20 Error Protocol
The various control methods and the hardware of the frequency inverter include
functions which continuously monitor the application. The operational and error diag-
nosis is facilitated by the information stored in the error protocol.
20.1 Error List
The last 16 fault messages are stored in chronological order and the No. of errors
362 shows the number of errors which have occurred since initial commissio
ning of
the frequency inverter. In the VAL menu branch of the control unit, the error code
FXXXX is displayed. The meaning of the error key is described in the following chap-
ter "Error Messages". Via the PC program, the number of operation hours (h), opera-
tion minutes (m) and the fault message can additionally be read out. The current
operating hours can be read off via the Operation hours counter 245. The fault re-
port can be acknowledged via the keys of the operating unit and according to the
assignment Error acknowledgment 103.
No.
Description Function
310
Last error hhhhh:mm ; FXXXX fault message.
311
Last error but one hhhhh:mm ; FXXXX fault message.
Error 3 to error 16.
362
No. of errors
Number of errors occurred after the initial com-
missioning 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 Overcur-
rent 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.
No. of self acknowledged
errors
Total number of automatic error acknowledg-
ment with synchronization.
20.1.1 Error Messages
The error code stored following a fault comprises the error group FXX and the fol-
lowing code number XX.
F00 00 No fault has occurred.
Overload
Frequency inverter overloaded.
F01
Frequency inverter overloaded (60 s), check load behavior.
Short-term overload (1 s), check motor and application parameters.
