has changed an EEPROM Fail.001 trip is initiated and default parameters are loaded.

Number Of Power Modules Detected (11.071) shows the number of power modules detected in a drive. See Number Of Power Modules Test (11.035) for details.

If NV Media Card Create Special File (11.072) = 1 when a parameter file is transferred to an NV media card the file is created as a macro file. NV Media Card Create Special File (11.072) is reset to 0 after the file is created.

NV Media Card File Type (11.038) shows the type of non-volatile media card inserted in the drive.

NV Media Card Read-only Flag (11.075) shows the state of the read-only flag for the currently fitted card.

NV Media Card Warning Suppression Flag (11.076) shows the state of the warning flag for the currently fitted card.

The value of NV Media Card File Required Version (11.077) is used as the version number for a parameter file when it is created on an NV media card. NV Media Card File Required Version (11.077) is reset to 0 when the file is created or the transfer fails.

The version number is not applicable for user program files.

This parameter shows the status of any action on an NV media card that is initiated by setting a value in parameter mm.000. When the action starts this parameter changes to Active (1) and if the action completes successfully it changes back to None (0). If however, the action fails this parameter changes to another value to show the cause. Non-critical failures, i.e. an error that is detected when writing to a card, do not cause drive trips as these may disable the drive and disturb the wider system, and so this parameter is a way to find the cause of a non-critical error. 

Drive Name Characters 1-4 (11.079) to Drive Name Characters 13-16 (11.082) can be used to store a 16 character string which can be used to identify the drive. The string is arranged as shown below.

This uses the standard ASCII character set.

See Drive Name Characters 1-4 (11.079).

See Drive Name Characters 1-4 (11.079).

See Drive Name Characters 1-4 (11.079).

Drive Mode (11.084) is used to hold the currently active drive mode.

Security Status (11.085) shows the security that will apply when security is enabled by setting a non-zero value for User Security Code (11.030).

If Menu Access Status (11.086) = 0 then only Menu 0 can be accessed with a keypad. If Menu Access Status (11.086) = 1 then all menus can be accessed with a keypad.

Keypad Port Serial Address (11.090) defines the node address for the keypad port serial comms interface. Normally the default value of 1 is used, but this can be changed if required. The keypad attached to the port will sense the address automatically.

Changing the parameters does not immediately change the serial communications settings. See Reset Serial Communications (11.020) for more details.

Indicates how many controlled rectifiers connected to the drive have been detected. See Number Of Rectifiers Expected (11.096).

Number Of Rectifiers Expected (11.096) defines how many controlled rectifiers are expected on each power module. Within a complete drive with a diode input stage there are no controlled rectifiers. Within a complete drive with a controlled rectifier input stage there is one controlled rectifier. For a drive where external rectifiers are used the system can register up to nine controlled rectifiers. If Number Of Rectifiers Expected (11.096) = 0 then the rectifier monitoring system is disabled and the drive does not check how many controlled rectifiers are present. This is the default setting and should be used for complete drives with internal rectifiers because the monitoring function is not necessary. If Number Of Rectifiers Expected (11.096) is set to a non-zero value a check is made to ensure that at least this number of external rectifiers are connected to each power module. If there are less external rectifiers than defined by Number Of Rectifiers Expected (11.096) then a Configuration trip is initiated with the sub-trip indicating how many rectifiers should be present. See Trip 0 (10.020).
