Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par. 6-14
Terminal 53 Low Ref./Feedb. Value
Function:
Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 6-15
Function:
Enter the low current value. This reference signal should correspond to the low reference/feedback

to activate the Live Zero Timeout Function in par. 6-01
Function:
Enter the high current value corresponding to the high reference/feedback set in par. 6-15

.
Function:
Enter the analog input scaling value that corresponds to the low voltage/low current set in
Terminal 53 Low Voltage
par. 6-10
and par. 6-12
Function:
Function:
Enter the time constant. This is a first-order digital low pass filter time constant for suppressing
electrical noise in terminal 53. A high time constant value improves dampening but also increases
the time delay through the filter.
This parameter cannot be adjusted while the motor is running.
Function:
This parameter makes it possible to disable the Live Zero monitoring. For example, this is to be used
if the analog outputs are used as part of a de-central I/O system (e.g., when not used as part of
any adjustable frequency drive related control functions, but for feeding a building management
system with data).
