Ezi-SERVO®
Closed Loop Stepping Motor Drive System
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® utilizes100% 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-dependant current control, open-loop stepper
drivers use a constant current control at all speed ranges without considering load variations.
Advantages over Servo Motor Controller
1. No gain tuning (Automatic adjustment of gain in response to a load change.)
2. Maintains the stable holding position without oscillation after completing positioning.
3. Fast positioning due to the independent control by on-board DSP.
4. Continuous operation during rapid short-stroke movement due to instantaneous positioning.
creating a posi-tioning error and a great deal of cost to the end user!
* CLOSED LOOP SYSTEM
Ezi-SERVO® is an innovative closed loop stepping motor and controller that utilizes
a high-resolution motor mounted encoder to constantly monitor the motor shaft position.
The encoder feedback feature allows the Ezi-SERVO® to update the current motor
shaft position information every 25 micro seconds. This allows the Ezi-SERVO® drive to
compen-sate for the loss of position, ensuring accurate positioning. For example, due to
a sudden load change, a conventional stepper motor and drive could lose a step
♦ Ezi-SERVO® BT
Innovative integrated stepping motor and drive system in one robust package!
A high resolution encoder updates the motor position every 25 micro-seconds to the
integrated drive. Optimizing high performance DSP technology(Digital Signal Processor)
and proprietary software, the drive ensures exact position, no overshooting and smooth
motion at 100% of load.
