0X22 Controller
Overtemperature
Cutback
0X23 Undervoltage Cutback
0X24 Overvoltage Cutback
POSSIBLE CAUSES
1. Controller is operating in an
extreme environment.
2. Excessive load on vehicle.
3. Improper mounting of controller
which is preventing controller
cooling.
4. Controller is performance-limited
at this temperature.
5. See Programmer » System
Monitor menu » Controller:
Temperature.
1. Batteries need recharging.
Controller is performance limited at
this voltage.
2. Battery parameters are
misadjusted.
3. Non-controller system-drain on
battery.
4. Battery resistance too high.
5. Battery disconnected while
driving.
6. Blown B+ fuse or main contactor
did not close.
7. See Programmer » System
Monitor menu » Controller »
Currents » UnderVoltageCutback.
8. See Programmer » System
Monitor menu » Controller »
Capacitor Voltage.
1. Normal operation. Fault shows
that regen braking currents elevated
the battery voltage during regen
braking. Controller is performance
limited at this voltage.
2. Battery parameters are
misadjusted.
3. Battery resistance too high for
given regen current.
4. Battery disconnected while regen
braking.
5. See Programmer » System

SET/CLEAR CONDITIONS
Set: Controller's Heatsink
temperature exceeded 85 °C.
Clear: Bring heatsink tempera-
ture below 85 °C.
Set: Capacitor bank voltage
dropped below the
UnderVoltageCutback limit
with the FET bridge enabled.
Clear: Bring the capacitor
voltage above the controller's
UnderVoltageCutback limit.
Set: The controller's capacitor
bank voltage exceeded the
OverVoltageCutback limit with
the FET bridge enabled.
Clear: Bring controller's
capacitor voltage below the
OverVoltageCutback limit.
