Commissioning

During commissioning, power units connected in parallel are treated like a power unit on the

line or motor side.

For detailed information about commissioning, supplementary operating conditions and

parameterization options, please refer to references /IH1/: SINAMICS S120 Commissioning

and /LH1/: SINAMICS S120/S150 List Manual starting at parameter r7002ff.
