*1 Check is not made when the current feed value is not updated ( Page 132, Section 5.2.3 (11)) at the setting of
"current feed value" in "[Pr.14] Software stroke limit selection" during speed control.
*2 Valid only when "1:valid" is set in the "[Pr.15] Software stroke limit valid/invalid setting".
*3 The value in "[Md.20] Current feed value" will differ according to the "[Pr.21] Current feed value during speed control"
setting.
*4 When the unit is "degree", check is not made during speed control.
*5 When the unit is "degree", check is not carried out.

Checks 1) and 2) in Page 536, Section 12.4.3

(2) are carried out.
For speed control: The axis decelerates to a

stop when it exceeds the software stroke limit

range.

For position control: The axis comes to an
immediate stop when it exceeds the software
*3*4

stroke limit range.

new current value is outside the software
stroke limit range.

Check not carried out.
*5 Check 1) in Page 536, Section 12.4.3 (2) is

carried out.
The machine will carry out a deceleration stop
when the software stroke limit range is


exceeded. If the address falls out of the
software stroke limit range, the operation can
be started only toward the movable range.
