Fatal errors during initialization (in‐
itialization errors F81xx)
Fatal initialization errors (F81xx) cannot be cleared but require that the drive
be restarted.
Fatal axis errors during operation
(F80xx)
Axis reaction: If a fatal error occurs during operation (F80xx), closed-loop
control (or open-loop V/Hz [U/f] control) of the drive is no longer ensured.
Therefore, drive enable is immediately removed in the 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, a motor phase short circuit
can be additionally activated.
Supply unit reaction: none
With the corresponding power supply configuration (P‑0‑0118),
the power supply is disconnected in the case of all fatal errors.
Fatal axis and supply unit errors
during operation (F88xx)
Axis reaction: Like for "fatal axis errors during operation (F80xx)"
Supply unit reaction: The mains supply is switched off immediately; switching
off with a delay is not possible.
Fatal safety technology errors
(F83xx)
If a fatal safety technology error occurs (F83xx), 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 on the holding brake (SBC). D.C. braking
(P‑0‑0119, bit 8) is no longer possible.
With the corresponding power supply configuration (P‑0‑0118),
the power supply is disconnected in the case of fatal safety
technology errors.
Commissioning steps
After a fatal error has occurred, the drive controller can only be put into
operation again after the following steps were carried out:
1.
The cause of the error has to be recognized and removed. This possibly
means that an entire component (e.g., motor or drive controller) has to
be replaced.
2.
The error message has to be cleared by the error clearing command
[C0500 (S‑0‑0099)] (for this purpose, it might be necessary to switch to
the parameter mode or to switch off the drive controller completely).
3.
The supply unit has to be switched back on.
4.
The drive controller has to be in the operating mode again, and power
has to be switched back on ("Ab").
5.
Drive enable has to be switched back on (positive edge).
In case fatal errors occur repeatedly, contact our service
department since operating the drive controller then is no longer
possible.

Removing malfunctions, maintenance measures, deactivat‐
ing the motors
When removing malfunctions, performing maintenance measures
or deactivating the motors, observe the safety instructions in the
chapter "Safety instructions for electric drives and controls"!
In the case of malfunctions, maintenance measures or to deactivate the
motors, proceed as follows:
●
Observe the instructions contained in the machine documentation.
