Relation between the software stroke limit function and various controls
: Check valid
: Check is not performed when the current feed value is not updated at the setting of Current feed value in [Pr.14] Software
stroke limit selection during the speed control. (
Page 398 [Pr.21] Current feed value during speed control)
-: Check is not performed (check invalid).
: Valid only when 1: Valid is set in [Pr.15] Software stroke limit valid/invalid setting.
*1 The value in [Md.20] Current feed value differs depending on the setting of [Pr.21] Current feed value during speed control.
*2 When the unit is degree, the limit check is not performed during the speed control.
*3 When the unit is degree, the limit check is not performed.

For speed control: The machine decelerates and stops when
the software stroke limit range is exceeded.
For position control: The operation is not performed if the
target address is outside the software stroke limit range.

(1) and (2) in the following section are checked.
Page 236 Details of the software stroke limit check
The machine decelerates and stops when the software
stroke limit range is exceeded. The operation can be started
only toward the direction of the movable range if the target
address is outside the software stroke limit range.
Manual pulse generator operation
