Motor characteristics at low input voltage

Since the dedicated motor is designed with the rated voltage of approximately 320 V, it can produce sufficient torque for the input voltage of 380 V. Therefo... More Details >>

Optimum excitation control

For the FR-F800 series, in addition to the conventional Optimum excitation control, Advanced optimum excitation control with the improved starting torque is ... 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 >>

Inverter installation interchange attachment

Use the FR-A5AT02 as the intercompatibility attachment when upgrading from the FR-A220-3.7K to FR-A540-3.7K. More Details >>

Coasting operation of the inverter
