MOTOR FAULT CODES (4 OF 8)
POSSIBLE CAUSE
1. Motor phase is open.
2. Bad crimps or faulty wiring.
1. Main contactor tips are welded closed.
2. Motor phase U or V is disconnected or
open.
3. An alternate voltage path (such as an
external precharge resistor) is providing
a current to the capacitor bank (B+
connection terminal).
1. Main contactor did not close.
2. Main contactor tips are oxidized, burned,
or not making good contact.*
3. External load on capacitor bank (B+
connection terminal) that prevents
capacitor bank from charging.
4. Blown B+ fuse.
1. See Monitor menu » Inputs: Throttle Pot.
2. Throttle pot wiper voltage too high.
1. See Monitor menu » Inputs: Throttle Pot.
2. Throttle pot wiper voltage too low.
1. See Monitor menu » Inputs: Pot2 Raw.
2. Pot2 wiper voltage too high.
1. See Monitor menu » Inputs: Pot2 Raw.
2. Pot2 wiper voltage too low.
1. See Monitor menu » Outputs: Pot Low.
2. Combined pot resistance connected to
pot low is too low.
1. Failure to write to EEPROM memory.
This can be caused by EEPROM memory
writes initiated by VCL, by the CAN
bus, by adjusting parameters with the
programmer, or by loading new software
into the controller.
TROUBLESHOOTING
SET / CLEAR CONDITIONS
Set: Motor phase U, V, or W detected open.
Clear: Cycle KSI.
Set: Just prior to the main contactor closing, the
capacitor bank voltage (B+ connection terminal)
was loaded for a short time and the voltage did not
discharge.
Clear: Cycle KSI
Set: With the main contactor commanded closed,
the capacitor bank voltage (B+ connection terminal)
did not charge to B+.
Clear: Cycle KSI.
*New contactors may need to be cycled electrically &
mechanically to remove any non-conductive material on
the tips. Use reduced voltage (e.g., 12V) to prevent tip
damage through excessive arcing.
Set: Throttle pot wiper (pin 16) voltage is higher
than the high fault threshold (can be changed with
the VCL function Setup_Pot_Faults()).
Clear: Bring throttle pot wiper voltage below the
fault threshold.
Set: Throttle pot wiper (pin 16) voltage is lower than
the low fault threshold (can be changed with the
VCL function Setup_Pot_Faults()).
Clear: Bring throttle pot wiper voltage above the
fault threshold.
Set: Pot2 wiper (pin 17) voltage is higher than the
high fault threshold (can be changed with the VCL
function Setup_Pot_Faults()).
Clear: Bring Pot2 wiper voltage below the fault
threshold.
Set: Pot2 wiper (pin 17) voltage is lower than the
low fault threshold (can be changed with the VCL
function Setup_Pot_Faults()).
Clear: Bring Pot2 wiper voltage above the fault
threshold.
Set: Pot low (pin 18) current exceeds 10 mA.
Clear: Clear pot low overcurrent condition and cycle
KSI.
Set: Controller operating system tried to write to
EEPROM memory and failed.
Clear: Download the correct software (OS) and
matching parameter default settings into the
controller and cycle KSI.
