AD800S VFD for PMSM (permanent magnet synchronous motor)

AD800S is enhanced VFD of AD800 high performance, which tailed made for permanent magnet synchronous motor, shares the same hardware of Ad800 VFD’s.

It can use to drive (PMSM) permanent magnet synchronous motori in 2 control modes, close loop vector control with encoder feedback, sensorless vector control without encoder.
