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 an external control system with data)
Function:
Sets the analog input scaling value to correspond to the low reference/feedback value set in
Term. X30/12 Low Ref./Feedb. Value
