FR-A800-E

It is available if the CC-Link option of the FR-A8NC is installed. 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 >>

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 >>
