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.

0.000…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.
