current value set in
parameter 6-20 Terminal 54 Low Voltage

6-25 Terminal 54 High Ref./Feedb. Value
Range: Function:

voltage/high current value set in
parameter 6-21 Terminal 54 High

54 High Current.
6-26 Terminal 54 Filter Time Constant
Range: Function:

This parameter cannot be adjusted
while the motor is running.
Enter the filter time constant. This is a
first-order digital low-pass filter time
constant for suppressing electrical noise in
terminal 54. Increasing the value improves
dampening but also increases the time
delay through the filter.
6-27 Terminal 54 Live Zero
Option: Function:
Disables the live zero-monitoring, for example if
the analog outputs are used as part of a
decentral I/O system (that is if these are used to
feed a building management system with data,
