ACS Motion Control is proud to introduce its advanced Force Control algorithm

Developed and refined to address the needs of high-precision and high-throughput force control applications:

• Hybrid bonding
• TC (thermo-compression) bonding
• Die bonding
• LED bonding
• Wire bonding
• Wafer probing and test
• Silicon Photonics assembly and test
• Electronics assembly and test

Solving Real-World Challenges

ACS’ Force Control algorithm solves common, difficult challenges faced by OEM machine builder motion control engineering teams:

• Instantaneously detecting contact and transition smoothly from position/encoder control mode to force control mode (soft landing)
• Settling to target force immediately after contact (e.g. within several ms)
• For high throughput applications, performing high acceleration moves (e.g. > 10 G) while minimizing excitation of system resonances
• For high precision applications, achieving high resolution force control (e.g. +/- 0.01 N)

Feature Highlights

Engineered for performance and flexibility, Force Control from ACS offers a variety of features and advantages:

• Supported by multiple high-performance ACS servo drive models: UDMsa/sm/nt/lc, MDMst
• Real-time control algorithm execution on the servo drive at 20 kHz (higher control rate and lower latency than over-the-network-based schemes)
• Up to 16-bit force sensor input (drive model dependent)
• Use with advanced profile generation algorithms to minimize vibration
• Optimize closed-loop control bandwidth with FRF Analyzer
• User-defined force profiles
• Configurable contact detection methods
• Force sensor signal calibration
• Suitable for open-loop and closed-loop use cases
• Suitable for voice coil stages, linear motor stages
