High Speed
The Ezi-SERVOⅡ operates well at high speed
without the loss of synchronism or positioning error.
Ezi-SERVOⅡ’
s ability of continuous current position
monitoring of enables the stepping motor to generate
high torque, even under a 100% load condition.

High Torque
Compared with common step motors and drives, Ezi-
SERVOⅡ motion control systems can maintain a high
torque state over relatively long period of time. This means
that Ezi-SERVOⅡ continuously operates without loss of
position under 100% of the load. Unlike conventional
Microstep drives, Ezi-SERVOⅡ exploits continuous high
torque operation during high speed motion due to its
innovative optimum current phase control.
1. Reliable positioning without loss of synchronism.
2. Holding stable position and automatically recovering to the original position even after experiencing positioning error
due to external forces, such as mechanical vibration or vertical positional holding.
3. Ezi-SERVO utilizes 100% of the full range of rated motor torque, contrary to a conventional open-loop stepping driver
that can use up to 50% of the rated motor torque due to the loss of synchronism.
4. Capability to operate at high speed due to load-dependent current control, open-loop stepping drivers use
a constant current control at all speed ranges without considering load variations.
1. No gain tuning. (Automatic gain adjustment in response to a load change)
2. Maintains the stable holding position without oscillation after completion of positioning.
3. Fast positioning due to the independent control by on-board MCU.
4. Continuous operation during rapid short-stroke movement due to instantaneous positioning.
