Excessive
temperature end-
amplifier %
End-amplifier excessive
temperature.
The error is not reset after status
inquiry (address=%1).
Turn the system off. Check the motor
temperature and heat sink temperature
(DMS/SMS) and allow them to cool down.

439
Error in current
monitoring end-
amplifier %
End-amplifier current
monitoring error (address=%1).

position exceeded
%
The defined maximum position
was exceeded (address=%1).
The position to be reached is farther than
the maximum positions indicated in the

determine which position should be
reached. Is this position correct? If yes,
adapt to the maximum position of the
corresponding motor/ parameter.
