(2) Move Distance + Limit Value Setting (#1550, #1750, #1950) 100 _ Set Value __ 99999999
Parameters #1550, #1750 and #1950 are for setting the software LS in the + direction
from the origin on the X-, Y- and Z-axes, respectively.
The setting unit "1" represents 0.001 mm. For example, "10000" means 10.000
mm, and When motion beyond this distance from the reference point is attempted, an
alarm occurs.
(3) Move Distance -- Limit Value (#1551, #1751, #1951) -99999999 __ Set Value __ -100
Parameters #1551, #1751 and #1951 are for designating the software LS position as
measured from the reference point along the X-, Y- and Z-axes, in the - direction. The
setting unit "1" represents 0.001 mm. For example, "-20000" means a movable rang e
from the reference point to -20.000 ram, and any attempt to move beyond the LS will
cause an alarm.

5.5.7 BACKLASH COMPENSATION VALUE SETTING (#1405, #1605, #1805)
0 __% SET VALUE __ 127
Parameters #1405, #1605 and #1805 are for setting the backlash compensation values for the
ball screws, etc. of the X-, Y-, and Z-axes, respectively. The set backlash compensation
values are automatically added to the movement command values. The setting unit "1"
represents 1 pulse. Where the compensation amount is _ (tim),
B
Backlash compensation value = _ x A
5.5.8 PITCH ERROR COMPENSATION
(#1552, #1752, #1952, #1553, #1753, #1953, #1410 TO #1473, #1610 TO #1673, #1810 TO #1873)
For each axis, the ball screw pitch error for successive intervals, starting from the reference
zero point, may be stored as a parameter value for use for automatic compensation. This
function becomes effective after a return-to-reference point.
The compensation interval length, the compensation start point, and the compensa-
tion amount are set for X-, Y- and Z-axes as parameter values. Where the compensation
amount is _ (tt m),
Pitch error compensation B
set value = _ x "A
