MC_SetAcceptBlockedDriveSignal

There are situations in which a drive no longer follows the NC setpoints, e.g. if an axis reaches a limit switch. The NC interprets such a situation as an error, and the drive is stopped. In some cases the user may want to provoke such a situation deliberately, e.g. in order to move to a limit switch for a reference run. The function MC_SetAcceptBlockedDriveSignal can be used to temporarily prevent the NC axis generating an error in situations where the drive no longer follows the NC setpoints.
