High precision control in the industry
– ECMA series Servo Motors feature incremental encoder with 20-bit resolution (1280000 pulses/revolution).
Existing functions to meet the requirements from delicate process have been enhanced and stable rotation
at low speed has also been achieved.
– Absolute type encoder is supported. Homing position will not get lost when power is cut off.
(External battery case for absolute encoder is easy to install and use.)
– The external battery power is 4.5VDC.
Note: Servo motors with absolute encoders are under development.
 Outstanding response characteristic
– 1kHz frequency response.
– Settling time below 1ms.
– 10ms acceleration time from -3000r/min to 3000r/min when running without load.
 Superior vibration suppression for wide variety of applications
– Built-in automatic low-frequency vibration suppression (for crane control): two vibration
suppression filters are provided to minimize the vibration at machine edges automatically and
– Built-in automatic high-frequency resonance suppression: two auto notch filters are provided to
suppress the mechanical resonance automatically.
– Resonance points can be monitored upon FFT (Fast Fourier Transform) function of ASDA-A2-
Soft tuning software so as to complete the suppression more precisely.
 Full closed-loop control (Capable of reading second feedback signals)
– Built-in position feedback interface (CN5) is able to read second feedback signals from motor encoder and send the
current position back to the drive to form a full closed-loop control system so that high accuracy position control can be accomplished.
– Reduce the effects of mechanical imperfections such as backlash and flexibility to ensure the
position precision at machine edges.
 Flexible internal position procedure mode (Pr mode)
– ASDA-A2-Soft tuning software provides internal parameter editing function for the users to define
the path of each axis freely.
– Pr mode offers 64 internal positions for continuous motion control.
– Destination position, speed and acceleration & deceleration command could be changed in the
middle of operation.
– 35 kinds of homing modes are available.
 Unique built-in electronic cam (E-CAM) function
– Up to 720 E-CAM points.
– Smooth interpolation between points can be completed automatically to yield a flexible
– ASDA-A2-Soft tuning software provides electronic cam (E-CAM) profile editing function.
– Applicable for rotary cut-off and flying shear applications.
 Real-time Capture and Compare functions
– Capture function for high-speed pulses
* Capable of capturing the instant position coordinate of the motion axis, Response time is 5μs.
* Suitable for digital color mark sensor applications.
– Compare function for high-speed pulses
* Capable of reaching preset position coordinate of motion axis and output pulses instantly,
Response time is 5μs.
* Applicable for the applications of industrial CCD camera.
 Fieldbus network communication (Support CANopen protocol)
– Complies with CANopen DS301 standard–CAN bus communication speed is 1M bps.
– 3 CAN motion modes (Profile Position Mode, Interpolation Position Mode, Homing Mode) are
provided for CANopen DS402 implementation.
– Station configuration can be set via parameter settings.
– In conjunction with Delta’s PLC able to save on wiring and establish Delta fieldbus system
 Compact and slim design
– Overall width is 40% thinner than ASDA-A series.
– Compact size for side by side installation, requiring minimal space between units in a small
enclosure (2mm).
 Versatile expandability
– Extension port at right side of the servo drive is for connecting a variety of options to extend the
functionality and meet the requirements of various applications.
 User-friendly communication interface
– USB (type B) port is equipped as standard for fast and direct connection to PC.
– Enhanced monitoring speed up to 1Mbps.
