Processing at check
Check is not performed.
(1) and (2) in the following section are checked.
Page 234 Details of the software stroke limit check
■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.
The current value change is not performed if the new current
value is outside the software stroke limit range.
Check is not performed.
(1) and (2) in the following section are checked.
Page 234 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.
