Compact Dual/Quad Axis Universal Drive Module for Cost Sensitive Applications
The SPiiPlusUDMlc, or UDMlc, is a compact EtherCAT dual/quad axis drive, designed to meet the needs of OEMs designing control systems for motion demanding equipment that uses small motors, such as pick/place machines, tabletop motion platforms, and wide format inspection/assembly equipment.
The unit’s dual/quad-axis universal drives can run servo, stepper, and voice coil motors with a power range of 10 W to 200 W. The type of motor is selected by the user and can be set differently for each drive axis. The miniature size, low weight, and minimal cable interface makes the unit suitable for mounting remotely on moving axes. 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), supports motor bus voltages from 15-48Vdc, and has inputs for four digital incremental and up to two absolute encoders. A high linearity power stage, full sinusoidal commutation with field oriented control, and advanced position, velocity, and current loop servo algorithms running at an uncompromised 20 kHz sampling and update rate enables nanometer level positioning and ultra-smooth constant velocity control.
