(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 (m) to 2147483647 (m)).

2.Concept for the unit of degree

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)

Usable range in absolute position detection system (0 ~ 359.99999)

When positioning is to be used in the absolute position detection system, set the upper and lower limit values of the software stroke limit within the range 0° to 359.99999° .
