Operation
12. “SYSTEM” mode
7. Arch position [pulse] /ARCH
When an arch motion command (optional PTP operation) is executed, arch movement
begins when the robot enters the arch position range set by this parameter for the
target position. This parameter is set to a value unique to each axis when initialized.
When the axis specified for arch movement starts PTP movement toward the specified
position and enters the arch position range, the other axes start to move. When those
axes enter the arch position range, the arch-specified axis moves by PTP toward the
target position. Movement time can be shortened by making this value larger since
there is a greater overlap for axis operation.
The value set for the selected axis is displayed in converted units on the 3rd line of the
MPB screen.

, and . keys and then press the
key. If the value you input was a real number (number containing a decimal point),
then it is converted into pulse units.
5) Repeat the above steps 3) and 4) if necessary.
6) Press the
ESC
key to quit the edit mode.

CAUTION
• The arch-specified axis may
sometimes reach the target
position faster than the other
axes if the arch position is large.
So set an accurate value for the
arch position.
• Movement may be along different
paths during arch operation due
to the movement speed. Check the
arch motion at a speed at which
the robot actually moves.
