LS iS7

LS frequency inverter iS7 series is dependable because it has high performance and reliability.

Powerful electric current type sensorless vector control.
Our iS7 technology includes a competitive and strong low-speed torque control and a speed-precision-driven vector algorithm.
- Speed control range 100:1
- Extremely low torque control capability: 0.1Hz/150% real torque
- Max. torque control capability within the restoration range

Sensored vector realizing precise speed/torque control.
In the entire speed range including zero speed, powerful torque (more than 250%) performance is materialized through receiving Max. 200kHz frequency pulse via encoder-dedicated board. 
- Speed control range 1000:1 
- Instant Max. torque control capability 250% 
- 50Hz speed control response

Automatic torque balance droop control.
Droop control algorithm adjusts changeable torque driven by speed. This algorithm is easily applicable to open loop linking driving and load sharing driving.

LS drive iS7 series is flexible because it is easily expandable.
