Description

In the following example, the BCD contents of the 8 words from DM 0000 to
DM 0007 are added when IR 00001 is ON and the result is written to DM 0010
and DM 0011.

For trigonometric functions S must be BCD from 0000 to 0900 (0°≤ q ≤ 90°).
When the execution condition is OFF, APR(69) is not executed. When the exe-
cution condition is ON, the operation of APR(69) depends on the control word C.
If C is #0000 or #0001, APR(69) computes sin(q) or cos(q)*. The BCD value of S
specifies q in tenths of degrees.
If C is an address, APR(69) computes f(x) of the function entered in advance be-
ginning at word C. The function is a series of line segments (which can approxi-
mate a curve) determined by the operator. The BCD or hexadecimal value of S
specifies x.
Indirectly addressed DM word is non-existent. (Content of :DM word is
ER:
not BCD, or the DM area boundary has been exceeded.)
For trigonometric functions, x > 0900. (x is the content of S.)
A constant other than #0000 or #0001 was designated for C.
The linear approximation data is not readable.
EQ: The result is 0000.
