1, e 0 1- inverter unit protection. Cause: The output of the main loop is grounded or short-circuited; Traction machine connecting line is too long; The working environment is overheated; The internal wiring of the controller is loose.

2.E02— Accelerated overcurrent. Cause: The output of the main loop is grounded or short-circuited; Whether the motor parameters are adjusted; The load is too heavy.

3. E03-deceleration overcurrent. Cause: The output of the main loop is grounded or short-circuited; Whether the motor parameters are adjusted; Excessive load; The deceleration curve is too steep.

4.E04— Constant-speed overcurrent. Cause: The output of the main loop is grounded or short-circuited; Whether the motor parameters are adjusted; Excessive load; The code disk has great interference.

5.E05— Accelerated overvoltage. Cause: the input voltage is too high; Elevator braking device is abnormal; The acceleration curve is too steep.

6.E06— Retarding overvoltage. Cause: the input voltage is too high; Brake resistance is too large; Or the brake unit is abnormal; The deceleration curve is too steep.

7.E07— Constant-speed overvoltage. Cause: the input voltage is too high; Excessive braking resistance or abnormal braking unit. ?

8.E08— Control power failure. Cause: the input voltage is too high; The driving control panel is abnormal. ?

9.E09— Undervoltage fault. Cause: the input power supply was cut off instantly; The input voltage is too low; The driving control panel is abnormal.

10, e10-system overload. Cause: abnormal brake holding circuit; The load is too heavy.

1 1, e 1 1- motor overload. Reason: improper setting of FC-02; Brake circuit is abnormal; The load is too heavy.

12, e12-input phase loss. Cause: unbalanced input power supply; The driving control panel is abnormal.

13, E 13— Output is out of phase. Cause: the output wiring of the main circuit is loose; The motor is damaged. ?

14, e14-module overheating. Cause: The ambient temperature is too high; The fan is broken or the pipe is blocked.

15, E 15— reserved.

Code troubleshooting:

Check the surface of the power cord for damage and short circuit to ground.

Check whether there is copper wire grounding on the motor side terminal.

Check the motor for short circuit or grounding.

Check whether the star seal contactor causes short circuit to the inverter output.

Check whether the motor parameters are consistent with the nameplate.

Re-learn motor parameters.

Before reporting the fault, check whether the brake continues to open.

Check for mechanical blockage.

Check whether the balance coefficient is correct.
