SFD Sensor Failure
SFD UART Error
SFD Communication Error
Option Card Watch Dog
Time Out
Position Error Too Large
Option Card Fault
Internal SFD failure.
Excessive electrical noise in the drive environment
causing communications interference.
Internal SFD failure.
Feedback cable not connected at the drive or at the
motor.
Feedback cable shield not connected.
Defective feedback cable.
Internal SFD failure.
Excessive electrical noise in the drive environment
causing communications interference.
Communication error between option card and main board.
Check ExtFaults:
ExtFaults = Step size over flow means
GearOut/GearIn is too large.
ExtFaults = Position error over flow means that the
following error, = PosErr, has exceeded ±128 revs.
Check if the motor is stalling or if the commanded speed is
higher than the motor can achieve at the present bus voltage.
Check ExtFaults:
If ExtFaults is AuxFBFault, then the AusFB device is in error.
Check the AuxFB faults: AuxFBEnDatFlt, AuxFBPTCFit, or
AuxFBSCDFlt.
Check to make sure the the drive is set up for the correct
feedback device and that the device is functioning
correctly. If ExtFaults is "No Extended Fault", then this was a
fault induced by the controller, such as SynqLost.
