Data ZR

[Function] Assign the inverse tangent of the data specified in operand 2 to the variable specified in

operand 1.

The output will turn ON when the operation result becomes 0.

The setting in operand 1 must be a real variable in a range of 100 to 199, 1100 to 1199,

300 to 399 or 1300 to 1399.

The unit of inverse tangent is radian.

(Note 1)

Radian = Angle x Sy 180

[Example 1] ATN 100 1 Assign the inverse tangent of 1 (0.785398) to

variable 100.

[Example 2] LET 1 100

LET 101 1

ATN *1 *101

Assign 100 to variable 1.

Assign 1 to variable 101.

Assign the inverse tangent of the content of variable

101 (0.785398) to the content of variable 1 (variable

100).
