Delta AC Servo Drive & Motor ASDA-A3 Series

As the market of automated manufacturing rapidly develops, the need for servo products with higher performance, speed, precision, bandwidth, and functionality is widely increasing. To meet the requirements of the motion control market for industrial manufacturing machines, Delta presents a new High-end AC Servo System, the ASDA-A3 Series, with features such as multi-functionality, high-performance, energy-efficiency, and compact design.

With auto-tuning and a user-friendly interface for system analysis, the ASDA-A3 Series provides 3.1kHz of bandwidth and employs a 24-bit absolute type encoder, creating advantages that include high response, precise locating, and stable and flexible performance. In addition, the series has added new functions such as vibration suppression, system diagnosis, and a shared DC-bus design which can regenerate energy. Delta’s AC Servo System ASDA-A3 Series offers a comprehensive technology and solution to help our customers enhance their machine’s precision and achieve excellent performance.

Description

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 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

► Backward compatibility design for motor to meet future replacement
► ASDA-A3 drive can support both A2 (ECMA)
and A3 (ECM-A3) series motors

► To ensure the positioning accuracy at the end and eliminate the effect of transmission backlash, full-closed loop control function is
an effective solution
