LS Inverter iS7 Series

 


















iS7 generates 
a more powerful performance
through its superior V/F control, V/F PG, slip
compensation, sensorless vector control, and
PMSM ( Permanent Magnetic Synchronous Motor ).
The iS7 focuses on a user-friendly interface and
environment-friendly feature including a wide
graphic LCD keypad, user & macro group support,
electro-thermal functions for motor protection, and
protection for input/output phase loss.
