Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/
Terminal 53 Low Ref./Feedb. Value .
feedback value set in par. 6-14
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 analog input scaling value that corresponds to the low voltage/low current set in
par. 6-10 Terminal 53 Low Voltage and par. 6-12 Terminal 53 Low Current .
Function:
Enter the analog input scaling value that corresponds to the high voltage/high current value set in
Terminal 53 High Voltage and par. 6-13 Terminal 53 High Current .
par. 6-11
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 de-central I/O system (e.g. when not as part of any frequency con-
verter 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 Terminal 54 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. 6-25
Function:
Enter the analog input scaling value that corresponds to the low voltage/low current value set in
Terminal 54 Low Voltage and par. 6-22 Terminal 54 Low Current .
