when we push the start button the motor cannot overcome the load on the belt. it started with a across the line starter. but of course, no control just run/stop

If the Control Techniques Commander SK2202 motor cannot overcome the load on the belt when the start button is pressed, possible issues include:

1. Low AC supply voltage – Insufficient voltage may prevent the motor from generating enough torque.
2. Low DC bus voltage – This can occur if supplied by an external DC source or during fast deceleration.
3. Mechanical load driving the motor – The load may be too heavy or moving in the opposite direction.
4. Drive requires autotuning – If the motor or its connections have changed, re-autotuning is needed.
5. Incorrect deceleration or ramp settings – Fast ramp times may not allow proper acceleration.

Check supply voltage, mechanical load, and ensure the drive is properly tuned to the motor.
