: Check valid
: Check only carried out at start. (If "current feed value" is set in the " Pr.15 Software stroke limit selection", the
check will not be carried out when the Pr.22 Current feed value is updated.)
– : Check not carried out (check invalid).
: Valid only when "valid" is set in the " Pr.16 Software stroke limit valid/invalid setting".
3
* : The value in "Current feed value (RWrn+0 to 1, RWrn+8 to 9)" will differ according to the " Pr.22 Current feed value
during speed control" setting.
4
* : When the unit is "degree", the check is not performed during speed control.
5
* : When the unit is "degree", the check is not performed.
(2) Software stroke limit check details
An error shall occur if the current value*
stroke limit range*
1)
(Check "Current feed value (RWrn+0 to 1, RWrn+8 to 9)" or
" Md.30 Machine feed value".)
An error shall occur if the command address is outside the
software stroke limit range.
2)
(Check " Da.5 Positioning address/movement amount".)
1
* Check whether the "Current feed value (RWrn+0 to 1, RWrn+8 to 9)" or " Md.30 Machine
feed value" is set in " Pr.15 Software stroke limit selection".
2
* Moveable range from the " Pr.13 Software stroke limit upper limit value" to the " Pr.14
Software stroke limit lower limit value".

3, 4
*
When the current value is changed, an error will not
occur even if the new address is outside the software
– stroke limit range. However, an error "start outside
stroke limit +/–" (error code: 507/508) will occur at the
next operation start.
– Check not carried out.
5 Check 1) in the previous section (2) is carried out.
*
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 operation
5
*
can only be started toward the moveable range after the
error is reset.

Processing when
an error occurs
An "axis error" will
occur, and the
operation will not start.
Processing at check
immediately as soon as the
software stroke limit range is
exceeded.
