Usage

1. Changing frequency to 0 Hz(1) Set Pr.8 (Deceleration time) to 0 second.If the load is large, the stall prevention function may work to lengthen decelerati... More Details >>

0 Hz output of inverter

When the command frequency is 0 Hz, the inverter does not generate output and the voltage is 0 V. More Details >>

Alarm output signal when using CC-Link

The RX7 output signal is the same as the signals for NO, NC, and transfer contact output.You can change the contents of this output signal using Pr.192.Pr.19... More Details >>

When controlling motor with brake by inverter

Use the RUN signal to turn ON and OFF the brake.Using the MRS (output shutoff) signal to turn ON the brake shuts off the inverter's output and reduces influe... More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>
