Motor Overheat (OHAL)

What does 306 mean?

The motor has overheated (OHAL), causing its internal thermostat to trip. This indicates that the motor's operating temperature has exceeded safe limits, potentially due to severe conditions or high ambient heat.

• Motor overheating due to excessively strict operating conditions (e.g., heavy load, high speed, high duty cycle).
• Excessively high ambient temperature surrounding the motor, preventing adequate cooling.
• Motor's internal thermostat has tripped due to overtemperature.

1. 1

   Investigate and reduce the severity of motor operating conditions.

2. 2

   Verify that the ambient temperature around the motor is within specified limits.

3. 3

   If the alarm recurs after the motor has cooled down, replace the faulty motor or servo amplifier.
