OverSpeedFault
Applies to: Servo Drive axes.
OverSpeedFault is a Boolean attribute. It is set when the speed of the axis, as determined from the feedback, has exceeded the overspeed limit, which is typically set to 150% of the motor’s configured velocity limit. An OverSpeedFault shuts down all axes associated with the drive.
OverSpeedFault is a recoverable condition.
To clear an OverSpeedFault:
- Fix the underlying cause of the fault: check for feedback phasing and overdriving load.
- Be sure your program or fault handling routine contains a Shutdown Reset (MASR or MGSR) instruction to return the axis to the ready operating state.
The occurrence of an OverSpeedFault on a Servo Drive axis sets bit #15 of the DriveFault attribute, the PhysicalAxisFault attribute, and bit #0 of the AxisFault attribute.
