override will not start until you close the feedrate-override-enable input.
This allows you to synchronize the feedrate override on several axes.
Bit 7 Search Home Direction
Use bit 7 to specify the direction the axis moves in a search home
operation:
To make the axis move in this direction: Then set bit 17 to:
Negative (Ć)
Positive (+)
0
1
Bit 10 Axis Feedrate Override Enable
Turn on bit 10 to enable feedrate override for the axis.
If this bit is off, feedrate override is disabled for all axis motion. If it is
on, feedrate override is enabled only on those moves for which bit 7 of the
SMCW is on.
Bit 11, 15 Readout Select
The third and fourth status words for an axis provide either current axis
position, following error, or diagnostic information. You can select which
status to display by controlling the state of bits 11 and 15 of axis control
word 2:
Turn off bits 11 and 15 to display the current axis position.
Turn off bit 11 and turn on bit 15 to display the following error.
Turn on bit 11 to display the diagnostic status.
Bit 12 Return to Position
In the manual mode, turn on bit 12 to generate a return-to-position
command. When the servo positioning assembly is in the manual mode
and this bit is on, the axis jogs at the selected jog rate (high or low) to the
position where the axis was last stopped during execution of a moveset.
If the axis had stopped in the middle of a move, the return-to position
command would return the axis to the point where it had stopped, not the
endpoint of the move block.
