12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
[Pr.12] Software stroke limit upper limit value
Set the upper limit for the machine's movement range during positioning control.
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
*1 When this buffer memory area is set with programs, a calculation is performed in the RD75 to convert a setting value to the value in
each unit. For setting this buffer memory area, take the value after the unit conversion into consideration.
■
Default value
The default value is 2147483647 for all the axes.
[Pr.13] Software stroke limit lower limit value
Set the lower limit for the machine's movement range during positioning control.
• In general, the OP is set at the lower limit or upper limit of the stroke limit.
• Setting the upper and lower limits of the software stroke limit prevents the workpiece to overrun the set range; although, in
addition, place emergency stop limit switches outside and near the range.
• To invalidate the software stroke limit, set the setting value to Upper limit value = Lower limit value. (Set the value within the
setting range, such as the initial value.)
• When the unit is degree, the software stroke limit check is invalid during speed control (including the speed control of
speed-position switching control and position-speed switching control) or during manual control.
■
Buffer memory address
The following table shows the buffer memory address of this area.
■ Setting range
The setting range is the same as that of [Pr.12] Software stroke limit upper limit value.
■
Default value
The default value is -2147483648 for all the axes.
