4.3 Error messages
Errors which occur are shown in coded form by an error number in the LED display on the front
panel. All error messages result in the BTB/RTO contact being opened, and the output stage of the
amplifier being switched off (motor loses all torque). If a motor-holding brake is installed, it will be
activated.
