control in different ways: stepping motor controller: by controlling the pulse number control rotation Angle, a pulse interval Angle corresponding to a. Servo motor controller: through controlling the length of the pulse time control rotation Angle different workflow: stepping motor controller: the work flow for stepper motor general controller work requires two pulses, pulse signal pulse and direction. Servo motor controller, its working process is a switch power supply connection, then connect the servo motor controller. Low frequency characteristics of different: stepper motor controller: low frequency vibration phenomenon is seen at low speeds. Servo motor controller: running smoothly, even in the low speed also won't appear when the vibration phenomenon. Stepper motor controller, the output torque increases with speed decreases, and at a high speed when they fell sharply, so its maximum working speed is in commonly 300 ~ 600 r/min. Servo motor controller: for constant force torque output, namely in the rated speed (General is 2000 or 3000 r/min)Less than, rated output torque, in for a constant power output above the rated speed. Overload capacity is different: stepper motor controller: do not generally have overload ability. Servo motor controller: has the strong ability of overload.
