Cause : Pulse output overspeed comes when output pulse frequency exceeds frequency upper limit allowed by hardware.

Er.510 fault in inovance IS650 servo drive indicates Pulse output overspeed. This means output pulse frequency exceeds frequency upper limit.

1. Decrease H05-17(Encoder frequency- division pulses), making output pulse frequency below frequency upper limit allowed by hardware in the speed range required by mechanical condition.
2. Decrease input pulse frequency to within frequency upper limit allowed by hardware.
