Schneider inverter commissioning procedure

1. Type recognition: Whether the type of frequency converter is common with the type of frequency converter purchased.

2. Transportation admission: After opening the package, check whether the frequency converter is damaged during transportation.

3. Voltage recognition: the field power supply voltage should be within the voltage range of the frequency converter. Otherwise, all the following steps stop.

4, step mechanical installation

5. Insulation measurement of motor and frequency converter: Then connect the frequency converter: connect the motor line to T1, T2 and T3 according to the drawing to ensure the connection and voltage are common; Connect the main power supply to R, S, T after ensuring that the power supply is closed: connect the control source: connect the speed of the given source. A connecting network with a network.

6. Power-on debugging and speech correction: speech selection will be displayed after power-on. (Only power on ** need to do this correction)

7. Restore factory Settings

8. Access level correction

9, set motor parameters: motor power, voltage, current, frequency, speed, and so on, and self-setting

10. Set acceleration and deceleration time: set a reasonable acceleration and deceleration time

11. Set maintenance parameters: thermal maintenance current value of the motor, current limiting value, etc.

12. Set the control source and frequency source: set the channel for starting the frequency converter in instruction 1.6, and the channel with the given frequency. Set ** high frequency, ** low frequency, etc.

13, the distribution of application function application function: such as braking logic control.

14. Confirm the steering of the motor: given the minimum frequency, point the inverter to recognize the steering of the motor; If contrary, parameter PHr in 1.4 can be corrected.

15. Record the current value of several frequency segments
