Errors that are still present but the causes of which have been rectified can be ac-
knowledged by means of a 0 –> 1 edge at the "Acknowledge error" (p2103.5) signal.

Note
Under the condition that the drive system was commissioned with STARTER and
no PROFIBUS telegram was activated, the infeed can be powered-up by issuing
an enable signal at the EP terminals and a positive signal edge at OFF1 (p0840).
