Festo EHMH is a muscular cantilever axis with rack and pinion technology that handles payloads up to 200 kilograms. As a Z-axis, EHMH includes the EGC-HD heavy-duty toothed belt or ball screw model as the X-axis, CPX-E control system, CMMT-AS AC servo drive, EMMT-AS servo motors, plus other accessories.
EHMH comes in two sizes. It combines a solid steel profile and recirculating bearing guide, with feed force that speeds up to 1.5 metres per second. EHMH can be configured for enhanced safety protection up to performance level d. The interpolation performed by multiple EHMH-based gantries can be controlled from a single CPX-E motion controller. The CPX-E is an alternative to the larger controllers required to manage multiple articulated robots.
