New Dual Axis EtherCAT® PWM Servo Drive Module From ACS Delivers Sub-Nanometer Performance
ACS Motion Control has expanded its NanoPWM™ line of ground breaking PWM (pulse width modulation) servo drives to include a new dual axis EtherCAT drive. The NPMPM Series of EtherCAT servo drive modules provide motion performance that was previously only achievable using linear drives, without the drawbacks of such linear drives. The NPMpm drives are significantly smaller, much more efficient, produce less heat dissipation, better protected and lower in cost.
“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 Fraaunhofer 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™ type of drives have already been proven successfully in the most demanding applications of wafer metrology & inspection, FPD inspection, and ultra-precision machining for processing of optical components.
