This mode can be used only when the coordinate is set to rotary coordinate.
If the distance has a positive value, the motor rotates in the positive direction, and
if the distance has a negative value, the motor rotates in the negative direction.
Distance may be set to above one cycle (the value set for Modulo Factor: 0x240C),
and depending on the command value, the motor may rotate more than 1 cycle.
