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.

Functional Safety

Functional Safety

All Digitax HD drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution.
The addition of an MiS250 safety option extends the built-in STO with the ability to safely monitor and/or restrict the scope of motion.
Safety functions include: STO, SBC, SOS, SS1, SS2, SLS, SSM, SLA, SDI, SLP & SES
For maximum flexibility in the safety system architecture, the modules support both wired and network safety connections: CIP-Safety on EtherNet/IP and Safety over EtherCAT (FSoE).
