CommutationFault

Applies to: Servo Drive axes.
CommutationFault is a Boolean attribute. It is set when the commutation feedback source associated with the drive axis has a problem that prevents the drive from receiving accurate or reliable motor shaft information to perform commutation.
CommutationFault is a recoverable fault.
To clear a CommutationFault:
  1. Fix the underlying problem: either the connection or the device.
  2. Be sure your program or fault handling routine contains either a:
    • Fault Reset (MAFR) instruction, to clear all motion faults for an axis, or
    • Shutdown Reset (MASR or MGSR) instruction to return to the axis ready operating state.
The occurrence of an CommutationFault sets bit #22 of the DriveFault attribute, the PhysicalAxisFault attribute and bit #0 of the AxisFault attribute.
