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
