VP
FUNCTION Vector Position
DESCRIPTION:
The VP command defines the target coordinates of a straight line segment in a 2 axis motion
sequence which have been selected by the VM command. The units are in quadrature counts,
and are a function of the vector scale factor set using the command VS. For three or more
axes linear interpolation, use the LI command. The VP command will apply to the selected
coordinate system, S or T. To select the coordinate system, use the command CAS or CAT.
ARGUMENTS: VP n,m < o > p where
n and m are signed integers in the range -2147483648 to 2147483647 The length of each segment
must be limited to 8
106. The values for n and m will specify a coordinate system from the
beginning of the sequence.
o specifies a vector speed to be taken into effect at the execution of the vector segment. n is an
unsigned even integer between 0 and 22,000,000 for servo motor operation and between 0 and
6,000,000 for stepper motors.
p specifies a vector speed to be achieved at the end of the vector segment. p is an unsigned even
integer between 0 and 8,000,000.

OPERAND USAGE:
_VPn contains the absolute coordinate of the axes at the last intersection along the sequence. For
example, during the first motion segment, this instruction returns the coordinate at the start of
the sequence. The use as an operand is valid in the linear mode, LM, and in the Vector mode,
VM.

Hint:
The first vector in a coordinated motion sequence defines the origin for that sequence. All other
vectors in the sequence are defined by their endpoints with respect to the start of the move sequence.
