Functions
Multi-speed setting (up to 9 steps)?2-step acceleration/ deceleration, 2-step jump frequency, UP/DOWN selection, jog command…etc.
Full-range automatic torque boost, slip compensation, stall prevention, over torque detection, DC injection braking…etc.
Remote speed reference?0~10VDC, 4~20MA?0~20MA, multifunction input and output terminal, analog output monitor, NPN and PNP input signal switch
MODBUS message format, RS485 series communication card available (Optional accessory)
Built-in digital keypad operator (RCUS-450) with complex digital keypad operator (RCU-450) (Optional accessory)
Single Phase Power Input (some units)
Using single-phase power drives three-phase motor to rise the efficiency. Flow Machine(Fan-Pump)
Changing motor speed smoothly makes the best of flow to save energy. Food Processing Machine
The operation speed can be changed by using multi-speed functions (up to 9-step speed) and pre-set speed. Standard Mechanization
The machine controlled by the inverter/drive can be used with local power frequency (50/60 Hz).
