Servo Drive Module Works Like Linear Drive Without Drawbacks


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.

The NPMPM is a slave that runs under any ACS EtherCAT masters. The  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.
