Updates to the Motion LIbrary A-3
Modified library Functions
LatchGetOutput(channel);
In previous Ultraware versions, this library function returned the
motor encoder output position captured when the latch occurred. The
axis feedback offset was not applied to the latched positions.
In Ultraware 1.20 Motion Library, this function returns the Axis
feedback position, with the feedback offset added, captured when the
latch occurred.
This applies to the motor latches, 1 & 2 only, but does not apply to
the auxiliary latches, 3 & 4.
