# Menu 7 − Analog I/O

Mode: RFC‑A

Analog Outputs
The update rate for analog outputs is 250μs; although the output will only change at the update rate defined by the source parameter for the input. The following exceptions apply:

1. Speed Feedback (03.002) has an update rate of 4ms and includes a 16ms window filter. If this parameter is selected as a source for output 2 the update rate of the source changes to 250us and the only filter applied is the window filter associated with the position feedback interface (i.e. P1 Feedback Filter (03.042) for the P1 interface). It should be noted that this feature is only provided when the position feedback is from a drive interface and not from an option module.
2. If either analogue output is set up for current mode then the update rate for both analogue outputs is 4ms.

Analog Inputs
The normal sample rate for the analog inputs is 4ms, however this is increased to 250us for analogue inputs 1 and 2 under the following conditions:

1. The maximum and the minimum for the input are at their default values of 100.00% and -100.00% respectively.
2. The input is set to voltage mode.
3. One of the destinations given in the table below must be selected.
4. If the destination is Analog Reference 1 (01.036) or Analog Reference 2 (01.037) the reference system must not be in uinpolar mode, i.e. Bipolar Reference Enable (01.010) must be one.

Note that Analogue Input 1 Fast Update Active (07.026) and Analogue Input 2 Fast Update Active (07.027) indicate if fast updating is active for each input.

Each analogue input has a resolution of 11 bits plus sign. The inputs can operate in different modes (defined by Analog Input 1 Mode (07.007) for analogue input 1). These modes include voltage, current and thermistor modes. The available modes depend on the hardware configuration and are given in the table below.

Internal I/O Identifier (11.068) | Analogue Input 1 | Analogue Input 2 | Analogue Input 3
0: Standard Analogue and Digital I/O | Bipolar Voltage, Current | Bipolar Voltage, Current | Bipolar Voltage, Thermistor
1: Digital I/O | Not present | Not present | Thermistor, Disabled
2: HVAC Analogue and Digital I/O | Unipolar Voltage, Current, Thermistor | Unipolar Voltage, Current, Thermistor | Not present

The "Input Level" is defined for the different modes in the table below.

Mode | Input Level
Voltage | (Input Voltage / 10V) x 100.00%
0-20mA | (Input Current / 20mA) x 100.00%
20-0mA | ((20mA - Input Current) / 20mA) x 100.00%
4-20mA | ((Input Current - 4mA) / 16mA) x 100.00%
20-4mA | ((20mA - Input Current) / 16mA) x 100.00%
Thermistor | (Input resistance / 10K Ohm) x 100%

Analog Input 1 (07.001) is derived as follows:

Limits
A1 is the value after the minimum and maximum limits are applied.

If Analog Input 1 Minimum (07.040) ≥ Analog Input 1 Maximum (07.043) then:
A1 = 0.00% whatever the input level.

If Analog Input 1 Minimum (07.040) < 0.00% and Analog Input 1 Maximum (07.043) > 0.00% then:
A1 = Input Level x (100.00% / Analog Input 1 Maximum (07.043))
A1 is then limited between -100% and +100%.

Otherwise:
Input Level is limited between Analog Input 1 Minimum (07.040) and Analog Input 1 Maximum (07.043)
A1 = [Input Level - Analog Input 1 Minimum (07.040)] x 100.00% / (Analog Input 1 Maximum (07.043) - Analog Input 1 Minimum (07.040))

For thermistor modes it should be noted that Analog Input 1 Minimum (07.040) and Analog Input 1 Minimum (07.040) have no effect and that the input resistance is limited between 0 and 5kΩ.

Thermal monitoring is provided within the drive to protect the power stage and the control system from over temperature.

Monitored Temperature 1 (07.004), Monitored Temperature 2 (07.005) and Monitored Temperature 3 (07.006) give an indication of the temperature of three selected monitoring points within the drive power system or control system. The required monitoring points can be selected using Temperature Monitor Select 1 (07.038), Temperature Monitor Select 2 (07.039) and Temperature Monitor Select 3 (07.052) respectively. The default values give two monitoring points in the power system in Monitored Temperature 1 (07.004) and Monitored Temperature 2 (07.005), and control board temperature 1 in Monitored Temperature 3 (07.006).

Analog Input 1 (07.001) is modified by Analog Input 1 Scaling (07.008), Analog Input 1 Offset (07.030) and Analog Input 1 Invert (07.009) before it is routed to its destination as follows:

A1O = Analog Input 1 (07.001) + Analog Input 1 Offset (07.030)

A1O is the value after the offset has been applied and is limited between -100.00% and 100.00%

A1S = A1O x Analog Input 1 Scaling (07.008)

A1S is the value after the scaling and the offset have been applied and is limited between -100.00% and 100.00%

If Analog Input 1 Invert (07.009) = 0 then A1I = A1S otherwise A1I = -A1S

A1I is the value after the invert, scaling and offset have been applied and is the final value that is routed to the destination defined by Analog Input 1 Destination (07.010).

Analog Output 1 Source (07.019) defines the source parameter for analog output 1. The value of the source parameter is scaled with Analog Output 1 Scaling (07.020) and if the scaling is greater than 1.000 the value is clamped between -100% and +100% or between 0% and 100% depending on whether the output is bipolar or unipolar. The resulting value is then used to control the output. It should be noted that the normal rules for parameter routing do not apply, but the scaling always makes -100% to +100% correspond to the range from minus source parameter maximum to plus source parameter maximum, and 0% corresponds to the source parameter value of zero. This means for example that a parameter with a minimum of 1 and a maximum of 10 will produce an output that changes from 10% to 100% as the parameter is change from minimum to maximum.

The outputs provided with different hardware are given in the table below.

Internal I/O Identifier (11.068) | Analogue Output 1 | Analogue Output 2

Analog Output 2 Source (07.022) defines the source parameter for analog output 1. The value of the source parameter is scaled with Analog Output 2 Scaling (07.023) and if the scaling is greater than 1.000 the value is clamped between -100% and +100% or between 0% and 100% depending on whether the output is biploar or uniploar.

For analog input 1, and in voltage mode only, the full scale value used to determine the input level can be changed from 10V by calibrating the input. The calibration process is triggered by setting Calibrate Analog Input 1 Full Scale (07.025) to one. Calibrate Analog Input 1 Full Scale (07.025) is cleared automatically when the calibration process is complete. After calibration the actions are as follows:

Input voltage during calibration | Result
V < 1.5V | The calibration result is ignored and the full scale is set to 10V. Analog Input 1 Full Scale (07.051) is set to zero.
1.5V < V < 2.5V | The calibration result is ignored and the full scale or Analog Input 1 Full Scale (07.051) are not affected.
V > 2.5V | The calibration result is used to set full scale and the value is also stored in Analog Input 1 Full Scale (07.051).

It should be noted that Analog Input 1 Full Scale (07.051) is a power-down save parameter, and so the result is automatically retained after power-down.

This is an instantaneous power output with fast update rate that is primarily intended to be used as a power feed-forward for applications with a Regen system front end. The full scale (100.0%) value is equal to a power of 3 x (VM_DC_VOLTAGE[MAX] / 2√2) x Full Scale Current Kc (11.061). This is compatible with the power output provided in Unidrive SP and is directly comptible with Power Input 1 (03.010) (and the other power feed-forward parameters) in Regen mode. The scaling is intended to cover the maximum range of likely power in the drive. For example with a 400V 7.5kW drive the full scale d.c. link voltage is 831V and Kc=38.222A, and so the full scale value of this parameter is 3 x (831 / 2√2) x 38.222 = 33.689kW. For Open-loop, RFC-A and RFC-S modes a positive value of power indicates power flowing from the drive to motor. For Regen mode a positive value of power indicates power flowing from the supply to the regen drive.

Percentage Of Drive Thermal Trip Level (07.036) gives the percentage of the thermal trip level of the temperature monitoring point or thermal model in the drive that is highest. This includes all thermal monitoring points (not just those selected by Monitored Temperature 1 (07.004), Monitored Temperature 2 (07.005) and Monitored Temperature 3 (07.006)), Inverter Temperature (07.034) and Percentage Of d.c. Link Thermal Trip Level (07.035).

Percentage Of d.c. Link Thermal Trip Level (07.035) is used directly to give Percentage Of Drive Thermal Trip Level (07.036), but for all other monitored values which are temperatures this is given by Percentage of thermal trip level = (Temperature - 40oC) / (Trip temperature - 40oC) x 100%

The location of the measurement or the thermal model that is related to this temperature is given in Temperature Nearest To Trip Level (07.037). If Percentage Of Drive Thermal Trip Level (07.036) exceeds 90% Drive Over-temperature Alarm (10.018) is set to one. If Percentage Of Drive Thermal Trip Level (07.036) reaches 100% one of the trips given in the table below is initiated. The trip can be reset when the percentage of thermal trip level fall below 95%.

Analog Input 3 Thermistor Type (07.046) defines the operation of the temperature feedback interface for analog input 3 when Analog Input 3 Mode (07.015) is set up for a temperature feedback mode. When a temperature feedback mode is selected a 2mA current source is connected to analog input 3 to supply the temperature feedback device that is connected to the input.

Analog Input 3 Thermistor Type (07.046) | Compatible devices
0: DIN44082 | Three thermistors in series as specified in DIN44082 standard
1: KTY84 | KTY84 PTC thermistor
2: PT100 (4W) | PT100 PTC thermistor with 4 wire connection
3: PT1000 (4W) | PT1000 PTC thermistor with 4 wire connection
4:PT2000 (4W) | PT2000 PTC thermistor with 4 wire connection
5: 2.0mA (4W) | Any device. Full scale equivalent to a resistance of 5k Ohms with 4 wire connection
6: PT100 (2W) | PT100 PTC thermistor with 2 wire connection
7: PT1000 (2W) | PT1000 PTC thermistor with 2 wire connection
8: PT2000 (2W) | PT2000 PTC thermistor with 2 wire connection
9: 2.0mA (2W) | Any device. Full scale equivalent to a resistance of 5k Ohms with 2 wire connection

DIN44082 and KTY84 devices should always be connected directly to analog input 3. The other devices can be connected directly to analog input 3 if the 2 wire connection option is selected. Alternatively these devices can be used with a 4 wire connection to remove the effect of voltage drops due to the 2mA supply current via the path shown below. If a 4 wire connection is selected analog input 1 is disabled and Analog Input 1 (07.001) always reads as 0.0%. It should be noted that the input system takes account of the input impedance of analogue input 3 when 2 wire mode is used, and of both analogue input 1 and analogue input 3 when 4 wire mode is used. For this reason it is important that 2 wire mode is selected when the connection between Analogue Input 1+ and Analogue input 3 is not present, and that 4 wire mode is selected if the connection is present.
