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

 

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.

 

Kinetic Energy Buffering (KEB)
for a stable system stop in case of power loss or failure Ride-through (LV trip delay) for sudden power loss

 

iS7 offers options with flexibility and expendability.

Built-in Built in RS485 & Modbus-RTU communication
 Profibus-DP, DeviceNet, LonWorks options
 Expandable I/O options: Max. input 11 points, Max. output 6 points
