How can I have the motor coast to stop?

You can use the following two methods:1. Turn ON MRS at the same time when STF turns OFF.2. Set Pr.10 = 60 Hz, Pr.11 = 0 sec, and Pr.12 = 0% (when the invert... More Details >>

Meaning of OL display (2)

Yes. "OL" is displayed under speed control whenever the torque limit is reached without regard to the rated torque. More Details >>

Noise from motor at low speed

It is considered to be caused by inverter PWM control. It can be suppressed by raising the PWM carrier frequency (Pr.72), but the entire noise and leakage cu... More Details >>

Speed setting

The high speed command (multi-speed command) is prioritized over the frequency setting potentiometer. It is OK if these are both input simultaneously. When t... More Details >>

Frequency setting signal

Check the AU signal (AU - SD). To use the terminal 4, the AU signal (AU - SD) needs to be turned ON. Turning ON the AU signal (AU - SD) disables the terminal 2. More Details >>

4 to 20 mA output

Yes. It is available by using the FR-A7AY (plug-in option). By setting Pr.307 (Setting for zero analog output) to "20" and Pr.309 (Analog output signal volta... More Details >>
