If you program an L--word in a G13, or G13.1 block, an error occurs

This section describes 3 programming situations in which QuickPath Plus

can be used:

Only one end coordinate known

No end coordinate known (L)

No intersection known

One End Coordinate Known

Many times part drawi ngs give a programmer only one axis endpoint for a

path and require that the other axis endpoint be calculated by using a given

angle. The following QuickPath Plus feature eliminates the need for this

calculation. This must be a linear block. See page 12-17 for circular

QuickPath Plus.

The format for this block is as follows:

A__ X__ ;

Z__

Where: Is :

A Angle this word,determined in AMP by your system installer,defines the angle

ofa linear path. Thismanualassumesthatthe A--wordis used. T he

angle isapositivevaluewhen measuredcounterclockwise fromthe first

axisdefining thecurrentlyactiveplane and a negative valuewhen

measuredclockwise. The angle is in unitsof degrees.

X,Z End Point thisword is usedtoprogramoneofthe coordinatesofthe end pointofa

linearpath. The controlcalculatesthe otherend point automatically. This

canbeanyaxis word thatis in thecurrentplane.

You can only program one axis word from the active plane in this block.

Any axis word that is not in the current plane is executed as a normal linear

move to that coordinate and combined with the QuickPath Plus generated

path. If both axis words from the current plane are entered in the block,

the angle is ignored and the control moves to the coordinate position

programmed with the axis words. All examples in this section assume the

ZX plane is active.

Important: If the value of the angle (A--word) is 0

° or 180°, the second

axis in the active plane must be programmed in the block as the endpoint.

If the value of the angle is 90

° or 270°, the first axis in the active plane

must be programmed in the block as the endpoint.
