The UDMSD is a series of compact EtherCAT modules with dual/quad-axis universal drives for servo, step, and voice coil motors with a continuous power range of 10W to 100W (200W peak).The unit is powered by a 12 to 48Vdc drive supply voltage and by a separate 24Vdc ±20% control supply that keeps all logic signals alive during emergency conditions.It is available with currents of 1.25/2.5A and 2.5/5A (cont./peak).

The type of motor is selected by the user and can be set differently for each drive without any hardware change. The UDMSD supports four digital incremental and two absolute encoders.

Small size, low weight, and minimal cable interface makes the UDMSD ideal for mounting remotely on moving axes. It includes a Serial Peripheral Interface (SPI) to support other feedback devices, such as autofocus signals.

All connectors of the motors, the encoders and the I/Os are sub-D type connectors. The unit is supplied with the drive and control connectors.
