Description
The HOME command performs multiple absolute position pattern acquisitions in
order to reliably establish the initial position of each axis. The absolute reference sys-
tem for each axis of the robot is established by moving as much as 10mm (1/2”) the
robot forward/backward repeatedly (pinging), centered about the initial starting
position unit the HOME command is either successfully completed or an error is gen-
erated. The sequence to determine its location is described below.
Sequence for multi-axis Homes:
R axis (homes toward retract position)
Z axis (homes downward, only on robot’s with the Z-Axis option)
T axis (homes counterclockwise)
If a HOME command is entered and the robot is already at the HOME position, no
motion will occur.
