9.3.3.22 Parameter set error PR1, PR2, PR3, PR4
Purpose
Controller protection
Function
During load, each of the parameter sets is checked if it is complete and correct. If a difference should
be recognized, the controller changes to the TRIP state. The incorrect parameter set is displayed
(C0168; PR1 = parameter set1 etc.).
At the same time, the default setting is loaded, but not saved (after TRIP-RESET the controller
operates with the default settings, until the setting is changed).
The cause can be a transmission error during the transmission of parameter sets to the controller.
Remedy:
The corresponding parameter set must be reset or transmitted to the controller again.
This interference can also be caused by an interrupt of the transmission of parameter sets by the
operating unit (e.g. by an early disconnection of the operating unit).
