Term. X42/3 Low Ref./Feedb. Value
feedback value set in par. 26-24
Function:
Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 26-25
Function:
Enter the analog input scaling value that corresponds to the low voltage value set in
par. 26-20 Terminal X42/3 Low Voltage
Function:
Enter the analog input scaling value that corresponds to the high voltage value set in
par. 26-21 Terminal X42/3 High Voltage
Function:
Enter the time constant. This is a first-order digital low pass filter time constant for suppressing
noise in terminal X42/3. 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 enable the Live Zero monitoring. E.g. where the analog input
is a part of the frequency converter control, rather than being used as part of a decentral I/O system,
such as a Building Management System.
Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par. 26-34 Term. X42/5 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. 26-35
