Intelligent control module accommodates multiple electric drives for coordinated movement

The CPX-CMXX is ideal for parts handling and positioning applications such as pick-and-place, palletising, machine loading and unloading, inspection/measuring, and labelling. The module can operate autonomously or in response to signals from a host controller – it features a built-in PLC-compatible interface. It can store and execute simple individual axis movements, and can also coordinate the movement of two groups of axes, each containing up to four axes. There are 1,024 position sets available for each of the two groups of axes; these can either be linked and executed in sequence, or multiple sets can be executed in synchronism, which provides considerable control flexibility. The module communicates with the various drive modules via CANopen, using the standard fieldbus FHPP handling and positioning profile.

All configuration, parameterisation and commissioning of the CPX-CMXX module is carried out using Festo’s highly intuitive Windows-based FCT software. The motion control sequences can be programmed, but they can also be set up using parameterisation or teach-in, without the need for connection to a host controller. The module is equipped with a standard Ethernet 10/100 baseT interface for parameterisation, as well as a service interface for a Festo CPX-MMI handheld terminal, and features front panel LEDs to indicate program status and provide local diagnostic feedback. A preliminary test of the entire system can also be performed without a host controller.

Festo’s CPX multifunctional terminals provide machine builders with a very flexible, modular approach to control, condition monitoring and diagnostics. The terminals can form part of centralised, decentralised and hybrid control schemes, and are compatible with all major fieldbus systems, as well as industrial Ethernet. Individual modules can be changed at will, enabling systems to be reconfigured or expanded without altering the wiring.

Festo produces a wide range of CPX-compatible modules, including intelligent analogue I/O modules for temperature sensing and signal detection, PNP and NPN digital input units, M12 and M8 connection blocks, and two types of position transducers for use with pneumatic actuators.
