only once.
1. Check that the motor running direction is correct.
2. Check that the motor running current is normal.
• 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.
5. Check that the slow-down switches and limit switches are effective.
3. Check that inspection on top of the car is enabled
.
4. Check that the shaft is unobstructed.
• During running at inspection speed, the current for motor no-load running is smaller than 1 A, 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:
• 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.
• 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 floor. It is recommended that the running time and distance be not
long each time, preventing over travel terminal or damage to the car.
• Check that the shaft is unobstructed without any obstacles, so that the car will not be damaged.
□ Whether the brake is released completely
□ Whether the elevator balance coefficient is normal
□ Whether the car or counterweight guide shoes are too tense
