Motion blocks provide access to all of the high-level motion functions in
the motion controllers. See the Installation and Setup manual of your
motion controller for an introduction to the high level motion functions.
Home Axis
The Home Axis performs a homing operation, as selected in the
Procedure menu, and re-defines the actual position of the selected axis.
The Home Axis block resides on the Main Palette.
You cannot home an imaginary axis. Instead, use a Redefine Position
block to change the actual position of an imaginary axis.
A virtual axis can be homed only passively. Note that, in the Configure
Axis Use dialog box, there is no Homing tab. This is because a virtual
axis is configured for passive homing by default. Therefore, it doesn’t
matter whether you select Configured or Passive in the Home Axis block.
In either case, passive homing results.
Stop the electronic gearing motion of a selected Axis. If gearing is
the only motion in progress on the axis, the axis stops immediately
with no deceleration.
Stop all motion, or any selected type of motion, on the selected
physical or imaginary axis or interpolator. Except when used to
perform an Emergency Stop, this block does not disable feedback.
