Emergency telegram
The controller monitors the functioning of its main components, e. g. voltage supply and
power stage. In addition, the motor (temperature, phase-angle encoder) and the limit
switches are checked continuously. Incorrect parameter settings can also lead to error
messages (division by zero, etc.).

The drive controller sends an emergency telegram if an error occurs. The identifier of this
message is composed of the identifier
80
h
and the
node address
of the drive controller
concerned.
The emergency telegram consists of eight bytes. The first and second byte contain the
error_code
. In the third byte there is an additional error code (object 1001
h
). The fourth to
eighth byte are always set to zero.
The following error codes may appear:
