Oriental Motor's AlphaStep closed loop control systems perform accurate positioning operations with ease. The AlphaStep features a unique control system combining the benefits of ''open loop control'' and ''closed loop control''.
With the AlphaStep control system, the position of the motor is always monitored and then the driver automatically switches between the two types of control depending on the situation. Under normal circumstances the operation of the motor is monitored and control is applied using open loop like a standard stepper motor. If an error occurs between the command and motor position due to a load or the like, the system immediately switches to closed loop control like a servo motor. This corrects the position and speed maintaining the desired operation. The combination of these two control methods ensures high reliability and performance.
