PFN 15 / P33 Controlled Fault Stop Enable
LCD / LED
Displays
PFN: Ctrl Flt En
15 On
Range Off – On (Default: On)
Description A Controlled Fault Stop can occur if this parameter is “On”. If this parameter is on, the controller will brake the
motor before faulting when the Stop Mode (CFN05 / P10) is set to “Dyn brake”. If the Stop mode is set to
“Coast” then this parameter has no effect on the operation.
NOTE: Only certain faults can initiate a controlled fault stop. Some faults are considered too critical and
cause the controller to trip immediately regardless of the Controlled Fault Stop Enable parameter.
Refer to Appendix B - Fault Codes on Page 113 to determine if a fault may perform a controlled stop.

PFN: Pullout Mode
16 Fault Immed
Range Fault Immed (Default)
Retry
Ride Thru
Description The pullout mode selects the controllers response to a slipped pole. The controller can be set to either trip
immediately, try a number of resynchronization attempts, or attempt to ride through the situation. A
resynchronization attempt consists of removing the field for the delay time and then reapplying the field.
Fault Immed:
Immediately trips the controller on a loss of sync fault, if a slipped pole or pullout is detected.
Retry:
In this mode the controller will try to resynchronize the motor a maximum of the selected number (1 - 10) of
times. If a slipped pole is detected, the field will be removed. The system will wait the user selected Resync
Time (PFN 17 / P8), then resynchronization will be attempted. The controller will try the selected number of
Resync Tries (PFN 18 / P9), waiting the delay period in between each resynchronization attempt. If
resynchronization is not achieved after the selected number of attempts, the controller will fault on a Loss of
Sync fault.
Ride Thru:
If a slipped pole is detected, the system will keep the field applied. If resynchronization is NOT detected in the
user selected Resync Time (PFN 17 / P8), the controller will trip on a Loss of Sync fault.
