Operating Instructions
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the filter time constant. This
constant is a first-order digital low-pass
filter time for suppressing electrical noise
in terminal 53. A high value improves
dampening, but also increases the delay
through the filter.
Function:
Disables the live zero monitoring, for example if
the analog outputs are used as part of a
decentral I/O system (i.e. if these are used to feed
a Building Management System with data, and
not as part of any control functions related to the
frequency converter).
Function:
Enter the low-voltage value. This analog
input scaling value should correspond to
the low reference/feedback value, set in
parameter 6-24 Terminal 54 Low Ref./Feedb.
Value.
Function:
Enter the high-voltage value. This analog
input scaling value should correspond to the
high reference/feedback value set in
parameter 6-25 Terminal 54 High Ref./Feedb.
Value.
Function:
Enter the analog input scaling value that
corresponds to the low voltage/low
current value set in
parameter 6-20 Terminal 54 Low Voltage
and 6-22 Terminal 54 Low Current.

Enter the filter time constant. This is a
first-order digital low-pass filter time
