The machine is moved the distance set for this
parameter after a valid zero point pulse is detected
and then stops when returning to the zero point using
an OW††20: Motion Command Code. The final
point is set as the zero point of the coordinate sys-
tem.
• Unit: Reference unit
0
45 Override (OV) OW††2C 0 to 32767 Set the override for the output speed as a percentage
of the OL††22: Rapid Traverse Speed in 0.01%
units.
For interpolation related commands, set override in
the register specified in the Group Definition Win-
dow.
