8 Setting the Tool Entry Prohibited Range
8.2.2.6 Stored Stroke Limit for Rotation Axis
Stored stroke limits I and II are used as the stored stroke limit for the rotation axis. The area between the maximum and
minimum values of the prohibited range's parameters, which does not contain the 0 point of the basic machine
coordinate system, is the entry prohibited range.
The prohibited range parameters for the rotation axis can be set to establish "maximum value < minimum value"("#2014
OT+" < "#2013 OT-", "#8205 OT-CHECK-P" < "#8204 OT-CHECK-N"). This will be handled in the same manner as if
"maximum value > minimum value"("#2014 OT+" > "#2013 OT-", "#8205 OT-CHECK-P" > "#8204 OT-CHECK-N").
(Example)Stored stroke limit I (maximum value and minimum value of prohibited range parameter)
#2013 OT -: -70.000°
#2014 OT +: 60.000°
Stored stroke limit II (maximum value and minimum value of prohibited range parameter)
#8204 OT-CHECK-N: 30.000°
#8205 OT-CHECK-P: 80.000°
8.2.2.7 Precautions
(1) If the maximum value and minimum value of the stored stroke limit's prohibited range are set to the same value, the
following will occur.
(a) When the maximum value and minimum value are set to "0", if the outside is the prohibited range, the entire
range will be prohibited. If the inside is the prohibited range, the entire range will be the moveable range.
(b) If data other than 0 is set for the maximum value and minimum value, the entire range will be the moveable
range.
(2) The stored stroke limit IC is valid when the axis parameter #2063 is changed. If changed during automatic
operation, the function will be validated after the smoothing for all axes reaches 0.
(3) Make sure that the lower limit value of the stored stroke limit IC setting value is "smaller than the upper limit value".
(4) To set the inside of the specified range as a prohibited range, set the parameters as follow:
EX. There are 2 methods to set 10° to 70° as a prohibited range.
(Method 1) #2013 OT-: 70° #2014 OT+: 370°
(Method 2) #2013 OT-: 370°#2014 OT+: 70°
104
(A): Moveable range
(B): Prohibited range by stored stroke limit I
(C): Prohibited range by stored stroke limit II
