FR-A800

No, they do not. Pr.72 is invalid at the offline auto tuning. It is also invalid when the motor rotates with Pr.96 = 101. More Details >>

Terminal response time

It is 2 to 3 ms. By setting Pr.289 Inverter output terminal filter and Pr.699 Input terminal filter, the FR-A700 can be compatible with the response of the t... More Details >>

Carrier frequency automatic reducing function

The function operates immediately when the current of 85% or higher flows. The limit is canceled when the current becomes 80% or lower. More Details >>

Reduced impact restart

Until now the DC has been applied to perform the frequency search. When Pr.162 = 3 or 13, the impact is reduced by detecting the phase and performing the sea... More Details >>

Residual voltage at the output shutoff

The rotation speed has almost no effect. The residual voltage increases when the torque boost is increased, but no adjustment is required. More Details >>
