Servo stepper drive is stepper drive with encoder input, it is similar as a AC servo drive. However, it’s cost is around 40% as AC servo.
IO type switch stepper drive is provided with the pulse train with S-shape acceleration/deceleration, and triggers the motor start-stop only by normal switching value. Compared with the speed-control motor, IO-type switch stepper motor is featured with stable start-stop and uniform speed, which can simplify the engineer’s electrical design.
