1,2 drives, 12-100v, up to 13.3/40A
100V/40A, PCB Mounted NanoPWMTM 1 / 2 Axis EtherCATTM Drive Module
The Ultimate Drive for The Most Demanding
Powerful and Compact
Better Than Linear Drives
Uncompromising speed and resolution
Smart Motion related I/O
The NPMPC Is a line of the most advanced PWM servo drives available today.
It is specifically designed to address the most demanding applications with regards to move and settle times,
standstill jitter, and velocity smoothness, such as wafer metrology and inspection, FPD inspection, and ultra-precision
machining for processing of optical components. The NPMPC is based on the ACS proprietary technology
that exceeds stand still jitter and tracking error performance that until now has been achieved only with linear drives,
with reduced cost of ownership.
With the optional combination of a 10MHz laser encoder interface and the powerful algorithm, demanding
sub-nanometer resolution positioning systems can achieve ultimate throughput and accuracy with minimal sensitivity
to disturbances and stage to stage manufacturing differences.
The NPMPC is designed to be mounted on a custom carrier board. It enables customizing connectors, I/O configuration,
STO and other safety function implementation.
For prototype testing and carrier board design reference it is recommended to use the NPMPM.
The NPMPC is a slave that runs under any ACS EtherCAT masters.
A comprehensive set of software support tools are provided for module configuration, setup and tuning.
