[Pr.13] Software stroke limit lower limit value
Set the lower limit for the machine's movement range during positioning control.
Emergency stop
limit switch
Home position
• Generally, the home position 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 the speed
control in speed-position and position-speed switching control) or during manual control.
[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. To invalidate the software stroke limit, set the setting value to "current feed
value".
When "2: degree" is set in "[Pr.1] Unit setting", set the setting value of software stroke limit to "current feed value". The error
"Software stroke limit selection" (error code: 1AA5H) will occur if "machine feed value" is set.
[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.
[Pr.16] Command in-position width
Set the remaining distance that turns the command in-position ON. The command in-position signal is used as a front-loading
signal of the positioning complete signal. When positioning control is started, the "Command in-position flag ([Md.31] Status:
b2)" turns OFF, and the "command in-position flag" turns ON at the set position of the command in-position signal.
