Alarm 300614

Siemens 300614 - Axis drive time monitoring of motor temperature

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 1602: $MD_MOTOR_TEMP_WARN_LIMIT for a longer period of time than permitted in drive machine data 1603 $MD_MOTOR_TEMP_ALARM_TIME. $MD_MOTOR_TEMP_ALARM_TIME (time stage motor temperature alarm). The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready) Control 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.

Axis drive time monitoring of motor temperature

Safety

  • Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.
  • Hot surfaces and stored energy: allow the motor to cool and isolate power before working on the motor or encoder (lockout/tagout).

Common Causes

  • 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 1602: $MD_MOTOR_TEMP_WARN_LIMIT for a longer period of time than permitted in drive machine data 1603 $MD_MOTOR_TEMP_ALARM_TIME. $MD_MOTOR_TEMP_ALARM_TIME (time stage motor temperature alarm).
  • The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready)

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Motor overloaded.
  3. 3Check the motor data.
  4. 4Possibly the machine current was too high as a result of incorrect motor data.
  5. 5Check the temperature sensor.
  6. 6Check the motor encoder cable.
  7. 7Clear alarm with the RESET key in all channels of this mode group. Restart part program
