For the asynchronous motor, there is no prompt during auto-tuning, but E33 is reported during
running at inspection speed.
To solve the problem, exchange any two of the motor cables (exchange only once). Then,
perform auto-tuning again.

Running Test at Inspection Speed
Function Code Parameter Name Setting Range Default
F2-10 Elevator running direction
0: Direction unchanged
1: Direction reversed
0
F3-11 Inspection speed 0.100–0.630 m/s 0.250 m/s
1. Check that the motor running direction is correct.
After auto-tuning is completed successfully, perform trial running at inspection speed to check
whether the actual motor direction is the same as the command direction. If not, change F2-10 to
correct the direction.
2. Check that the motor running current is normal.
During running at inspection speed, the current for motor no-load running is much smaller than the
rated motor current, and the actual current during with-load constant-speed running is not larger than
the rated motor current. If after multiple times of auto-tuning, the encoder angle deviation is small but
the current during with-load constant-speed running is larger than the rated motor current, check:
a. Whether the brake is released completely
b. Whether the elevator balance coefîš¿cient is normal
c. Whether the car or counterweight guide shoes are too tense
3. Check that car top inspection is enabled and inspection in equipment room is disabled. That
is, inspection on top of the car takes precedence over inspection in the equipment room.
4. Check that the shaft is unobstructed without any obstacles, so that the car will not be
damaged.
5. Check that the slow-down switches and limit switches are effective and pay special attention
to safety when you run the car to the terminal oor. It is recommended that the running time
and distance be not long each time, preventing over travel terminal or damage to the car.
