Millimeter machine 1 mm/min 10 – 60000 1 – 6000
Inch machine 0.1 inch/min 10 – 60000 1 – 6000
Rotation axis 1 deg/min 10 – 60000 1 – 6000
If zero is specified for all axes, the machine does not decelerate at corners.
When the function for determining the velocity considering the velocity
difference at corners is used, the system calculates the feedrate whereby a
change in the velocity element of each axis does not exceed this parameter
value at the interface between blocks. Then the machine decelerates using
acceleration/ deceleration before interpolation.

USE Automatic velocity control is:
0 : Not applied.
1 : Applied.
ZAG The velocity is:
0: Not determined according to the angle at which the machine descends
along the Z–axis.
1: Determined according to the angle at which the machine descends
along the Z–axis.
NOF In a block where automatic velocity control is validated, the F command
is:
0 : Validated.
1 : Ignored.
(Maximum speed of automatic feedrate control set by parameter No. 8465
is used for command speed in spite of F command)
