Controlling the drive mechanism comprising a drive body (A), a device (B) driven by (A) and a moment coupling (C) between (A) and (B) which is loosened if the moment exceeds a pre-determined value, comprises: (1) positioning (B) against a mechanical stopper; (2) supplying drive energy to (A), forcing (B) against the stopper; (3) repeating (2) if (C) becomes loose; and (4) controlling (2) in accordance with pre-determined values. The drive mechanism for this process is also claimed, contg. mechanical stopper-forming parts (14,15) for (B) and a monitor device (19) for recording the moment transferred to (B) when (C) is loosened by (A). |
