ACS Motion Control has developed a compact universal drive interface module for traditional ±10V command servo drives.
The UDIhp Series (Universal Drive Interface high power) is designed to provide precise position and velocity control as part of a cost-effective, flexible & scalable EtherCAT network, replacing traditional ±10V motion controllers. The UDIhp Series meets the requirements of demanding, motion centric applications, such as high-precision positioning stages used in flat panel and wafer inspection.
Measuring 121 x 100 x 48 mm³ (4.8 x 3.9 x 1.9 in³), the UDIhp Series is an ultra-compact EtherCAT module that controls up to four motor drives with ±10V analog interface. It supports both torque commands with a single ±10V differential signal per axis, and sinusoidal commutation current commands with two ±10V differential signals per axis. The UDIhp Series includes four incremental encoder and two absolute encoder interfaces, safety limit inputs for each axis, four MARK high-speed encoder registration inputs, four 24Vdc/0.2A brake control outputs and one PEG (position event generator) high-speed position trigger output.
The UDIhp Series utilizes a 16-bit DAC to generate the ±10V commands, and supports fast analog SIN-COS encoders with raw signal frequencies up to 5MHz. This enables running stages using high-resolution laser encoders with sub-nanometer resolution at more than one meter per second.
The UDIhp can be used with any of the ACS SPiiPlus EtherCAT controllers, and is fully supported by the SPiiPlusNT Suite application development studio for drive configuration, axis tuning, and multi-axis application programming. The SPiiPlusNT Suite also includes a full PC-based controller simulator that greatly reduces the cost of ownership and time-to-market for OEMs, system integrators and end users.
