Processing details
■Operation processing
• These functions calculate the cosine of the angle of the REAL type data input to (s), and output from (d).
• These functions are expressed as follows when the input value is "A" and the output operation result is "B".
B=COS A
• A value (angle) input to (s) is the REAL type data value. Input a value in radians (angle/180).
■Operation result
1.
Function without EN/ENO
The following table lists the operation results.
Operation result
No operation error occurred
An operation error occurred
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
Error code Description
(SD0/SD8067)
3402 A negative value is input.
