Cause : Motor Overheat (PTC Input) comes when the thermistor wiring that detects motor temperature is defective. Correct wiring errors.
- The motor overheat signal to analog input terminal A1 or A2 exceeded the alarm detection level.
- Detection requires multi-function analog input H3-02 or H3-10 be set to “E”.
- Check the size of the load, the accel/decel times, and the cycle times.
- Decrease the load.
- Increase the acceleration and deceleration times (C1-01 through C1-08).
