2. Main Characteristics

Ezi-SERVO automatically controls motor current according

to load. Ezi-SERVO reduces motor current when motor

load is low and increases motor current when load is

high. By optimizing the motor current, motor heat can

be minimized and energy can be saved.

Heat Reduction / Energy Saving

(Motor Current Control according to load)

1

Ezi-SERVO is an innovative Closed Loop System that

utilizes a high-resolution motor mounted encoder

constantly to monitor the current position. The encoder

feedback allows the Ezi-SERVO to update the current

position every 25 μs e c . It allows the Ezi-SERVO drive to

compensate 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 but Ezi-SERVO automatically correct the position

by encoder feedback.

Closed Loop System

To ensure machine performance, smoothness, positional

error and low servo noise, conventional servo systems

require the adjustment of its servo’s gains as an initial

crucial step. Even systems that employ auto-tuning

require manual tuning after the system is installed,

especially if more that one axis are interdependent.

Ezi-SERVO employs the best characteristics of stepper,

closed loop motion controls and algorithms to eliminate

the need of tedious gain tuning required for conventional

closed loop servo systems. This means that Ezi-SERVO

is optimized for the application and ready to work right

out of the box. The Ezi-SERVO system employs the

unique characteristics of the closed loop stepping motor

control, eliminating these cumbersome steps and giving

the engineer a high performance servo system without

wasting setup time. Ezi-SERVO is especially well suited

for low stiffness loads (for example, a belt and pulley

system) that sometime require conventional

servo systems to inertia match

with the additional expensive

and bulky gearbox.

Ezi-SERVO also performs

exceptionally, even under

heavy loads and high

speeds.

2

No Gain Tuning

www.fastech-motions.com - 7

Traditional servo motor drives overshoot their position

and try to correct overshooting by moving the opposite

direction, especially in high gain applications. This is

called null hunt and is especially prevalent in systems

that the break away or static friction is significantly

higher than the running friction. The cure is lowering

the gain, which affects accuracy or using Ezi-SERVO

Motion Control System. Ezi-SERVO utilizes the unique

characteristics of stepping motors and locks itself

into the desired target position, eliminating Null Hunt.

This feature is especially useful in applications such

as nanotech manufacturing, semiconductor fabrication,

vision systems and ink jet printing in which system

oscillation and vibration could be a problem.

Ezi-SERVO boosts the voltage supplied to the motor

to increase the torque at high speed. In the case that

motor speed is increased, Back-EMF will be increased

accordingly and it cause the reduction of motor torque

at high speed. Since Ezi-SERVO has the function to

increase the voltage supplied to the motor to compensate

the torque reduction, the torque of motor at high speed

can be imrpoved about 30%.

※ The torque at high speed is improved about 30%

Similar to conventional stepping motors, Ezi-SERVO

instantly synchronizes with command pulses providing

fast positional response. Ezi-SERVO is the optimum

choice when zero-speed stability and rapid motions

within a short distance are required. Traditional servo

motor systems have a natural delay called settling time

between the command input signals and the resultant

motion because of the constant monitoring of the current

position.

Ezi-SERVO is a high-precision servo drive, using a

high-resolution encoder with 32,000 pulses/revolution.

Unlike a conventional Microstep drive, the on-board

high performance MCU (Micro Controller Unit) performs

vector control and filtering, producing a smooth rotational

control with minimum ripples.

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.

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.

High Speed

Compared with common step motors and drives, Ezi-

SERVO motion control systems can maintain a high torque

state over relatively long period of time. This means

that Ezi-SERVO continuously operates without loss of

position under 100% of the load. Unlike conventional

Microstep drives, Ezi-SERVO exploits continuous high

torque operation during high speed motion due to its

innovative optimum current phase control.
