  • 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.
