DESCRIPTION
This command defines the value that is loaded in the position counter when home
is found. The default value for all motion devices is 0. This means that unless a
new value is defined using this command, the home position will be set to 0
when a home search is initiated using the OR command or from the front panel
(if available).
Note:
The change takes effect only when a subsequent home search routine is
performed. To make the change permanent, use the SM command to save it in
the non-volatile memory.
RETURNS
If the “?” sign takes the place of nn value, this command reports the current
setting.
