The coordinate values of stored stroke check 1 in the positive and
negative directions are set for each axis in the machine coordinate
system. The outside area of the two checks set in the parameters is
inhibited.
Set the machine coordinates of the
(Xp,Yp,Zp) boundaries in the positive direction (Xp,
Yp, and Zp) using parameter No. 1320,
and those of the boundaries in the
negative direction (Xm, Ym, and Zm)
using parameter No. 1321. The
(Xm,Ym,Zm)
prohibited area thus becomes the
hatched area in the figure on the left.
NOTE
1 For axes with diameter specification, a diameter
value must be set.
2 When the parameters are set as follows, the stroke
becomes infinite:
parameter 1320 < parameter 1321
For movement along the axis for which infinite
stroke is set, only increment commands are
available. (The stored stroke limit switching signal
also becomes invalid.) If an absolute command is
issued for this axis, the absolute register may
overflow, and normal movement will not result.
3 The prohibited area specified with these
parameters is invalid if bit 2 (LMS) of parameter
No. 1300 is set to 1 and stored stroke limit
switching signal EXLM <G007#6> is set to 1. In
such a case, the settings of parameters No. 1326
and 1327 are used, instead.

When the machine requires little change in cutting feedrate during
cutting, a cutting feedrate can be specified in the parameter. This
eliminates the need to specify a cutting feedrate (F command) in the
NC program.
The cutting feedrate set by this parameter is valid after the CNC is
placed in the clear state by power-up or a reset until a feedrate is
specified by a program command (F command). After a feedrate is

NOTE
1 This parameter is valid only during linear
interpolation and circular interpolation. Even when
this parameter is set, clamping to a maximum
