Function:
Enter the analog input scaling value that corresponds to the high voltage/high current value set in par. 6-21 and
par. 6-23.
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.
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:
Sets the analog input scaling value to correspond to the low reference/feedback value (set in par. 6-34).
Function:
Sets the analog input scaling value to correspond to the high reference/feedback value (set in par. 6-35).
Function:
Sets the analog input scaling value to correspond to the low voltage value (set in par. 6-30).
Function:
Sets the analog input scaling value to correspond to the high voltage value (set in par. 6-31).
Function:
A 1 st order digital low pass filter time constant for suppressing electrical noise on terminal X30/11.
Par. 6-36 cannot be changed 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)
