8.4.1 Outline of the high-speed zero point return operation
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 D75P2.
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 speed set in the zero point return parameters (
Pr.45 to
Pr.58 ).
3) The high-speed zero point return is completed.
