Remedy:
Program Continuation:
Axis %1 drive %2 zero load current > rated motor current
%1 = NC axis number %2 = Drive number
The no-load current of the motor (MD 1136: $MD_MOTOR_NOLOAD_CURRENT) has been set at a greater value than the rated current of the motor (MD 1103: $MD_MOTOR_NOMINAL_CURRENT).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Please inform authorized personnel / the service department.
For standard motors: Execute a general drive reset (delete the boot file) and repeat the startup.
For non-Siemens motors: Check and, if necessary, refer to the motor data sheet to correct machine data MD 1103: $MD_MOTOR_NOMINAL_CURRENT (nominal motor current) and MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current). Clear alarm with the RESET key in all channels. Restart part program.
