Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/feedback
value set in par 26-34.
Function:
Enter the high voltage value. This analog input scaling value should correspond to the high reference/feedback
value set in par 26-35.
Function:
Enter the analog input scaling value that corresponds to the low voltage value set in par 26-30.
Function:
Enter the analog input scaling value that corresponds to the high voltage value set in par 26-21.
Function:
Enter the time constant. This is a first-order digital low pass filter time constant for suppressing noise in terminal
X42/5. 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:
Set the function of terminal X42/7 as an analog voltage output.
