[QUOTE="pbasista, post: 1140053, member: 418178"] Hi, thank you everyone for all the suggestions. The motor now works correctly. TL;DR: All that was necessary to do was to reset it. As I have mentioned earlier, there is no dedicated reset button on this motor device. I have examined it in detail while it was disassembled and apart from the two buttons for navigating east and west, it contains no other externally accessible microswitches. BTW, it has three more [I]internal[/I] microswitches to control the positioning limits of the main gear. One is indicating the westmost angle, the second is indicating zero angle and the third is indicating the eastmost angle. The motor itself or some of its transmission gears probably uses some hall sensors for precise monitoring of its movement. As [USER=215446]@deeptho[/USER] has suggested and as the manual linked to by [USER=175144]@Channel Hopper[/USER] mentions, this motor device indeed [I]does[/I] have the capability to perform a hardware reset by pressing both navigation buttons simultaneously. I have done that and afterwards the motor started to work correctly again. It can now navigate to any position between roughly 80 degrees west and 80 degrees east, using either USALS, GoTo function or manual movement by pressing the buttons on the motor device. The linked manual also mentions that this motor device is supposed to have some kind of "Programmable Software Limit" feature. It seems like incorrect value of this limit might have been the root cause of this issue. I am unsure how those limits are supposed to be configured. I do not recall doing it explicitly. Perhaps the software which I typically use to control the motor device (i.e. Tvheadend) does this implicitly in some circumstances. I do not know. In any case, thank you for all help. [/QUOTE]
