Name	Description	Troubleshooting	Filter time before activation1
Tracking error	Drive stopped due to position or velocity tracking error getting larger than configured limit (Position tracking error thresholdFPT or Velocity tracking error thresholdFVT)	Check settings, operating conditions and fault limits to resolve.	Goal faults filter timeFFT
Over velocity	Motor has exceeded the speed limit defined at Over speed faultFEV		Goal faults filter timeFFT
Hardware	Drive internal error has occurred	Possibly external interference (check wiring and EMI suppression) and stability of logic supply voltage. If problem stays, contact Granite Devices support.	None
Over temperature	Drive temperature has exceeded its maximum value		None
Feedback	Failure in feedback device has been detected		None
Over current	Measured current was exceeding the limit value (current spike)	Check wiring or try different Over current toleranceFOC value	Affected by Over current toleranceFOC
Internal comm error	Drive internal error has occurred	Possibly external interference (check wiring and EMI suppression) and stability of logic supply voltage. If problem stays, contact Granite Devices support.	None
Power stage forced off	True when some of the fault states is forcing power stage off to protect drive. Motor is freely spinning unless braked mechanically.		None
Under voltage	HV DC bus voltage below Under voltage fault thresholdFUV value	Check voltage, parameters and safe torque off	None
Over voltage	HV DC bus voltage above Over voltage fault thresholdFOV value	Check voltage and Over voltage fault thresholdFOV. If happens during motor deceleration, then a braking resistor is needed.	None
Motion range	Motor has been commanded outside the allowed travel boundary. I.e. driven to limit switch when Limit switch functionLFS is set to fault stop		None
Firmware error	Drive internal error has occurred	Possibly external interference (check wiring and EMI suppression) and stability of logic supply voltage. If problem stays, contact Granite Devices support.	None
Init	Initialization failed. Possible reasons: drive disabled or faulted during initialization or initialization time-outed	Check enable signal, parameters, wiring and faults	None
Motion	Motor stall or loss of feedback signal detected	Adjust Motion fault thresholdFMO to larger value or disable	Goal faults filter timeFFT
SimpleMotion	SimpleMotion V2 Communication error detected, possibly connection lost, invalid parameter value is sent or transfer error caused by EMI or bad wiring		None
Configuration	Fault caused by invalid or unstable configuration parameters	Refer to Fault location number for pin-pointing the fault source	None
Fault location ID	See Fault location

1) The time duration that drive will allow fault condition be true before fault status is latched. Some faults have user adjustable time delay to reduce error sensitivity in dynamic conditions, such as rapid acceleration.
