1. The control cabinet, the main engine, and the brake connection line are correct, and the voltage is correct;

2. Safety circuit, door lock circuit is normal, limit switch, speed change switch and close;

3. The connection cable from the encoder to the PG card must be reliable and accurate;

4. Admit that after the brake is opened, the elevator will not slip (able to lift the car or balance the load state);

5. Adjust the parameters of the inverter: A04=1 (acquiesce to 1, which should be the same as the parameter setting of the motherboard);

B11=1 (the speed of the main engine is less than 100, it must be set to 1);

　　C02=0；

　　C13=1；

　　E01=1；

E02=number of poles;

E03=Rated voltage;

E04=rated speed;

E05=rated current;

E09=0 (tacitly Heidenhain 1387) encoder type;

E10=2048;(Other parameters do not need to be changed, keep the factory value)

6. Set A03=4, and then give the control cabinet maintenance signal, the control system will give the inverter direction signal, enable the signal;

If the D1 and D2 lights of the inverter operator are on, and the monitoring U14 parameters are monitored, it is necessary to increase, otherwise the V and W phases of the inverter output are replaced;

If the D1 and D3 lights of the inverter operator are on, and the U14 parameters are monitored, it is necessary to reduce, otherwise replace the V, W phase of the inverter output;

If there is no change in the U14 parameters, check whether the brake is opened, or whether the voltage is not enough to maintain the voltage of the brake after the brake is released;

7. After the tuning is completed, A03=3, the position of the encoder after tuning is in U15, repeat 6 three to four times, if the parameters after tuning are within -10......+10, then set A03 to 0;

8. If the main engine rotates normally and the setting is completed.
