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 for the maching center system
(FS15–MB) and the lathe system
The data shows the present position with the least input
increment.
2) Once the skip signal has been input to the NC, movement along the
relevant axis is stopped then, after the elapse of the servo delay, the
absolute position can be read.
