Cause : SW OverCurrent comes when drive output current has exceeded the 1 ms current rating. This rating is greater than the 3-second current rating and less than the hardware overcurrent fault level.
- It is typically 200…250% of the drive continuous rating.
- Check for excess load, improper DC boost setting.
- DC brake volts set too high.
- If enabled, check level of flux braking in parameter.
