There are several methods for changing the direction of a motor using a frequency converter, including the following:
1. Change the phase sequence of the motor wiring: By changing any two phases of the three-phase wiring U, V, and W of the motor, the motor direction can be quickly changed. This method is suitable for situations where a frequency converter is not used.
2. Set the parameters of the frequency converter: Each frequency converter has corresponding "forward and reverse rotation parameters", and users can modify the corresponding parameters (such as changing "0" to "1") by consulting relevant manuals or searching online to change the forward and reverse rotation of the motor.
3. External terminal wiring swap: The external terminal block of the frequency converter usually has ports such as "FWD" and "REV" or "M0" and "M1". By adjusting the wiring of these terminals, forward and reverse switching can be achieved.
Attention:
·During the adjustment process, ensure that the load on the motor is within the allowable range to avoid overheating or damage.
·Pay close attention to the operation of the motor, such as temperature and noise, and immediately stop adjusting and inspecting the equipment if any abnormal situations are found.
·After modifying the parameters of the frequency converter, it should be ensured that the parameter settings are correct, and actual operation can only be carried out after successful load testing.
