To meet the demanding requirements of motion control applications in industrial automation and satisfy the needs of high-precision positioning control requested by machine designers and system integrators, Delta launched the high-performance motion control ASDA-A2 series servo motors and servo drives in 2009. The 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. Stable rotation at low speed has also been achieved.
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 sufficiently.
Built-in automatic high-frequency resonance suppression: two auto notch filters are provided to suppress the mechanical resonance automatically.
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 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.
Smooth interpolation between points can be completed automatically to yield a flexible programming.
