13 ANALOG INPUTS
Analog input signal processing
1301 MINIMUM AI1 Defines the minimum %-value that corresponds to minimum mA/(V) signal for
analog input AI1. When used as a reference, the value corresponds to the
reference minimum setting.
0...20 mA 0...100%
4...20 mA 20...100%
Example: If AI1 is selected as the source for external reference REF1, this
value corresponds to the value of parameter 1104 REF1 MIN.
Note: MINIMUM AI value must not exceed MAXIMUM AI value.
0%
0…100.0% Value in percent of the full signal range. Example: If the minimum value for
analog input is 4 mA, the percent value for 0…20 mA range is:
(4 mA / 20 mA) · 100% = 20%
1302 MAXIMUM AI1 Defines the maximum %-value that corresponds to maximum mA/(V) signal
for analog input AI1. When used as a reference, the value corresponds to the
reference maximum setting.
0...20 mA 0...100%
4...20 mA 20...100%
Example: If AI1 is selected as the source for external reference REF1, this
value corresponds to the value of parameter 1105 REF1 MAX.
100
0…100.0% Value in percent of the full signal range. Example: If the maximum value for
analog input is 10 mA, the percent value for 0…20 mA range is:
(10 mA / 20 mA) · 100% = 50%
1303 FILTER AI1 Defines the filter time constant for analog input AI1, i.e the time within 63% of
a step change is reached.
0.1
0.0…10.0 s Filter time constant
14 RELAY OUTPUTS
Status information indicated through relay output and relay operating delays
1401 RELAY OUTPUT 1 Selects a drive status indicated through relay output RO. The relay energises
when the status meets the setting.
3 =
FAULT(-1)
0 = NOT SEL Not used
1 = READY Ready to function: Run Enable signal on, no fault, supply voltage within
acceptable range and emergency stop signal off.
2 = RUN Running: Start signal on, Run Enable signal on, no active fault.
3 = FAULT(-1) Inverted fault. Relay is de-energised on a fault trip.
4 = FAULT Fault
5 = ALARM Alarm
6 = REVERSED Motor rotates in reverse direction.
