Sinumerik Alarm 300613 Axis %1 drive %2 maximum permissible motor temperature exceeded
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The motor temperature (measured via the temperature sensor KTY 84 and fed to the module through the motor encoder cable) has exceeded the temperature limit in drive MD 1607: $MD_MOTOR_TEMP_SHUTDOWN_LIMIT (motor temperature shutdown limit). The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
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.
