0.001 mm (Positive value = Direction of moving away from
the end)
(Used for SCARA axis 3 (Zc) and linear
movement axes (axes 5 and 6 (6-axis type)))
(Fixed to “0” for axis 1 (A1c), axis 2 (A2c) and axis
4 (Rc).)
* Point to note when an absolute encoder is used
If a value near an integer multiple of the phase-Z
interval distance (including offset travel distance
0) is set for this parameter, servo lock will occur
over phase Z upon when an absolute reset is
performed. As a result, the coordinates may shift
by the phase-Z interval pulses.
Never set a value near an integer multiple of the
phase-Z interval distance.
(Provide a sufficient margin with respect to the
servo amplitude.)
