| As demands for machine productivity increase, there is a growing interest in the use of fast-tool servos in motion control applications. These actuators have a very high bandwidth, but typically a very limited travel range. Examples include voice-coil motors, piezo crystals, laser galvanometers and magnetostrictive transducers.
Our latest application note describes Spectral Decomposition, a new strategy for pairing these fast tool servos with standard slow-tool servos. The result is a servo system that can deliver high-bandwidth performance without sacrificing range of travel.   |
