Walk and lift controller fault code
Code Fault name Possible cause
1
Controller Over
current
1, motor external U,V or W connection short circuit
2. Motor parameters do not match
3. The controller is faulty
2
Current Sensor Fault
1, motor U, V, W through the stator on the car body short circuit,
resulting in leakage
2. The controller is faulty
3
Precharge Failed 1. Negative load is connected to the positive end of the capacitor, so
that the capacitor can not be charged normally
4
Controller Severe
Under temp 1The operating environment of the controller is too harsh
5
Controller Severe
Over temp 1. The working environment of the controller is too harsh
2. Vehicle overload
3. The controller is incorrectly installed
6
Severe Under voltage 1. Battery parameters are incorrectly set
2. Power consumption of non-controller system
3, the battery impedance is too large
4. The battery is disconnected
5, the fuse is disconnected, or the main contactor is not connected
7
Severe Over voltage 1. Battery parameters are incorrectly set
2. The battery impedance is too high
3. Battery connection is disconnected during regenerative braking
8
Controller Under temp
Cutback 1. The controller works under restricted conditions
2, the controller working environment is harsh
9
Controller Over temp
Cutback 1, the controller working environment is harsh
2. Vehicle overload
3. The controller is incorrectly installed
10
Under voltage Cutback 1. The battery is low
2. Battery parameters are incorrectly set
3. Non-controller system runs out of power
4. Excessive battery impedance
5. The battery is disconnected
6. Fuse is disconnected or main Contactor is disconnected
11
Over voltage Cutback 1, regenerative braking process regenerative system
The running current causes the battery voltage to rise
2. Battery parameters are incorrectly set
3, the battery impedance is too large
4. Battery connection is disconnected during regenerative braking
12
+5V Supply Failure 1, the external load impedance is too low
13
Digital Out 6 Failure 1, the external load impedance is too low
14
Digital Out 7
Over current 1, the external load impedance is too low
