Servo drive and controller in one

A powerful MCi second processor onboard the Digitax M754 servo drive brings a whole host of machine design opportunities.

The onboard MCi processor executes comprehensive programs that can control multiple drives and motors simultaneously across real-time networks.

Onboard Ethernet using RTMoE (Real Time Motion over Ethernet) provides synchronisation and communication between drives using the Precision Time Protocol (PTP) as defined by IEEE1588 V2.

Simple integration with external components such as Remote I/O, HMIs and PLCs can be achieved with Modbus TCP/IP on the integrated 2-port standard Ethernet switch.

One servo system for ALL your automation needs


Integrated machine controller
Run on-board application programs up to four times faster than a standard PLC.
Control multiple drives across the network for perfectly synchronised multi-axis machine performance.   

Machine Control Studio
Machine Control Studio (MCS) is a flexible and intuitive environment for programming automation and motion control. Fully IEC 61131-3 compliant, it supports Function Block Diagram (FBD), Structured Function Chart (SFC), LadderDiagram (LD), Instruction List (IL), Continuous Function Chart (CFC) and Structured Text (ST) with intuitive IntelliSense functionality.   

Modbus TCP/IP master
Simple integration with external components such as Remote I/O, HMIs and PLCs can be achieved with Modbus TCP/IP on the integrated 2-port standard Ethernet switch.
