X2 RESOLVER SETUP
Path HOME - FUNCTION - MENU KEY 6 (x4) - ENTER
or From Models or System Setup :-
CONFIG - MENU KEY 6 (x4) - ENTER
Note This function is only available if the “Resolver Type” in
System Setup - Fitted Options has been set to “EG-01 Fitted”.
If the “Extended Az” in System Setup - Fitted Options has
been set to “Fitted” this line of the Configuration menu reads
“Extended Azimuth Setup”. (see previous page)
Description The EG-01 resolvers have a 1:2 gear ratio between the input
shaft and the angle data output. This is in order to achieve
higher resolution. However it means that the output moves
through 720 for 360 of input rotation. Thus in Azimuth the
INTRAC seeks to initially resolve this 180 ambiguity.
