PowerPhaseLossFault

Applies to: Servo Drive axes.
PowerPhaseLossFault is a Boolean attribute. It is set when the drive detects that one or more of the three power line phases is lost from the three phase power inputs. A PowerPhaseLossFault shuts down all axes associated with the drive.
PowerPhaseLossFault is an unrecoverable condition.
To clear a PowerPhaseLossFault:
  1. Fix the underlying cause of the fault (blown fuse, open contactor, grounded phase, etc.).
  2. Execute a Fault Reset (MAFR) instruction, to clear all motion faults for an axis.
The occurrence of an PowerPhaseLossFault on a Servo Drive axis sets bit #26 of the DriveFault attribute, the PhysicalAxisFault attribute, and bit #0 of the AxisFault attribute.
