DESCRIPTION.

Specifies the axes for the planar motion where m and n represent the planar axes and p is the tangent axis.

Return coordinate of last point, where m=X,Y,Z or W.

Specifies arc segment where r is the radius, Θ is the starting angle and ΔΘ is the travel angle. Positive direction is CCW.

Specify vector speed or feedrate of sequence. Specify vector acceleration along the sequence. Specify vector deceleration along the sequence. Specify vector speed ratio

Begin motion sequence, S or T Clear sequence, S or T

Trippoint for After Relative Vector distance.

Holds execution of next command until Motion Sequence is complete. Tangent scale and offset.

Ellipse scale factor.

S curve smoothing constant for coordinated moves

Return number of available spaces for linear and circular segments in DMC-1700/1800 sequence buffer. Zero means buffer is full. 512 means buffer is empty.

Specifies which coordinate system is to be active (S or T)

Operand Summary - Coordinated Motion Sequence

OPERAND

_VPM

_AV

_LM

_CS

_VE

DESCRIPTION

The absolute coordinate of the axes at the last intersection along the sequence. Distance traveled.

Number of available spaces for linear and circular segments in DMC-1700/1800 sequence buffer. Zero means buffer is full. 512 means buffer is empty.

Segment counter - Number of the segment in the sequence, starting at zero. Vector length of coordinated move sequence.

When AV is used as an operand, _AV returns the distance traveled along the sequence.

The operands _VPX and _VPY can be used to return the coordinates of the last point specified along the path.

Example:

Traverse the path shown in Fig. 6.3. Feedrate is 20000 counts/sec. Plane of motion is XY

VM XY

Specify motion plane

VS 20000

Specify vector speed

VA 1000000

Specify vector acceleration

VD 1000000

Specify vector deceleration

VP -4000,0
