M753

Extends the Unidrive M range with maximum servo performance in a minimum size package. Optimized for high-dynamic applications.

EtherCAT is integrated in the drive. It offers EoE (Ethernet over EtherCAT) support for connecting a PC for comissioning and monitoring via the EtherCAT network.

Leader in compactness and installation for single and multi-axis configurations

  • 3 different sizes up to 48 A peak current, 40 mm width for all sizes
  • Cabinet depth from 200 mm
  • 25 drives up to 16 A can be placed in a 1 m wide cabinet
  • Single cable concept including power conductors and feedback communication
  • From stand-alone drive to modular system with interconnected DC busses

Maximum performance

  • 300% peak current performance
  • Very high torque to size ratio when using Unimotor HD servo motors
  • 62.5 μs current loop
  • 250 μs position and speed loop
  • Unique ‘dead beat’ current controller for maximum bandwidth
  • Notch filter for suppression of mechanical resonances

Flexibly expandable functions via optional modules

  • Digitax HD supports a range of communications, I/O, feedback and machine control option modules.
  • Overall width including modules: 62 mm

Patented Ultraflow technology

  • Control Techniques’ patented Ultraflow™ technology expels heat directly outside of the cabinet through the rear of the drive
  • An intelligently controlled fan minimizes acoustic noise and optimizes fan lifetime
  • Controlling the air flow through the drive protects the drive electronics
  • Ultraflow™ requires only a 32 mm hole in the cabinet meaning rapid, trouble-free installation
