The various control methods and the hardware of the frequency inverter include func-
tions which continuously monitor the application. The operational and error diagnosis
is facilitated by the information stored in the error protocol.

shows the number of errors which have occurred since initial commissioning 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 op-
erating hours can be read off via the
