(a) Setting range
*1 1 to 32767: Set as a decimal
32768 to 65535: Convert into hexadecimal and set
(2) [Pr.12] Software stroke limit upper limit value
Set the upper limit for the machine's movement range during positioning control.
(3) [Pr.13] Software stroke limit lower limit value
Set the lower limit for the machine's movement range during positioning control.
• Generally, the OP is set at the lower limit or upper limit of the stroke limit.
• By setting the upper limit value or lower limit value of the software stroke limit, overrun can be prevented in
the software. However, an emergency stop limit switch must be installed nearby outside the range.
• To invalidate the software stroke limit, set the setting value to "upper limit value = lower limit value". (If it is
within the setting range, the setting value can be anything.)
• When the unit is "degree", the software stroke limit check is invalid during speed control (including speed-
position switching control, position-speed switching control) or during manual control.
(a) Setting range
(4) [Pr.14] Software stroke limit selection
Set whether to apply the software stroke limit on the "current feed value" or the "machine feed value". The
software stroke limit will be validated according to the set value.
(5) [Pr.15] Software stroke limit valid/invalid setting
Set whether to validate the software stroke limit during JOG/Inching operation and manual pulse generator
operation.
