Tolomatic integrated servo motor and drive (with PROFINET) automates simple motion axes

The Tolomatic ACSI integrated servo/motor/controller is now available with PROFINET Industrial Ethernet protocol — to let engineers design easy-to-use and cost-effective electric actuator setups for single-axis applications. The integrated package is suitable for replacing pneumatic cylinders and automating any simple axis of motion with Siemens or other PROFINET enabled PLCs.

With built-in configurations for Tolomatic electric actuators, the ACSI integrated controller automatically configures the motor, actuator, safety limits and other key settings inside the controller for quick and seamless integration. The PROFINET protocol is in addition to Tolomatic’s existing EtherNet/IP and Modbus-TCP options for the ACSI.

PROFINET is the standard for industrial networking in automation. It connects devices, systems and cells, facilitating faster, safer, less costly and higher quality manufacturing. It easily integrates existing systems and equipment while bringing the richness of Ethernet down to the factory floor, according to the organization’s website.

“Adding the PROFINET protocol to the existing EtherNet/IP and Modbus-TCP options for the ACSI controller gives OEMs flexibility with multiple PLC vendors while being able to standardize on a single mechanical / actuator design,” said Aaron Dietrich, director of marketing,Tolomatic, Inc.

“Plus, the performance range combined with IP65 rating makes the ACSI a great fit for many applications where the OEM can take advantage of the protocol and control flexibility.”

As an integrated servo motor and drive, the ACSI creates a space-saving design. The integrated package doesn’t need space in a control cabinet, making it suitable for machine retrofits and also for displacing pneumatic cylinder applications. Available in both linear setup and rotary setup, the ACSI is easily configured to the target user units.

Certified by PI North America (PROFINET governing organization) to PROFINET v2.33 standards, the ACSI controller can be implemented on RT (realtime) networks as an I/O device. Available GSDML file and an archive of data blocks and function blocks for use with the latest Siemens PLC’s eases setup and allows for ultra-fast deployment into PROFINET control systems.

Available in two sizes (NEMA 23 and 34), with peak torques up to 1.35 N-m (12 in-lb), the ACSI features standard M12 connectors, an IP65 rating, dual Ethernet ports with LED indicators for easy troubleshooting and a USB microprogramming port. All models of ACSI come equipped with 24 Vdc digital I/O (4 in / 2 out) and 0-10 Vdc / 4-20 ma analog I/O (1 in / 1 out) for distributed sensors and logic to expand the network. The dual Ethernet ports with integrated managed switch allow many axes of ACSI to be daisy-chained without affecting network performance.

Tolomatic will mount the ACSI to the actuator of choice, configure it, test it and ship it to the customer under one part number, saving time with purchasing multiple part numbers and also creating one point of responsibility for application support.
