X2 SETUP

X2 resolvers have a 1:2

gearbox on the input shaft

to provide extra resolution.

This screen allows the user

to resolve a +/- 180º

ambiguity in the displayed

main axes angles.

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.
