190 Parameters
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
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.
See also parameter 12.19 AI1 scaled at AI1 min.
0.000
0.000…11.000 V Minimum value of AI1. 1000 = 1
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.
See also parameter 12.19 AI1 scaled at AI1 min.
10.000
0.000…11.000 V Maximum value of AI1. 1000 = 1
