How can resolve problem ocA Over-current during acceleration fault in delta ME300 series Drive ?
Cause : Output current exceeds 2.5 times of the rated current during acceleration. When ocA occurs, the drive closes the gate of the output immediately, the motor runs freely, and the display shows an ocA error.
1. Increase the acceleration time
2. Increase the acceleration time of S-curve
3. Set auto-acceleration and auto-deceleration parameter (Pr.01-44)
4. Set over-current stall prevention function (Pr.06-03)
5. Replace the drive with a larger capacity model.
