Setup variant with large distance between main row and auxiliary row

If, due to space constraints, the modules of an axis system cannot be set up in one row, some of the modules must be installed in a second row. This variant is used if there is a large distance of up to 50 m between the main row and the auxiliary row.

Applications in this setup must be tested by SEW-EURODRIVE for the individual application. Contact SEW-EURODRIVE.

  • Use of DC link chokes in the connection from the main row to the auxiliary row.
  • Adapted controller settings in the CFC control mode.
