: Check valid
: Check is not made when the current feed value is not updated (Refer to [Pr.21]) at the setting of "current feed value"
in "[Pr.14] Software stroke limit selection" during speed control.
– : Check not carried out (check invalid).
: Valid only when "0: valid" is set in the "[Pr.15] Software stroke limit valid/invalid setting".
1 : The value in "[Md.20] Current feed value" will differ according to the "[Pr.21] Current feed value during speed control"
setting.
2: When the unit is "degree", check is not made during speed control.
3: When the unit is "degree", check is not carried out.

For speed control : The axis decelerates to a stop
For position control: The axis comes to an immediate

The current value will not be changed if the new
current value is outside the software stroke limit range.
– Check not carried out.
Check 1) in the previous section [2] is carried out.
*3
The machine will carry out a deceleration stop when
the software stroke limit range is exceeded. If the
address is outside the software stroke limit range, the
*3
operation can only be started toward the moveable
range.
Check 1) in the previous section [2] is carried out.
The mode switches to the position control mode when
the software stroke limit range is exceeded, and the
operation immediately stops.
