to top of pageFeatures:
* Full-range Automatic Torque Boost
o High starting torque (150%/ 3Hz) to start the machine smoothly.
* Complete Protective Functions
o High-speed current limit to prevent over current (200% or more of the rated current), tripless operation (Momentary power loss restart, stall prevention, fault reset)
o Built-in rush current limited circuit
o Ground fault protection
* Multiple Functions
o Multi-speed setting (up to 9 steps)?2-step acceleration/ deceleration, 2-step jump frequency, UP/DOWN selection, jog command…etc.
o Full-range automatic torque boost, slip compensation, stall prevention, over torque detection, DC injection braking…etc.
o Remote speed reference?0~10VDC, 4~20MA?0~20MA, multifunction input and output terminal, analog output monitor, NPN and PNP input signal switch
o MODBUS message format, RS485 series communication card available (Optional accessory)
o Built-in digital keypad operator (RCUS-450) with complex digital keypad operator (RCU-450) (Optional accessory)
* Broad Application
o Substitute Magnetic Contact
No contact ensures, no transmission and maintenance requested.
o Conveyer
Soft start/stop function enables goods to stand still on conveyer.
o Single Phase Power Input
Using single-phase power drives three-phase motor to rise the efficiency.
o Flow Machine(Fan/Pump)
Changing motor speed smoothly makes the best of flow to save energy.
o Food Processing Machine
The operation speed can be changed by using multi-speed functions (up to 9-step speed) and pre-set speed.
o Standard Mechanization
The machine controlled by the inverter/drive can be used with local power frequency (50/60 Hz).
