current value set in
parameter 6-20 Terminal 54 Low Voltage
and parameter 6-22 Terminal 54 Low
Current.
6-25 Terminal 54 High Ref./Feedb. Value
Range: Function:
100 [-999999.999 - Enter the analog input scaling value

high current value set in
parameter 6-21 Terminal 54 High
Voltage and parameter 6-23 Terminal 54
High Current.

Enter the time constant. This is a first-
order digital low pass filter time constant
for suppressing electrical noise in terminal
54. A high time constant value improves
dampening but also increases the time
delay through the filter.
6-27 Terminal 54 Live Zero
Option: Function:
[0] Disabled
[1] Enabled This parameter makes it possible to disable the
Live Zero monitoring. E.g. to be used if the analog
outputs are used as part of a decentral I/O system
(e.g. when not part of any frequency converter
related control functions, but feeding an external
control system with data)
