1. Ensure that the control cabinet, main unit, and brake connection cables are correctly connected and the voltage is stable.

2. Verify that the safety circuit and door lock circuit are functioning properly, and that the limit switch and speed change switch are closed.

3. Confirm that the cable from the encoder to the PG card is securely and accurately connected.

4. After confirming that the brake is released, ensure the elevator does not slip (you can lift the car or balance the load).

5. Adjust the inverter parameters as follows: - A04 = 1 (default value, must match the motherboard settings) - B11 = 1 (set the host speed to 1 when below 100) - C02 = 0 - C13 = 1 - E01 = 1 - E02 = number of poles - E03 = rated voltage - E04 = rated speed - E05 = rated current - E09 = 0 (default is HEIDENHAIN 1387 for encoder type) - E10 = 2048 (other parameters should remain at factory settings)

6. Set A03 = 4, then check the signal sent to the control cabinet. The control system will provide the inverter with direction and enable signals. - If D1 and D2 lights on the inverter operator are on, monitor U14 parameters; it should increase. Otherwise, swap the V and W phases of the inverter output. - If D1 and D3 lights are on, monitor U14 parameters; it should decrease. Otherwise, swap the V and W phases. - If no change in U14 occurs, check if the brake is fully open or if the voltage is insufficient to maintain the brake.

7. After setting, set A03 = 3. The encoder position after tuning will be in U15. Repeat steps 6 through 4 times. If the parameter remains within -10 to +10, set A03 to 0.

8. Perform a test run. If the main unit rotates smoothly, the setup is complete.

Integrated Setting

1. Ensure the control cabinet, main unit, and brake connection cables are correctly connected and the voltage is stable.

2. Check that the safety circuit and door lock circuit are working properly, and that the limit switch and speed change switch are closed.

3. Make sure the encoder-to-PG card cable is secure and accurate.

4. After confirming the brake is open, ensure the elevator doesn't slip (you can lift the car or balance the load).

5. Adjust the inverter parameters: - F205 = 0 - F216 = 1 - F218 = 1 - F219 = number of poles - F220 = rated voltage - F07/F221 = rated speed - F222 = rated current - F226 = 0 (default is HEIDENHAIN 1387 for encoder type) - F227 = 2048 (keep other parameters at factory settings)

6. Navigate to the motor self-learning menu on the operator and press once. The control panel will send a signal, and the system will automatically start the learning process.

7. After completion, set F202 = 3. The encoder position after tuning will be in F228. Repeat step 6 three to four times. If the parameter is within -10 to +10, set F202 to 0.

8. Run a test. If the main unit operates smoothly, the setup is complete.
