Function:
Enter the analog input scaling value that corresponds to the low voltage/low current set in par. 6-10 and par.
6-12.
Function:
Enter the analog input scaling value that corresponds to the high voltage/high current value set in par. 6-11 and
par. 6-13.
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. 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 a Building Management system with data)
Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/feedback
value, set in par. 6-24.
Function:
Enter the high voltage value. This analog input scaling value should correspond to the high reference/feedback
value set in par. 6-25.
Function:
Enter the low current value. This reference signal should correspond to the low reference/feedback value, set in
par. 6-24. The value must be set at >2 mA in order to activate the Live Zero Time-out Function in par. 6-01.
Function:
Enter the high current value corresponding to the high reference/feedback value set in par. 6-25.
Function:
Enter the analog input scaling value that corresponds to the low voltage/low current value set in par. 6-20 and
par. 6-22.
