I have an ASA rotator fitted to my ASA classical Cassegrain. If I operate this using ACC it rotates in the shortest direction to get to the desired angle - which is what I would expect.

However if I do a series of rotations, all under 180 deg (eg 179, 358, 177, 356) it keeps going the same way and wraps the cable around the rotator. Potentially very dangerous as I intend to operate remotely.

Is there a way of configuring the rotator so that it never goes more than a specified number of degrees in the same direction before reversing direction? This would need to work both with ACC and any higher level control via ASCOM (eg from The Sky, Maxim or ACP).

Sorry if this is has an obvious solution - first time I've used a rotator.
