Troubleshooting Chapter 6
26 Brake Slipped Alarm 1 The encoder movement has exceeded the level in P1110 [Brk Slip
Count] after the brake was set and the brake slip maneuver is
controlling the drive. (Drive is active.) Cycle power to the drive to
reset.
Alarm 2 The encoder movement has exceeded the level in P1110 [Brk Slip
Count] after the brake was set and the brake slip maneuver is finished.
(Drive is stopped.) Cycle power to the drive to reset.
27 Torq Prove Cflct Alarm 2 When P1100 [Trq Prove Cfg] is enabled, these parameters must be
properly configured:
• P35 [Motor Ctrl Mode]
• P125 [Pri Vel Fdbk Sel] and P135 [Mtr Psn Fdbk Sel] must be set to
a valid feedback device. The feedback device does not have to be
the same device. However, Open Loop and Simulation Feedback
are not considered valid feedback devices.
If parameters 125 and 135 are set to a feedback module, verify
that the module parameters are set properly. On the module, the
feedback loss action CANNOT be set to 0 “Ignore.” Does not work in
PM FV mode. Does not work with single ended or channel A only
encoders.
28 TP Encls Config Alarm 2 Encoderless TorqProve has been enabled but the application concerns
of encoderless operation have not read and understood. Read the
“Attention” on page 356 relating to the use of TorqProve with no
encoder.
29 Analog In Loss Configurable 263
[Anlg In0 LssActn] Analog input has a lost signal.
33 AuRsts Exhausted Resettable Fault Coast 348
[Auto Rstrt Tries] The drive attempted to reset a fault and resume running for the
programmed number of tries, unsuccessfully.
35 IPM OverCurrent Resettable Fault Coast The current magnitude has exceeded the trip level set by P1640 [IPM
Max Cur]. Set this value to 0 only when the drive is set to the V/Hz or
SVC mode.
36 SW OverCurrent Resettable Fault Coast Y The drive output current has exceeded the 1 ms current rating. This
rating is greater than the 3 second current rating and less than the
hardware overcurrent fault level. It is typically 200…250% of the
drive continuous rating.

Phase U to Grnd
Phase V to Grnd
Phase W to Grnd
Resettable Fault Coast A phase to ground fault has been detected between the drive and
motor in this phase.
Rotate U/T1, V/T2, W/T3 connections.
• If the problem follows the wire, suspect a field wiring problem.
• If no change, suspect a problem with the drive.

Phase UV Short
Phase VW Short
Phase WU Short
Resettable Fault Coast Excessive current has been detected between these two output
terminals.
Rotate U/T1, V/T2, W/T3 connections.
• If the problem follows the wire, suspect a field wiring problem.
• If no change, suspect a problem with the drive.

Phase WNegToGrnd
Resettable Fault Coast A phase to ground fault has been detected between the drive and
motor in this phase.
Rotate U/T1, V/T2, W/T3 connections.
• If the problem follows the wire, suspect a field wiring problem.
• If no change, suspect a problem with the drive.
48 System Defaulted Resettable Fault Coast The drive was commanded to write default values.
49 Drive Powerup – A Power Up Marker in the Fault Queue indicating that the drive power
cycled.
51 Clr Fault Queue – Indication that the fault queue has been cleared.
55 Ctrl Bd Overtemp Resettable Fault Coast The temperature sensor on the main control board detected excessive
heat. See product temperature requirement.
58 Module Defaulted Resettable Fault Coast The module was commanded to write default values.
59 Invalid Code Resettable Fault Coast Internal error.
61 Shear Pin 1 Configurable 435
[Shear Pin 1 Actn] Y The programmed value in P436 [Shear Pin1 Level] has been exceeded.
62 Shear Pin 2 Configurable 438
[Shear Pin 2 Actn] Y The programmed value in P439 [Shear Pin2 Level] has been exceeded.
