The multi-protocol drive that does it all

Digitax M750 is an extremely versatile multi-protocol network drive. It supports EtherNet/IP, Profinet RT and Modubus TCP/IP as well as peer-to-peer synchronisation with RTMoE (Real Time Motion over Ethernet). It also features and onboard Advanced Motion Controller for distributed 1.5 axis motion control.

One servo system for ALL your automation needs

The perfect mix of application-specific features developed into a single solution  

Open, efficient, synchronised Ethernet
Maximise machine productivity through high performance deterministic Ethernet. Access future developments in IT-based industries where billions of nodes are installed, future proofing your investments. Ethernet webpages hosted onboard the M750 Ethernet drive 

Rationalise inventory
Machine builders often need to maintain multiple PLC environments to serve different geographical markets. With its multi-protocol ethernet interface and on-board motion capability, Digitax M750 allows the same drive and motion design to be used in different ecosystems, rationalising inventory and spares             

Reduce design time
Share the same design on multiple systems to reduce complexity. 
PLC Controlled Motion simplifies integration of the M750 multi-protocol drive into the most common PLC environments. It provides easy access to the drive's onboard Advanced Motion Controller through a simplified drive configuration workflow, automatic configuration of the communication links and PLC function block libraries.
