(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 (

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
