Error and warning messages
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.
Description see parameter ERRCODE.

* = 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 command is also all that is carried out.
Warning messages
Faults that occur, but do not cause a switch-off of the output stage of the amplifier (BTB/RTO contact remains closed), are displayed as a coded warning number in the LED-display on the front panel, and shown in the screen page "STATUS". Warnings that are recognized by the supply monitoring are only reported after the servo amplifier has been enabled.
