There are t w o w ays to set the offsets:
1. Enter the current pos i t i on of the antenna i nto the Cu rr e nt pos i t i on [ d e g ] f i e l d. A t

to w er) w i th a kno w n l ook ang l e. W hen the current pos i t i on i s entered, the
offsets are automat i ca ll y computed.
2. Enter the offsets d i rect l y by se l ect i ng Offs e ts [ d e g ] and enter i ng the des i red

5.8.6.4 Mot i on L i m i ts M e nu
There are t w o types of mot i on li m i ts:
Soft w are trave l li m i ts ( " soft li m i ts " ): The A C U w ill not dr i ve the antenna
beyond the soft li m i ts i f the opt i on i s enab l ed. The li m i ts funct i on as a
" pre li m i t " , stopp i ng mot i on of the antenna before i t reaches the e l ectr i ca l trave l
li m i t s w i tches. The soft li m i ts shou l d be set such that w hen the antenna i s
mov i ng at i ts fastest rate and h i ts the soft li m i t, i t stops j ust short of tr i pp i ng
the li m i t s w i tch.
Mot i on errors: The mot i on errors prevent mot i on of an ax i s i n the event that
antenna mot i on as reported by the pos i t i on encoders does not correspond w i th
pred i cted mot i on due to A C U motor commands.
