      Information

      Overview Manuals Common Applications Product Precautions
      6RA8075-6DS22-0AA0 provides two-quadrant armature conversion and controlled field supply for an engineered DC-drive system.
      • Provides a rated DC armature power path
      • Controls the connected DC-motor field circuit
      • Coordinates speed and current control in the SINAMICS DCM platform
      • Supports staged diagnostics and drive recommissioning

      The converter uses a B6C armature bridge with a separate controllable field rectifier and requires the documented electronics supply, forced-air flow, motor feedback and commissioning sequence. Applications include controlled DC-motor speed and torque operation where motoring is required in two quadrants.

      Important Notice: Confirm 6RA8075-6DS22-0AA0, B6C two-quadrant bridge, 400 V / 174 A armature input, 485 V DC / 210 A output, motor and field ratings, electronics and fan supplies, feedback device, grounding, firmware, parameter backup, interlocks and controlled rotation and braking tests before commissioning.
