AL.003 Motor Overload CiA402 Error Code 0x3230-02-0003
Alarm Cause
If continuing to use the Driver more than the Rated Load, this Error Alarm will be
generated, please refer to the Overload Protection Curve.
Overload Protection Curve under 1kW
Overload Protection Curve over 1kW
1. Incorrect wiring of motor and encoder.
2. Poor parameter setting of control system.
3. Acceleration/deceleration setting time too short or load inertia too large.
4. Cn030 Setting error.
5. Not able to drive the motor because of mechanical factors and results in
excessive load during operation.
6. Driver hardware failure.
Check and
Handling
1. Check if the Motor Terminal wiring (U, V, W) and Encoder wiring is correct;
please wire in accordance with Chapter 2 Servo Driver Power and Peripheral
Wiring Diagram.
2. Adjust the Driver Gain since improper Gain Adjustment will cause Motor
resonance and result in excessive current to cause Motor Overload.
3. In operation program, Un-04 monitors the average torque (%) keeps above
100% continuously and extends acceleration/deceleration time or reduce load
inertia within permitted range.
