(3) Since the upper and lower limit values of the positioning address calculated
are outside of the range of Condition 2, use the positioning address within the
positioning range of Condition 2 (-2147483648 (µm) to 2147483647 (µm)).

•
The positioning address is within the range 0° to 359.99999° at the position
to which a machine OPR was made.
When the OP position is not 0°, the range is also 0° to 359.99999°.
•
For positioning in the same direction, control from maximum to minimum
(for address increase: 359.99999° to 0°/for address decrease: 0° to
359.99999°) cannot be exercised. (See below)
