For the Plastics industry

The MACO Compact is a cost competitive, application specific, programmable logic controller with the advantages of integrated, total machine control in a compact package. It is an expandable system, available with different options to meet OEM and end-user application requirements. Equipped with Ethernet communications, the MACO Compact delivers seamless connection to plant wide systems. A tightly integrated multiple processing architecture, utilizing DSP technology provides <1msec loops. Typical ladder logic execution is less than 0.5msec. High performance ethernet communications is provided for interfacing with the HMI or other devices.

The controller also features built-in diagnostic and process monitoring for multiple shot monitoring, shot to shot repeatability, data storage, “reference/signature” shot and “snapshot” functions. Additionally, online RLD diagnostics allow troubleshooting logic and machine operation with web browsing capability via the internet.

The MACO Compact supports either open or closed loop (IMPACT ™ II) injection process control. Run the machine for a few cycles, and IMPACT II creates a theoretical model of the process. It uses this model along with hundreds of rules to automatically optimize the process to compensate for short and long term deviations in the injection molding process. Injection control features velocity or pressure controlled fill with ramping for up to 10 steps. Transfer mode is user selectable and there are multiple steps of pack and hold, as well as synchronized back pressure and RPM control of up to 10 steps. Eight isolated temperature control loops with the industrybest auto tune algorithm, a full complement of built-in alarm functions, with auto-compensation available for sensor break. There is also an optional 12 zone T/C-Analog card available.
