The UDMLC is a series of small footprint EtherCAT modules with dual/ quad-axis universal drives for servo, stepper, and voice coil motors with a power range of 10W to >200W. The type of motor is selected by the user and can be set differently for each drive without hardware change.It is available in three current levels (cont./peak per axis): 1.25/2.5A, 2.5/5A or 5/10A (dual axis version only), and has inputs for four digital incremental and two absolute encoders.The unit is powered by a 12 to 48Vdc motor bus voltage supply and by a separate 15 to 48Vdc control supply that keeps all logic signals alive during emergency conditions.

The miniature size, low weight, and minimal cable interface makes the SPiiPlusUDMLC ideal for mounting remotely on moving axes.
