The UDI (UDI - Universal Drive Interface) is a compact EtherCAT module that controls up to 4 motor drives with industry standard ±10V interface. Now you can also use peizo-ceramic motor drives and linear drives when using any of ACS EtherCAT motion controllers, to achieve the ultimate position and velocity accuracy as required by demanding applications, such as wafer inspection. It supports both single torque command and two sinusoidal commutation current commands. It includes 4 incremental encoders (digital and SIN-COS), and 2 absolute encoders, four registration inputs, four 24Vdc/0.2A motor brake outputs and one PEG (Position Event Generator) output.

The UDI is available in two versions: UDIHP a high performance version and UDILT economical version. The UDlLT utilizes a 10 bit DAC to generate the ±10V commands and supports digital encoders only, incremental and absolute. The UDlHP utilizes a 16 bit DAC supports also SIN-COS encoders with raw frequencies up to 5MHz. This enables controlling positioning stages using high resolution laser encoders with sub-nanometer resolution at more than 1 meter/second. For PC based systems that utilize motor drives with analog ±10V commands, the combination of the SPiiPlusSC and the UDI is a superior solution when compared to solutions that are based on a PC plug-in controller. It is simpler, more powerful, scalable, and provides better performance at a lower cost. The UDI is panel or din rail mountable.
