14.17 Change the Area of Stored Stroke Limit I

14.17.3 Precautions

(1) For an axis whose parameter "#2190 OT_Rreg" is set to "0", or an axis whose prohibition area includes any R register
outside the user area, the stored stroke limit I area coincides with the settings of the parameters "#2013 OT-" and "#2014
OT+". Changing the area of stored stroke limit I is disabled for these axes.
(2) If the area of stored stroke limit I is changed, the settings of the parameters "#2013 OT-" and "#2014 OT+" are
unchanged.
(3) If you change the area of stored stroke limit I and this causes the present position to be included in the prohibition area, it
is not until axis movement starts that the operation error (M01 0007) occurs. After occurrence of this error (M01 0007), it
is still possible to move the tool manually in a direction opposite to the prohibition area (direction of pulling out the tool).
(4) Even when changing the area of stored stroke limit I is enabled, this change will not affect the operation of the other
stored stroke limit function (IB, IC, II or IIB) or barrier function (chuck or tailstock barrier). The narrower movable range is
applied to operation.
(5) After changing the area of stored stroke limit I, you need to turn OFF and ON the power. Otherwise you are unable to set
the changed area back to the parameters. If needed, enable the same values as the parameter settings to be set in the R
registers.
(6) If you change the values of R registers in which the range of stored stroke limit I has been set, with the "Stored stroke limit
I : Change request" (SLMC) signal (YB60) ON, the area of stored stroke limit I is unchanged. Only at the rising edge of the
"Stored stroke limit I : Change request" (SLMC) signal (YB60), the area of stored stroke limit I is changed.

for checking
(a) Change the setting values of registers. (Area of Soft limit I is not yet changed in this state.)
(b) Change the setting values of registers. (Area of Soft limit I is not yet changed in this state.)
(c) Area of Stored stroke limit I is changed at the rising edge of "Stored stroke limit I : Change request" signal (SLMC).
(7) If you attempt a change of stored stroke limit I area while an identical value (other than zero) is set in OT- and OT+ (R
register settings), stored stroke limit I will be disabled. In this case, the minimum of the R register setting is output to OT-
of the R register for checking, and the maximum of the R register setting is output to OT+.
(8) If the stored stroke limit you have set is exceeding the range of the R registers for checking, the values to be set in these
R registers are clamped at the setting limit.
(9) To the R registers for checking, the setting range of stored stroke limit I is output. The setting values of other function
such as stored stroke limit II are not output to these R registers.
(10) For an axis specified as a diameter designation axis, also use a radius value when setting the R registers.
(11) You are unable to cancel the operation error (M01 0007) by widening the area of stored stroke limit I. Thus cancel the
error first, and then move the axis.
