Controller Overtemp
Cutback
1. Controller is performance-limited at this temperature.
2. Controller is operating in an extreme environment.
3. Excessive load on vehicle.
4. Improper mounting of controller.
5. See 1311 menu Monitor » Controller: Temperature.
1. Normal operation. Fault shows that the 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. See 1311 menu Monitor » Battery: Capacitor Voltage.
7. Blown B+ fuse or main contactor did not close.
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 1311 menu Monitor » Battery: Capacitor Voltage.
1. External load impedance on the +5V supply (pin 26) is too low.
2. See 1311 menu Monitor » outputs: 5 Volts and Ext Supply Current.
Digital Out 6
Overcurrent
1. External load impedance on Digital Output 6 driver (pin 19) is too low.
Digital Out 7
Overcurrent
1. External load impedance on Digital Output 7 driver (pin 20) is too low.
1. Motor temperature is at or above the programmed Temperature Hot
setting, and the requested current is being cut back.
2. Motor Temperature Control Menu parameters are mis-tuned.
3. See 1311 menus Monitor » Motor: Temperature and Monitor » Inputs:
Analog2.
4. If the application doesn’t use a motor thermistor, Temp Compensation
and Temp Cutback should be programmed Off.
1. Motor thermistor is not connected properly.
2. If the application doesn’t use a motor thermistor, Temp Compensation
and Temp Cutback should be programmed Off.
3. See 1311 menus Monitor » Motor: Temperature and Monitor » Inputs:
