Turntable operation function
 When "No limit (01)" is selected for "Position control mode selection [P075]", the rotation
direction is determined so as to take the shortest movement distance from the current position
to the target position, for usage such as the turntable shown in the figure below.
 Set the amount of movement for one rotation of the rotation coordinates to "Position set-point 0
[P060]", and set the target position of actual operation to "Position set-points 1 to 7 ([P061] to
[P067])".
 This function is enabled when the "Pulse input mode selection [P004]" is "Single phase pulse
input (00)" or "90 degrees shift pulse (01)". Do not use this function when "Forward and reverse
command and pulse (03)" is specified.
 If [P075] is set to "No limit (01)", the homing function, the current position preset function, and
the speed/position switching function cannot be used.
