13) XVEL
Input type XVEL <number> or XVEL <L variable>
Terminology <Number>: Set the number of variable for a velocity from the F Table.(0 ~ 9)
<L variable>: Set the variable for a velocity from the L-VAR Table.(L0 ~ L1999)

command
PTP,IPTP
Parameter Maximum velocity(P18), acceleration or deceleration time(P23), deceleration time (P65)
Explanation A command(PTP, IPTP) related to the X-axis movement is executed at a velocity of the
set variable.
The once set velocity is effective until a reset.
If the VEL is commanded and the XVEL is commanded next, then the VEL becomes effective
during interpolation movement and the XVEL becomes effective during rapid movement.
That is, the interpolation velocity and the rapid velocity can be designated
separately.
If the XVEL is commanded and the VEL is commanded next, then the XVEL command is
cancelled and the VEL velocity becomes effective.
The XVEL is only possible during rapid movement(PTP,IPTP).
Example of
use
XVEL 0
XVEL L0
Designate a velocity by using a variable F0.
Designate a velocity by using a variable L0.
