[QUOTE="dreambox1959, post: 1160139, member: 314801"] The EGIS motor has a contact which detects the “0” or origin position on the AZ motor and on the EL motor. My program uses these positions to initialize the AZ and EL counters. If we wish to have 9000 due south and 14000 at maximum elevation due south, a value must be added to the AZ and EL counters to correspond to this goal. In the example below (my personal installation) these values are 578 for AZ and 6131 for EL, the two counters take these values when we execute the origin search procedure. These values are to be determined by local testing but will no longer change for a specific site. When these values (1 and 2) are defined, they will allow all positions to be resynchronized in the event of a breakdown or mechanical intervention. The true minimum limits must be greater than these numbers (3 and 4). [SIZE=3][ATTACH type="full" width="604px"]155248[/ATTACH][/SIZE] [/QUOTE]
