36.1
Error messages
Errors that occur are displayed as a coded error number in the LED-display on the front panel, and in the
"STATUS" screen page. All error messages result in the BTB/RTO contact being opened and the output stage
of the amplifier being switched off (the motor loses all torque). The motor-holding brake is activated. Errors that
are recognized by the mains supply monitoring are only reported after the servo amplifier has been enabled.
* = These error messages can be canceled by the ASCII command CLRFAULT, without making a reset. If only
these errors are present, and the RESET button or the I/O-function RESET is used, the CLRFAULT command
is also all that is carried out.

Explanation
heat sink temperature is too high,
the limit is set by the manufacturer to 80°C
overvoltage in the DC-link circuit,
the limit depends on the mains supply voltage
message from the position controller
cable break, short-circuit, short to ground
undervoltage in DC-link,
the limit is set by the manufacturer to 100V
temperature sensor faulty or motor temperature too high,
the limit is set by the manufacturer to 145°C
internal aux. voltage not OK
motor running away, the speed is higher than permitted
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 power output stage
I²t max. value exceeded
2 or 3 supply phases missing
error in the analog-digital conversion
regen circuit faulty or incorrect setting
a supply phase is missing
(can be switched off for 2-phase operation)
Hardware error on the expansion card
Software error on the expansion card
40/70 amps types only: Short circuit to earth
CAN bus total communication error
Warning display as error
Commutation error
Homing error (Hardware limit switch reached)
Operating error for AS-option
reserved
Sercos error
Emerg. Stop Timeout
wrong Firmware Version
