Lincoln elevator always stops on the first floor.

I suddenly felt the elevator start. What caused it?

1. Improper adjustment of low-speed PI leads to elevator retrogression, resulting in sudden feeling.

2. Please increase the P at zero speed or low speed. When the I unit of the frequency converter is time, reduce the I value of the zero speed section or the low speed section. When the unit of frequency converter I is the reciprocal of time, increase the I value of zero-speed section or low-speed section to improve the sensitivity of system response.

3. Inappropriate startup timing can also cause sudden feelings.

4. It is observed that if the elevator starts with a brake, which leads to sudden feeling, please increase the main board parameter F58 to make the speed curve come out later; If the elevator starts to slip, resulting in sudden feeling, please increase the parameter F 16 to output the brake later.

5. Improper setting of motor parameters will also cause starting shock.

6. If the slip of motor parameters and no-load current are set improperly, it will have a certain impact on the start of the elevator. If you have the conditions for autonomous learning, please do dynamic word learning.

7. Too tight boots can also cause a sense of starting. Please adjust the guide shoes properly.

8. In the case of preload, if the load compensation is not properly adjusted, it will also cause a sense of starting. Please adjust the weighing device.

9. Improper setting of analog offset will also lead to non-zero speed startup, resulting in a sudden feeling.

10. The guide boots are too tight.

The elevator stopped suddenly. What caused it?

1. When the elevator stops, it will slip, which will cause a sense of shock; The phenomenon of parking and slipping is generally caused by the direction of frequency converter.

The signal was withdrawn early, the brake was not reliably closed, and there was no current in the motor, resulting in a slight slip. Please increase the value of motherboard parameter F 17 (excluding direction delay) to prolong the delay time of activation and direction after the brake is turned on.

2. When parking, the speed has not reached zero. If you step on the brakes with speed, you will feel scared. Please increase the value of the motherboard parameter F59 (zero-speed braking delay) so that after the elevator reaches zero speed, there is enough delay before braking;

3. Improper setting of analog bias will also lead to braking with speed when parking, resulting in sudden feeling;

4. If the crawling speed is set too high, it will also cause a sense of stagnation when parking.

5. Too tight guide shoes will also cause poor parking comfort.

6. The door knife touches the door lock and stops.

7. If the brake clearance is too large, there will be an emergency stop.
