2. Main Characteristics

1

Integrated Solution

Ezi-SERVOⅡ BT with integrated Motor and Encoder

and Drive has provides the optimum solution that

can take full advantage of Ezi-SERVOⅡ by realizing

compact size and simple wiring.

2

Closed Loop System

Ezi-SERVOⅡ 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-SERVOⅡ to update the current

position every 50 μs e c . It allows the Ezi-SERVOⅡ

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-SERVOⅡ automatically correct the

position by encoder feedback.

3

No Gain Tuning

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-

SERVOⅡ 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-SERVOⅡ

is optimized for the application and ready to work right

out of the box. The Ezi-SERVOⅡ 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-SERVOⅡ 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-SERVOⅡ also performs

exceptionally, even under

heavy loads and high

speeds.

Heat Reduction / Energy Saving

Ezi-SERVOⅡ automatically controls motor current

according to load.

Ezi-SERVOⅡ 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.

(Motor Current Control according to load)

※ The torque at low speed is improved about 30%.

Measured Condition : Drive = Ezi-SERVOⅡ-BT-42L

Torque Improvement

Ezi-SERVOⅡ can increase the motor current up to 150%

by setting the Run Current by parameter. Therefore

acceleration and deceleration characteristics and torque

characteristics at low speed can be increased.

Ezi-SERVOⅡ can improve the torque in the low speed

range by about 30%.

No Hunting

Traditional servo motor drives overshoot their position

and try to correct by overshooting 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-SERVOⅡ Motion Control

System. Ezi-SERVOⅡ 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.

7

Smooth and Accurate

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

high-resolution encoder with 20,000 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.

8

Fast Response

Similar to conventional stepping motors, Ezi-SERVOⅡ

instantly synchronizes with command pulses providing

fast positional response. Ezi-SERVOⅡ 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.

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.

10

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.

10. Specifications of Motor with Brake

* Brake Operation Timing Chart

Ezi-SERVOⅡ-BT-56/60/60 series control Brake by Drive automatically.

Please refer to below Timing Chart when control Brake from upper controller other than using

Ezi-SERVOⅡ-BT-56/60/60 series Brake control.

Otherwise, Drive malfunctioning and loads can be fall down.

Also, please do not operate Brake while motor operation to prevent damage.

Ezi-SERVOⅡ-BT-28 series has no brake control function.

＊ The code of encoder resolution will be marked in“■”

＊ Electronic Brake cannot be used for braking. Position hold purpose only when power OFF.

＊ The weight means Motor Unit Weight including Motor and Electronic Brake.

＊ Motor specification and torque characteristic are same as Standard Motor.
