Frequency converter wiring method

The main circuit wiring of the inverter: (R, S, T) is the power input, and the inverter output terminals (U, V, W) are respectively connected to the motor.

If the control circuit is to rotate the motor normally, use an intermediate relay to connect the two points, the control contact input to the common terminal and the forward rotation start to the normally open contact of the intermediate relay. When the intermediate relay is energized, the motor rotates forward. Loss of power, the motor stops.

Inverter parameter setting: Common parameters include inverter frequency setting, running operation, maximum frequency, basic frequency, rated voltage, maximum output voltage, acceleration time, deceleration time, DC braking start frequency, DC braking time, starting Frequency value, start frequency hold time, stop frequency, data protection, function code description, LCE monitoring, reverse rotation inhibition, thermal relay operation current, etc. Just follow the inverter settings of different manufacturers and ok.
