The following is a comprehensive list of detected drive faults. Listed after each fault is a
description of what the fault is, and a suggested corrective action.
Fault
Analog to digital convertor on
AtoD Fault
control board not responding.
Brake hold state does not
Brk Hold Fault
match the commanded state.
Brk IGBT Fault Brake IGBT overcurrent.
Brake pick state does not
Brk Pick Fault
match the commanded state.
Charge Fault DC Bus has not charged.
Contactor state does not
Contactor Fault
match the commanded state.
The drive parameters are
Cube Data Fault
The drive identification is
Cube ID Fault
Actual current does not match
Curr Reg Fault

Units
This parameter displays the measured flux producing current.
This parameter displays the measured torque producing current.
This parameter displays the flux voltage reference.
This parameter displays the torque voltage reference.
Ohms This parameter displays the calculated base impedance.
This parameter displays the estimated no load current of the motor.
This parameter displays the estimated rated RPM of the motor.
Description
Cycle power to controller and see if fault clears. If not, replace Control
board.
Disabled on O. Thompson Controls.
An overcurrent of the braking IGBT has occurred. Fault latches, but does
not shut the car down until it stops to allow passengers to safely get off
the car. Confirm that the motor data is correctly entered into the drive, that
the braking resistance at TB1+3 and TB1 +4 is connected and sized
correctly, and that the car is balanced correctly.
Disabled on O. Thompson Controls.
The DC Bus has not reached the desired stabilized voltage level within 2
seconds
The drive has turned on the command to close the Main Contactor and the
Contactor Confirm signal at TB1-9 is not present for the amount of time
specified by the "Contact Flt Time" parameter.
Check all drive parameters. Cycle power to the drive. If fault re-occurs,
invalid. replace Control board.
Cycle power to the drive. If fault re-occurs replace Control board.
invalid.
Check motor connections and motor windings for open circuit. Check
main contactor for bad contact. If OK, bad current sensor or bad drive
unit.
Check all drive parameters. Cycle power to the drive. If fault re-occurs,
set correctly. replace Control board.
Check motor connections, main contactor contacts and motor windings.
Make sure the brake is lifting. Verify that the encoder is properly
