3.
The error message was cleared by the error clearing command (cf.
"S-0-0099, C0500 Reset class 1 diagnostics").
4.
The drive is in the operating mode again and power was switched on
("Ab").
5.
Drive enable was switched on again (0-1 edge).
In case non-fatal safety technology errors are occurring
repeatedly, contact our service department as operating the drive
then is no longer allowed.
9.3.4
Behavior in the Case of Fatal Errors (F8xxx)
Generally, there are 3 types of fatal errors (F8 errors):
●
Fatal errors during initialization (e.g. F81xx)
●
Fatal errors during operation (e.g. F80xx)
●
Fatal safety technology errors (F83xx)
Fatal Errors During Initialization
(Initialization Errors)
Fatal initialization errors cannot be cleared but require that the drive be
restarted.
The drive can be restarted either by removing the 24-V supply or
(as of MPx17V08) by starting the "Reboot command" (C6400).
Fatal Errors During Operation
When a fatal error occurs during operation, control (or U/f control) of the drive
is no longer ensured; therefore, drive enable is immediately removed in case
of these errors and the holding brake - if available - is switched on.
Depending on the setting in "P-0-0119, Best possible deceleration", bit 8,
D.C. braking can be additionally activated.
With the corresponding setting in "P-0-0118, Power supply,
configuration", the power supply is disconnected in the case of
fatal errors.
Fatal Safety Technology Errors
When a fatal safety technology error occurs, the safety technology
immediately locks the output stage via two channels (in the case of an error
in the output stage interlock, possibly via one channel only) (STO) and - if
available and configured - switches the holding brake on (SBC). D.C. braking
(P-0-0119, bit 8) is no longer possible.
With the corresponding setting in "P-0-0118, Power supply,
configuration", the power supply is disconnected in the case of
fatal safety technology errors.

Commissioning Steps
After a fatal error has occurred, the drive can only be put into operation again
after the following steps were carried out:
1.
The cause of the error must be recognized and removed; this possibly
means that an entire component (e.g., motor or drive controller) must be
replaced.
2.
The error message must be cleared by the error clearing command [cf.
"S-0-0099, C0500 Reset class 1 diagnostics"] (for this purpose, it might
possibly be necessary to switch to the parameter mode or to switch the
drive off completely).
