SINUMERIK, SIMODRIVE Diagnostics Manual (DA), 11/2006 Edition
300613 Axis %1 drive %2 maximum permissible motor temperature exceeded
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 1. The motor temperature (measured by the temperature sensor KTY 84 and fed to the module
through the motor encoder cable) has exceeded the temperature limit in MD 1607:
$MD_MOTOR_TEMP_SHUTDOWN_LIMIT (motor temperature shutdown limit).
2. The thermal motor monitoring has triggered because the thermal load on the motor model MD 1266
had reached the 100% value.
The alarm can be reconfigured in MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: Mode group 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.
Remedy: Please inform the authorized personnel/service department.
- Motor overloaded.
- Check the motor data. Possibly the machine current was too high as a result of incorrect motor data.
- Check the temperature sensor (2nd sensor possible with MSD).
- Check the motor encoder cable.
- Motor encoder defective.
- Check the motor fan.
- Check the acceleration.
- If necessary, use a higher-performance motor.
- Winding fault in motor.
- 611D control module defective.
- Modify MD 1230: $MD_TORQUE_LIMIT (1st torque limit), MD 1235: POWER_LIMIT (1st power
limit) set too high.
Program
Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
