Application Scenarios
An OEM building a high-speed packaging machine needs to coordinate four servo axes (conveyor, cutter, filler, and sealer) with precise electronic gearing and registration. They are using a CompactLogix L45 controller and want to avoid the cost and complexity of a standalone motion controller. The 1768-M04SE is installed in the chassis, creating a fiber-optic SERCOS ring connecting Kinetix 6000 drives. This scenario leverages the module’s ability to handle tight loop cycles (as low as 1 ms) and provide deterministic, jitter-free motion commands directly from the PLC, simplifying the control architecture.
