Base servo drive for configuration flexibility Digitax HD M751 Base servo drive offers configuration

Network servo drive for centralized and decentralized motion applications

Digitax HD M751 Ethernet is a network servo drive for centralized and decentralized motion applications, featuring the SI-Ethernet option module enabling support of real-time Ethernet, including RTMoE (Real-Time Motion over Ethernet).

The new Digitax M751 Ethernet servo drive also hosts the on-board Advanced Motion Controller for distributed 1.5 axis motion control.

• Features

  Maximum performance

  • 300% peak current performance pulse-duty overload
  • Optimized control loops for high dynamic performance
    • 62.5 μs current loop
    • 250 μs position and speed loop
  • Up to 16 kHz switching frequency (default ratings specified at 8 kHz)
  • Supports a wide range of feedback technologies including Quadrature, SinCos (including absolute), SSI, BiSS, EnDat (up to 4 Mb with EnDat 2.2) and resolvers
  • Maximum performance package with high torque density, low inertia Unimotor hd servo motors
  • Supports RTMoE (Real-Time Motion over Ethernet) which provides synchronized communication between drives using the Precision Time Protocol as defined by IEEE1588 V2:
    • Distributed clocks are used to automatically synchronize the position, speed and current loops across all drives
    • 1 ms cycle time for synchronous cyclic dat
    • High speed network synchronization of less than 1 μs jitter (typically (typically <200 ns) and 1 ms cycle time for synchronous cyclic data
  • Advanced 1.5 axes Motion Controller, key features include:
    • Real-time tasks
    • 250 μs cycle time
    • Motion profile generator
    • Electronic gearbox
    • Interpolated CAM
    • Homing functions
    • High speed position freeze

  
  

  Minimum size

  • 40 mm drive width and option bracket adds 22 mm, providing a highly competitive maximum drive width of 62 mm
  • Reduce cabinet height by directly stacking rows of drives. Patented Ultraflow™ technology expels heat directly outside of the cabinet through the rear of the drive (drive heat dissipation can also be achieved via vents on the top of the drive, as standard).
  • Fits into cabinets just 200 mm deep

  
  

  Easy installation and setup

  • DIN rail alignment
  • Kits for easy multi-axis installation
  • Single motor cable and electronic motor name plate for fast set up
  • Seamless motor-drive pairing with Unimotor hd servo motors
  • Easy access pluggable connectors
  • Rapid commissioning with the Unidrive M Connect PC tool and SD cards
  • Machine Control Studio provides a flexible and intuitive environment for programming automation and motion control features
    • Programmable with IEC61131 standard languages

  
  

  Flexibility

  • Two option slots for functionality extension and customisation (see available option modules)
  • Built-in RS485 communications

  
  

  Safety on-board

  • Reduced downtime with machine safety

    - Integrated dual safe torque off

    - Meets SIL3 (Safety Integrity Level 3) and PLe (Performance Level e)

• Options

  Keypads

  	Remote Keypad RTC The keypad is remote mountable, allowing flexible mounting on the outside of a panel (meets IP54/NEMA 12). Three line plain text, multi-language LCD keypad for rapid set-up and helpful diagnostics. Battery operated real-time clock allows accurate time stamping of events, aiding diagnostics.
  	KI Compact Display The display (fitted on M753, optional on M751) ensures access to drive diagnostics even in the absence of network connectivity. Includes 2 rotary switches for hardware setting of the node address for faster commissioning of the motion network.
  	KI-Compact 485 Adaptor This allows the drive to communicate via RS485. This is commonly used for programming if the drive has no keypad.
