Find Home search.
Description
xxOR
Syntax
This command is used to execute a home search routine for an axis. The controller will
Remarks
automatically stop the axis after crossing the index. If this command is issued when an axis'
motion is in progress, the controller will ignore this command and generate "MOTION IN
PROGRESS" error message.
The controller executes a unique sequence of motion in order to locate and finally stop the
positioner at a repeatable Home position. The repeatability precision depends mostly on the
repeatability of the Home switch itself and ability to stop and hold final position. It is not
unusual for a Find Home function to be repeatable to within 20 encoder counts (e.g., 8410-V
positioner).
Issue the Define Home (DH) command after OR completed to make Home position the
reference for Position Absolute (PA) commands.
The Home search motion status can be monitored using the Motion Done (MD?) command.
NOTE: The controller will NOT stop motion until it finds the Home signal transition.
NOTE: The Find Home function is compatible with 8310-V positioner.
NOTE: The Find Home function is NOT compatible with 8310 and 8410 positioners.
