SP9007 SSPA:07 Overspeed
The motor speed has exceeded 115% of its rated speed. When the spindle axis was in position control mode, positional deviations were accumulated excessively (SFR and SRV were turned off during spindle synchronization). Check for a sequence error (for example, check whether spindle synchronization was specified when the spindle could not be turned).
Quick tip:
Check for sequence error
