ACS Motion Control Introduces Smarter Motion Systems

MIGDAL HA’EMEK, Israel — ACS Motion Control, a leading international provider of advanced multi-axis motion and machine control solutions, has developed smart motion systems that decrease cycle times and increase throughput, all in a smaller, low footprint package. ACS’ advanced algorithms, designed specifically for handling highly demanding force control applications like wire bonding, limit impact forces and suppress induced vibrations to achieve maximal bandwidth and practically zero settling time to sub-micron resolution.

In wire bonding applications, after contact is detected, force is applied based on a pre-defined timing diagram, and the system switches back smoothly to ‘position’ mode. ACS’ advanced EtherCAT-based architecture enables a smooth transition from ‘position’ mode to ‘force’ mode and back within 50usec.

ACS’ intelligent systems feature motion profiles that operate at a real-time servo update rate (20kHz), providing dynamic performance that results in smooth, fast motions with durations as low as 100-500usec. The profile generation is superior to second- and third-order motion profiles in that it results in reduced drive current during aggressive moves, allowing for increased throughput.

“Our special algorithms generate advanced motion control functions that feature non-linear spring compensation, gravity compensation, and a damping mechanism to limit impact force and suppress induced vibrations. Through these advances, we minimize settling time, eliminate jitter, increase accuracy, and enhance the accuracy of the motion system,” said Ze’ev Kirshenboim, President of ACS Motion Control. “Wire bonding is a challenging application. ACS systems maximize throughput and provide the highest performance of any solution available in the market today.”

ACS’ EtherCAT®-based distributed control architecture creates custom solutions based on combinations of modular, scalable, standard product offerings. In a recent wirebonding application, ACS developed a control solution consisting of its SPiiPlusSC + UDMlc + UDMba units. The SPiiPlusSC (Soft Controller) is a state-of-the-art, PC-based, zero-footprint controller with support for up to 64 fully-coordinated axes and a 5kHz update rate. The UDMlc is a lower-power, low-footprint, high-performance, quad-axis drive and is used to power the bonding head axis. It also has the advantage of an extra (4th) axis, which can be used for an additional non-demanding, typically open-loop process (opening and closing a shutter, for example). The UDMba is a higher-power, high-performance, dual-axis drive and powers the XY stage.
