• 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.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 drive %2 time monitoring of motor temperature
%1 = NC axis number
%2 = Drive number
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

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).

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.
• Check the motor encoder cable.
• Check the motor fan.

• 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.
