deceleration dogs
*2 For manual rapid traverse before a reference position is set, a jog feedrate
(parameter No.1423) or manual raped traverse rate (parameter No.1424)
is used according to the setting of bit 0 (RPD) of parameter No.1401.
*3 The raped traverse rate set in parameter No.1424 or No.1420 is used
according to the setting of bit 1 (DLF) of parameter No.1404 when reference
position return is perfomed without dogs, or when reference position return
operation is performed with bit 7 (SJZ) of parameter No.0002 set to 1 after a
reference position is set (when reference position return operation is
performed using rapid traverse without deceleration dogs).

Rotaion axis 1 deg/min 6 to 240000 6 to 100000
Specify the maximum cutting feedrate for each axis.
A feedrate for each axis is clamped in cutting feed so that it does not
exceed the maximum feedrate specified for each axis.
NOTE
1 This parameter is effective only in linear and circular
interpolation. In polar coordinate, cylindrical, and involute
interpolation, the maximum feedrate for all axes specified in
parameter No.1422 is effective.
2 If the setting for each axis is 0, the maximum feedrate
specified in parameter No.1422 is applied to all axes and the
feedrate is clamped at the maximum feedrate.
