Bit 7 Allow Feedrate Override
With bit 7 on, you can enable feedrate override for this move by turning
on the axis feedrate override enable bit in the command block. The
programmed feedrate for this move is modified by the feedrate override
value programmed in the command block. Feedrate override value is
typically an operator controlled input.
With bit 7 off, this move executes at the programmed feedrate regardless
of the command block.
This bit affects only the move controlled by the SMCW. For example, if
feedrate override is to apply to several moves, you must turn on bit 7 of
the SMCW for each of those moves.
Bits 11, 10, 06 Set to 000 Move to Position
Turn off bit 11, 10, and 6 to generate a move to position. The axis will
move to the position specified by the sum of the value in the position
words and the value in the offset accumulator register.
Bits 11, 10, 06 Set to 001 Constant Velocity
Turn bit 11 off, bit 10 off, and bit 6 on to generate a constant velocity
move. This command clears the position register to zero before moving
the axis to a position specified by the value in the position words. By
repeatedly generating continuous constant velocity moves you can cause
uninterrupted motion that you could apply to conveyors, winders, coilers
and spindle-type controls.
Bits 11, 10, 06 Set to 010 Move to Position with Offset
Turn bit 11 off, bit 10 on, and bit 06 off to generate a move to position
with offset. This command first adds the offset value in the parameter
block to the offset accumulator register. Then the axis moves to the
position specified by the sum of the value in the position words and the
value in the offset accumulator register.
The endpoints of all following moves are also modified by the offset
value, which remains in the offset accumulator. If you execute the
moveset again, the offset accumulator value increments again when the
move-to-position-with-offset command executes. Figure 7.34 shows the
effect of position with offset.
