6-24 Terminal 54 Low Ref./Feedb. Value
Range:
Function:
0.000 N/A* [-999999.999 - 999999.999 N/A]
Enter the analog input scaling value that corresponds to the low voltage/low current value set in
par.6-20
and par. 6-22
Terminal 54 Low Current
.
6-25 Terminal 54 High Ref./Feedb. Value
Range:
Function:
100.000 N/
A*
[-999999.999 - 999999.999 N/A]
Enter the analog input scaling value that corresponds to the high voltage/high current value set in
par.6-21
and par. 6-23
Terminal 54 High Current
.
6-26 Terminal 54 Filter Time Constant
Range:
Function:
0.001 s*
[0.001 - 10.000 s]
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 damping, but also increases the
time delay through the filter.
This parameter cannot be adjusted while the motor is running.
6-27 Terminal 54 Live Zero
Option:
Function:
This parameter makes it possible to disable the Live Zero monitoring. For example, this to be used
if the analog outputs are used as part of a de-central I/O system (e.g., when used not as part of
any adjustable frequency drive related control functions, but for feeding a building management
system with data).
