Nikki Denso NPS-FI Series Servo Drive

NPS-FI series is the special servo driver for Induction type AC servomotors. Advantages of using induction type AC servomotors are: it controls the torque ripple around +/-4% to create smooth motor movement, the speed control range can be as low as 5000:1 of rated speed that is ultra slow, and torque can be steady within this range. Since it contains Field Control Circuit, it can over drive about 3 times faster than the rated motor speed, and the output can be steadily controlled.
