• 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.

Variable Frequency Drive (IP5A)
IP5A

• Dual PID
When additional PID control or Cascade PID control is required, Dual PID provides users various uses of the system with only iP5A.
• Multi Motor Control
The built-in algebra control function enables an inverter to control many motors without a controller so that user can take advantage of energy-saving and cost-down.
• Sleep and Wake-Up
The built-in energy saving function makes inverter stop automatically when the capacity is very low.
• Pre Heater
The pre heater function is built-in to prevent motor damage and inverter break-down caused from humidity.
• Flying Start
When the inverter drives many ventilators or when the fan in a big load system turns due to a natural convection, iP5A operates the motor by searching the motor speed automatically.
• Auto energy saving
iP5A provides the auto energy saving function by the optimal flux control which minimizes an energy loss caused by a change of the load.
• Improved Management from Instant Power-off and Power Dip Generation
During the power Dip or instant power-off, which is generated by lightening, ground fault and power-failure, loads still keep the mechanical energy and this energy flows back to inverter by regeneration. The power-failure guarantee time is extended by using this electrical character of inverter.
• Constant and Stable Performancel (24 hours 365 days)
Regardless of outside alteration such as input voltage variation by load change or weather effect, iP5A can handle moter and load with best performance.
• Safety Stop
When unexpected power-failure blocks power supply, inverter stops motor by using inertia energy of load that prevents unexpected second accident (Parameter setting is required).
