Cause : Motor Overheat Fault (PTC Input) comes when the motor has overheated or the temperature of the motor has exceeded the safe operating limit.
- Check the load level, acceleration/deceleration time, and motor start/stop frequency (cycle time).
- Decrease the load.
- Increase the values set in C1-01 to C1-08 [Acceleration/ Deceleration Times].
- Set E2-01 [Motor Rated Current (FLA)] correctly to the value specified by the motor nameplate.
- Make sure that the motor cooling system is operating correctly, and repair or replace it if it is damaged.
- Adjust E1-04 to E1-10 [V/f Pattern Parameter
- Adjust E1-04 to E1-10 [V/f Pattern Parameters]. For motor 2, adjust E3-04 to E3-10.
- Decrease the values set in E1-08 [Mid Point A Voltage] and E1-10 [Minimum Output Voltage].
