Terminal indicator lamp

The inverter outputs the peak voltage 300 to 400 VDC of the bus voltage not in a pure sine wave but a in a PWM waveform. Check if the lamp to be connected ca... More Details >>

Reverse rotation prevention selection

Yes, it does. When the inverter is coasting in the reverse direction, it starts in the reverse direction and switches to the forward rotation after a deceler... More Details >>

Frequency setting

Adjust the terminal 2 bias with Pr.C2 and Pr.C3, and the terminal 2 gain with Pr.125 and Pr.C4. Set Pr.C2 (Terminal 2 frequency setting bias frequency) to 20... More Details >>

Wire length between inverter and motor
