● Advantages over Open-loop Control Stepping Driver
   1. Reliable positioning without loss of synchronism.
   2.Holding stable positino and automatically recovering to the original position even after experiencing positioning error

due to a external force, such as mechanical vibration.
   3.Ezi-SERVO covers 100% full range of the rated torque, contrary to a conventional open-loop stepping driver that can use

only up to 50% of the rated torque by considering loss of synchronism.
   4.Capability to operate at high speed owing to a load-dependant current control, whereas open-loop drivers use a constant

current control at all speed range without considering load variations.

● Advantages over servo motor controller
   1.No gain tuning(Automatic adjustment of gain in response to a load change.)
   2.Maintain the stable holding position without fluctuation after completing positioning.
   3.Possible to fast positioning owing to the independent control by on-board DSP.
   4.Favorable continuous operation at short-stroke rapid movement process thanks to short positioning time.
