Relativity four axis CNC drive system for OEM application

This drive system is suitable for use with new, used, retrofitted or OEM CNC machines equipped with unipolar or bipolar stepper motors up to 3.5A per phase. It is available in inch or metric configurations and with worldwide voltage options, tailored to the specific parameters of your machine.

Advanced parameter supervision (APS) continuously monitors position, velocity and acceleration on all axes, preventing over-travel and other mechanical damage due to mis-configured soft limits or other exceptions during normal operation.
