11 Operational and error diagnosis
The various control methods and the hardware of the device include functions which continuously monitor
the application. The operational and error diagnosis is facilitated by the information stored in the error
protocol.
11.1 List of errors
The last 16 fault messages are stored in chronological order and
No. of Errors
362 shows the number of
errors which have occurred since initial commissioning of the frequency inverter. The error code FXXXX is
displayed in menu branch VAL of the control unit. For the meaning of the error code, refer to the following
chapter “Error messages”. Via the PC user interface, the number of operation hours (h), operation minutes
(m) and the fault message can additionally be read out. The current operating hours are shown by
parameter
Operating hours counter
245. The fault report can be acknowledged via the keys of the
operating unit and according to the assignment
Error acknowledgment
103.
List of errors
No. Description Function
310 Last Error hhhhh:mm ; FXXXX error message.
311 Last Error but one hhhhh:mm ; FXXXX error message.
312 to 325 Error 3 to error 16.
362 No. of Errors
Number of errors occurred after the initial commissioning of the
frequency inverter.
The error and warning behavior of the frequency inverter can be set in various ways. The automatic error
acknowledgment enables acknowledgment of the faults Overcurrent F0500, Overcurrent F0507 and
Overvoltage F0700 without intervention by an overriding control system or the user. The
No. of self
acknowledged Errors
363 shows the total number of automatic error acknowledgments.
