Dual axis EtherCAT PWM drive delivers sub-nanometer performance

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

The NPMPM is a slave that runs under any ACS EtherCAT masters. The NanoPWM types of drives have already been proven successful in the most demanding applications of wafer metrology and inspection, FPD inspection, and ultra-precision machining for processing of optical components.

“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, President, ACS Motion Control. “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.”
