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:
Enter the low voltage value. This analog input scaling value should correspond to the minimum
reference value, set in par. 3-02 Minimum Reference
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 low current value. This reference signal should correspond to the minimum reference
value, set in par. 3-02 Minimum Reference
Live Zero Time-out Function in par. 6-01
Function:
Enter the high current value corresponding to the high reference/feedback value set in
Terminal 54 High Ref./Feedb. Value
par. 6-25
Function:
Enter the analog input scaling value that corresponds to the minimum reference feedback value set
Minimum Reference
in par. 3-02 .
Function:
Enter the analog input scaling value that corresponds to the maximum reference feedback value set
in par. 3-03 Maximum Reference .
Function:
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 dampening but also increases
the time delay through the filter.
This parameter cannot be adjusted while the motor is running.
