iC5 Drive

High torque micro VFD

Small capacity and high performance LS inverter iC5 series.

iC5 provides satisfies various customer needs with Modbus, PID control, Sensorless

vector control, Auto Tuning, etc.



  • Sensorless vector control
    The iC5 adopts sensorless vector control algorithm, and it improves not only the torque control characteristics, but the speed controlability in an uncertain condition caused by the load variation as well.
  • Auto Tuning
    The auto tuning algorithm in the iC5 sets the motor factors automatically that brings the traditional commissioning difficulties mainly in low speed by the load variation and the low torque generation to a settlement.
  • Highly efficient DSP chip
    The iC5 adopts highly efficient DSP(Digital Signal Processing) chip to improve processing speed, flexibility, stability and etc.
  • PNP, NPN Dual Control Signal
    The iC5 provides PNP and NPN signals for outside controllers.
    It works with 24Vdc regardless of the type of PLC or control signals.
  • Communication interface, Modbus-RTU
    The iC5 provides the most popular communication interface, ModBus-RTU for remote control by PLC
    or other devices.
  • PID Control
    PID process control is used in iC5 to make speed corrections quickly with a minimal amount of overshoot
    and oscillation for the control of flow, temperature, pressure and etc.
