4 PARAMETERS FOR POSITIONING CONTROL
POINTS

10 inch]. If those values are less than -2147483648[pulse/0.1μm/10
is controlled with 2147483647[pulse/0.1μm/10
(2) If the absolute position command (ABS instruction) is set when the stroke limit
is invalid, it is controlled as shortcut operation.
(3) The circular interpolation and helical interpolation (other than linear axis)
including axis that the stroke limit is set to invalid cannot be executed.
A minor error (error code: 107 to 109) will occur, and operation does not start.
(4) If the stroke limit is set to invalid for axis of unit (pulse, mm, inch) in the real
mode or real mode axis, the ABS-
(pulse, mm, inch) when the absolute method is set as end point address in the
speed-switching control (VSTART).
A minor error (error code: 119) will occur, and operation does not start.
(5) The high-speed oscillation function cannot be used in the axis that set the
stroke limit invalid.
(6) When executing a speed change to negative speed for the axis with stroke
limit set to invalid, the operations below occur based on the control mode
being executed.
