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.
Number
E / S / A / P Status Messages
* = These error messages can be cancelled by the ASCII command CLRFAULT, without executing a reset. If
only these errors are present, and the RESET button or the I/O-function RESET is used, the CLRFAULT com-
mand is also all that is carried out.
More information about faults and hints for removal can be found on page 92

Explanation
Status messages, no error, see p. 60
updating the startup configuration
heat sink temperature too high
limit is set by manufacturer to 80°C (176°F)
overvoltage in DC bus link
limit depends on the mains supply voltage
message from the position controller
cable break, short circuit, short to ground
undervoltage in DC bus link
limit is set by manufacturer to 100V
motor temperature too high
limit is set by manufacturer to145°C (293°F)
internal aux. voltage not OK
motor running away, speed is too high
checksum error
checksum error
cable break, short circuit, short to ground
motor phase missing (cable break or similar)
internal temperature too high
fault in the output stage
I²t max. value exceeded
2 or 3 phases missing in the supply feed
error in the analog-digital conversion, usually caused by ex-
cessive EMI
