Load characteristics fault detection

It is based on the motor rated torque. More Details >>

FR-A800

Yes. When Pr.9 = 0, turning is performed with the inverter rated current. Always set the rated motor current. 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 >>

FR-A800

Yes, they are. More Details >>

Cumulative pulse monitor

The count is resumed from 0. Thus, the times of the overflow is reset. More Details >>

Carrier frequency automatic reducing ...

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 >>

Frequency search

DC application method (Pr.162 = 0 or 10): 4 Hz or lower is regarded as 0 Hz. AC application method (Pr.162 = 3 or 13): It is not defined since it depends on ... 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 >>

PLC function

Vector control: The SM1217 turns ON when the motor rotates even if no forward rotation command is send. Other than vector control: The SM1217 turn ON by forw... More Details >>
