1) Read value is determined as follows:
(1) For the machining center system (except for diameter
specification for the FS15–MB) or when the radius is specified
for the axis of the lathe systm.
The data shows double of the present position with the least
input increment as a unit.
(2) When the diameter is specified for the maching center system
(FS15–MB) and the lathe system
The data shows the present position with the least input
increment.
2) The present position of a moving axis can be read whenever the
function instruction is executed.
