ACS' New Compact EtherCAT Drive Module for Applications with Limited Space

UDMSD Series EtherCAT module with dual/quad-axis universal drives for small servo, step, and voice coil motors...

BLOOMINGTON, MN – ACS Motion Control has launched a new series of compact EtherCAT drive modules for servo, step, and voice coil motors. Featuring a powerful dual/quad-axis universal drive, the UDMSD Series is designed for motors with a continuous power range of 10W to 100W (200W peak). The type of motor is selected by the user and can be set differently for each drive.

The UDMSD Series addresses the needs of demanding multi-axis motion applications with limited space, such as moving inspection heads, small manipulators, moving coil actuators, and table-top motion stages.

The small size, low weight, and minimal cable interface makes the UDMSD Series ideal for mounting remotely on moving stages. The compact EtherCAT drive module supports up to four digital incremental encoder channels and up to two absolute encoder channels. It includes a Serial Peripheral Interface (SPI) to support other feedback devices, such as autofocus signals.

"The UDMSD Series is designed for cost-sensitive applications that demand high-performance motion control in a small package," said Jason Goerges, ACS Inc. General Manager. "These compact EtherCAT drive modules offer superior multi-axis motion control compared to other available options in the market today."

The UDMSD Series operates under any ACS EtherCAT Master Motion Controller. Such a controller can manage networks with up to 64 axes and thousands of IO points. It is available with currents of 1.25/2.5A and 2.5/5A (cont./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.

All connectors of the motors, the encoders and the I/Os are sub-D type connectors. The UDMSD Series is panel or din rail mountable.
