High-speed zero point return operation
In a high-speed zero point return, positioning is carried out by a machine zero
point return to the " Md.43 Zero point absolute position" stored in the AD75.
The following shows the operation during a high-speed zero point return start.
1) The high-speed zero point return is started.
2) Positioning control begins to the " Md.43 Zero point absolute position",
following the direction and speed set in the zero point return parameters
( Pr.45 to Pr.58 ).
3) The high-speed zero point return is completed.
* The " Pr.47 Zero point address" is a fixed value set by the user, but the
" Md.43 Zero point absolute position" is constantly changed by the AD75 to
indicate the "zero point", even if there is a change in the address information.
