High Speed
The Ezi-SERVO operates well at high speed without the
loss of synchronism or positioning error. Ezi-SERVO' s
ability of continuous current position monitoring of
enables the stepping motor to generate high torque,
even under a 100% load condition.
● Advantages over Open-Loop Control Stepping Drive
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.
● Advantages over Servo Motor Controller
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.
