Network servo drive for centralized and decentralized motion applications

Digitax HD M750 Ethernet is a network servo drive for centralized and decentralized motion applications, featuring multi-protocol Ethernet ports enabling support of real-time Ethernet with RTMoE (Real-Time Motion over Ethernet). Additional protocol support includes Modbus TCP and EtherNet/IP or PROFINET RT used with PLC Controlled Motion for centralized controllers.

The new Digitax HD M750 Ethernet servo drive also hosts the on-board Advanced Motion Controller for distributed 1.5 axis motion control.

Open, efficient, synchronized Ethernet

Maximize 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.

RTMoE

Digitax HD’s standard Ethernet also 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.

Minimum size, maximum performance!

Due to our innovative design you only increase drive size when option modules are used, achieving significant space saving in the overall configuration.

See the "Options" tab for details about the flexibility of Digitax HD M750 Ethernet.

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 EnDat 2.2, Hiperface SinCos, Incremental Quadrature, SinCos, BiSS-C, SSI, Resolvers and others.
• 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 data
• High speed network synchronization of less than 1 μs jitter (typically (typically <200 ns) and 1 ms cycle time for synchronous cyclic data
• Multi-protocol Ethernet support of EtherNet/IP or PROFINET RT in addition to Modbus TCP/IP, HTTP and SMTP

Advanced 1.5 axes Motion Controller, key features include:

• 250 μs cycle time
• Motion profile generator
• Electronic gearbox
• Interpolated cam
• Homing functions
• High speed position freeze

Minimum size

• With its 1.6 in (40 mm) width and with the option bracket of only 0.86 in (22 mm), the new intelligent servo drive provides a competitive maximum width of 2.44 in (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 8 in (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 to add features and functionality for Communication, Feedback, I/O and/or Machine Controller (please see the "Options & Accessories" section for details)
• Multi-protocol Ethernet

Safety on-board

• Reduced downtime with machine safety
  - Integrated dual safe torque off
  - Meets SIL3 (Safety Integrity Level 3) and PLe (Performance Level e)

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).
