53 Backward coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil
for short circuit or open circuit.
54 Lifting error of lifting coil: Check the connection of the coil and confirm that it is normal. If normal, check the
coil for short circuit or open circuit.
55 Lifting error of lowering coil: Check the connection of the coil and confirm that it is normal. If normal, check
the coil for short circuit or open circuit.
56 Right turn coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil
for short circuit or open circuit.
57 Left turn coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil for
short circuit or open circuit.
58 Brake coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil for
short circuit or open circuit.
61 Cool down the machine, and check the wiring. If the wiring is OK, replace the motor controller
62 Restart the machine, if fault exists, check the root cause; if fault still exists, replace the motor controller
63 Check the wiring, and then restart it, and replace the motor controller if necessary
64 Check whether the motor parameter enable delay is too short, and confirm that the parameter is correct
65 Check the wiring, and ensure that the correct throttle type is selected in the motor controller
66 Ensure that the emergency reverse check parameter in the motor controller is set to off
67 The motor enable delay may be too short, and confirm that parameter of other motor controllers is correct
68 Low voltage error: Check the battery voltage and charge if necessary. Check connection between the
battery and the switch, reinforce or clean it. Check whether the voltage of the PCU and the ECU is normal.
69 MC is detecting current in the motor, but there shall be no current in this case. MC thinks that the brake is
turned on
70 Adjust the ZAPI and/or check the toggle voltage due to loose wiring
71 Check the wiring of the main contactor, and replace the contactor or the motor controller if necessary
72 Check the battery voltage, check if it is charging. If the fault still exists, try to replace the motor controller
73 Cool down the restart machine or replace the motor controller
74 Check the wiring of the motor or replace the motor controller
75 Check the wiring of the pump motor, restart the machine or replace the motor controller
76 Check the wiring of the left drive motor, restart the machine or replace the motor controller
77 Check the wiring of the motor, restart the machine or replace the motor controller
78 Check the wiring of the pump motor, restart the machine or replace the motor controller
79 Check the motor connection and ensure that they are tightened, and check the motor for short circuit
80 Alarm of exceeding 80% load: As the platform is close to the load limit, it is not recommended to increase
the load.
81 Check the motor connection and ensure that they are tightened, and check the motor for short circuit
82 Check the connection of the coil terminal and ensure that they are tightened, and check whether the coil is
connected properly
