B&R 0GH-DM476

Model Series: ACOPOS 6D (ACOPOSmicro 6D)

Product Overview:
The 0GH-DM476 is a single-axis servo drive from B&R’s ACOPOS 6D product line. It is a compact, highly integrated digital servo drive designed for precise motion control of permanent magnet synchronous motors (PMSM) and asynchronous motors. The drive features an integrated servo controller and power stage in a single housing, eliminating the need for a separate controller cabinet.

Applicable Industries:
CNC machines, robotics, pick-and-place systems, conveyor systems, packaging machines, printing machines, semiconductor handling.

Installation Requirements:

  • Mount on DIN rail (TS 35) or direct heatsink mounting
  • Ensure adequate ventilation or forced-air cooling above 40 °C ambient
  • Use shielded motor cables (max length per motor type specification)
  • EtherCAT cable: shielded twisted pair, Cat 5e or better
  • Proper grounding of motor and drive chassis mandatory

Usage Notes:

  • Do not operate without heatsink in enclosures with ambient > +40 °C
  • Motor thermal protection is drive-integrated — match motor rated current to drive
  • STO function must be wired for safety-compliant operation
  • Commission via B&R Automation Studio with ACOPOS 6D configuration tool
