Parameters 117
12.16 AI1 filter time
Defines the filter time constant for analog input AI1.
Note: The signal is also filtered due to the signal
interface hardware (approximately 0.25 ms time
constant). This cannot be changed by any parameter.
0.100 s
0.000…30.000 s Filter time constant. 1000 = 1 s
12.17 AI1 min
Defines the minimum site value for analog input AI1.
Set the value actually sent to the drive when the
analog signal from plant is wound to its minimum
setting.
4.000 mA or
0.000 V
0.000…22.000 mA or
0.000…11.00 V
Minimum value of AI1. 1000 = 1 mA
or V
12.18 AI1 max Defines the maximum site value for analog input AI1.
Set the value actually sent to the drive when the
analog signal from plant is wound to its maximum
setting.
20.000 mA
or 10.00 V
0.000…22.000 mA or
0.000…11.00 V
