Changing the offset value in the parameter block has no effect on the two
move blocks already stored on board the 1771-ES expander module, but
only on subsequent move blocks.

Bits 11, 10, 06 Set to 100 Preset to Position

Turn bit 11 on, bit 10 off, and bit 06 off to generate a preset to position.
This command clears the accumulator register to zero and sets the
position register to the value specified in the position words. Instead of
generating axis motion, this command redefines the present axis position.

Bits 11, 10, 06 Set to 110 Dwell

Turn bit 11 on, bit 10 on, and bit 06 off to generate a dwell. This
command inhibits the 1771-ES expander from executing the move block
