ACS3-CAPW13XX*4

Cutting-edge Specifications

3.1 kHz Bandwidth

► Higher responsiveness and shorter settling time could increase productivity

24-bit Absolute Type Encoder

► The positioning precision is enhanced by

the 16,777,216 pulses/turn encoder

► The speed variance in low speed is reduced

► Absolute type encoder keeps motor's

position when power is off

High speed motor with 6,000 r/min  and 350 % peak torque 

► A3 motor can accelerate and decelerate

faster with its design

► This specification is available for motor frame

size 40 mm, 60 mm and 80mm

Motor with high or low inertia rotor

► For application requiring stable rotating speed and better

disturbance resistant capability, a high inertia motor is

more suitable, such as machine tools

► For application like reciprocating motion and fast

positioning request, a low inertia motor can be used,

such as electronic manufacturing machines

Low Cogging Torque Motor

► Cogging torque of the ECM-A3 motor

is only 1.5% of the rated torque, which

brings smoother operating speed and

increases the stability when machining

at low speed

Supports a Variety of Servo Motors

► Backward compatibility design for motor to meet

future replacement

► ASDA-A3 drive can support both A2 (ECMA)

and A3 (ECM-A3) series motors

Full-Closed Loop Control

► To ensure the positioning accuracy at the

end and eliminate the effect of transmission

backlash, full-closed loop control function is

an effective solution

System Tuning and Safety Functions

System Diagnosis Function

► The rigidity of a machine is known through a

mathematical model

► The consistency of the machine's batch installation

can be checked

► By comparing the data from different time span, the

wear condition of a machine can be acquired

Low Frequency Vibration Suppression Function

► Vibration elimination algorithm is different from command filter and used as a creative algorithm on

ASDA-A3

► The vibration can be eliminated without slowing down its response

► In addition to vibration elimination algorithm, the two command filters for low frequency vibration are

included

Auto-Tuning Function

► Lower the barrier for users to use

servo systems

► This function will optimize the machine

performance with less tuning effort

► It can be done via panel keypad or

software

Advanced Notch Filter

► There are 5 sets of notch filters with tunable

bandwidth and up to 5000Hz band for ASDA-A3

► Those filters can search resonance and set the

attenuation level automatically

► With shorter search time for resonance, the

machine is less likely to be damaged

Safe Torque Off (STO) Function *note : to be certified

► Built-in STO (Safe Torque Off) function

► The motor power will be cut-off when STO is activated

Motion Inside

► 99 sophisticated motion commands and segments

allowed

► Arithmetic operation and condition jump commands

are added

► Graphical user interface offers simple setup and

programming

► General motion functions like homing, position and

speed commands are available

► Superimposition, blending and on-the-fly change

motion commands are provided

Built-in Camming Functions

► E-CAM functions for flying shear and rotary

cut are well configured

► There are maximum 720 points in one cam

profile or contour with interpolation smooth

algorithm

► Useful E-CAM phase secure and adjustment

functions are easy to apply

► Many successful applications from ASDA-A2

are available for reference

Capture and Compare Functions

► Only 5µs response time to latch the position or pulse count after receiving the activated DI single.

► The high-speed DO will response when assigned position or count value is reached after 5µs

response time

Energy-Saving and Compact Size Design

DC-bus Sharing Feature

► The regenerative energy will be collected

to DC-bus for other axes to increase

energy efficiency

► Smaller resistor installed is possible for

the system, which can save cost and

installation space

Thinner Size Servo Drive

► ASDA-A3 is 20% smaller than A2 on dimensions,

which requires less installation space

Smaller Size Servo Motor

► ASDA-A3 series servo motor is 20% shorter than A2's

User-Friendly Software

Tree-View Index Window

► Well organized list and collapsible menu help

to access functions easily

Graphical Interface for Parameter

Settings

► Intuitive user interface provides set up

functions and parameters without manual

findings

Auto-Tuning Wizard for Gains

► Provides step by step guiding wizard for users to tune a servo

Advanced Gain Tuning Interface

► The servo gains can be easily fine-tuned for

better performance with its well-designed

tuning modes

Product Information

Servo Motor Features

The ECM-A3 Series AC Servo Motor is a high-precision permanent magnet AC servo motor. It can

be used with the ASDA-A3 AC Servo Drives of 200 ~ 230V with power ranging from 50W ~ 750W.

Motor frame sizes offer 40 mm, 60 mm and 80 mm. Two motor models are available, the ECM-A3H

high inertia and the ECM-A3L low inertia which rated speed is 3000 r/min and the Max. speed is 6000

r/min. The max. torque of the ECM-A3H is 0.557 N-m ~ 8.36 N-m and that of ECN-A3L is 0.557 N-m ~

8.36 N-m.

The high precision permanent magnet AC servo motor ECMC Series can also be applied with the

ASDA-A3 220 V Series AC Servo Drive with power range from 850W ~ 3kW. The available frame sizes

are 100 mm, 130 mm, and 180 mm. Selectable rated torque are 1000 r/min, 2000 r/min, and 3000 r/m

while the max. speed is 3000 r/min and 5000 r/min. And the max. torque is from 9.54 N-m to 57.3 N-m.

The ECM-A3 and the ECMC Series AC Servo Motors provide optional devices, brakes and oil seals, as

well as two shaft types: round shaft and keyway.
