AF-3100α AF3104-055 Sumitomo Inverter

        Description:

• The AF-3100α is a general-purpose high performance inverter used for controlling the speed of a 3-phase induction motor.
• The AF3100α provides high-precision speed control from ultra-low to high speed in sensorless vector mode. The AF3100α can provide control to +/-0.2% with a speed range of 120:1 (maximum  60Hz). Speed control as precise as a DC motor control is possible in sensorless vector operation. 
• An important feature in the complete control of the AF3100α is allowed in three separate modes: Sensorless Vector, Volts/Hertz and Vector Control (closed loop using Pulse Generator Feedback) 
• In addition, high torque at low speed with sensorless vector control selected allows for a maximum of 200% torque and can be obtained over the 120:1 speed range. This is comparable to DC control. The starting torque capacity is a maximum of 250%.
