10.5.7 Speed change (CHGV)
The motion dedicated function CHGV command (change velocity) is used to forcibly
change the speed set during positioning control (excluding circular interpolation) and
JOG operation.
(1) CHGV speed change request command
This item describes the number of the axis for which the speed is to be changed
and the new speed.
CHGV (K1, K30000)

POINT
When setting the speed using the CHGV command, set the value given by
multiplying the actual speed by 100 (mm)/1,000 (inch, degree).
