Cause : Over slip error comes when the motor speed has deviated from the programmed speed limit by a certain amount for a specific duration.
The oSL fault in Delta MS300 drive indicates a Over slip error. This means the motor speed has reached the programmed speed limit set in the drive.
- When Pr.07-31=0 and when the drive outputs at constant speed, and F>H or F<H no longer exceeds the Pr.07-29 level, the oSL warning automatically clears.
- Check the motor parameter.
- Check the parameter settings for oSL protection.
