ACS Motion Control recently expanded its NanoPWM line of PWM (pulse width modulation) servo drives to include a new dual axis EtherCAT drive. The NPMpm Series of EtherCAT servo drive modules are designed to provide motion performance previously only achievable using linear drives, without the drawbacks of such linear drives.

When utilized with the optional 10MHz laser encoder interface and the ServoBoost control algorithm, positioning systems can achieve speeds above 2m/s, sub-nanometer jitter values, nanometer velocity tracking errors, low settling time, and system robustness with minimal sensitivity to disturbances and load changes. 

“Based on ACS Motion Control's proprietary and unique NanoPWM technology, the NPMpm Series is specifically designed to address the most demanding applications with regards to move & settle times, standstill jitter and velocity smoothness,” said Ze'ev Kirshenboim, ACS Motion Control president. “Recently, the NanoPWM drives have been tested by the Fraunhofer Institute for Production Technology (Fraunhofer-Institut für Produktionstechnologie) IPT in Germany, and achieved standstill jitter and step response results that are better than any other drives that this institute has tested so far.”

The NPMpm is a slave that runs under any ACS EtherCAT masters. The NanoPWM drives have already been used in wafer metrology & inspection, FPD inspection, and ultra-precision machining for processing of optical components.
