Processing details
■Division processing
This function block divides the values input from the input variables IN1 to IN2 with coefficients and bias and outputs the result
from the output variable OUT_.
Input (IN2), coefficient (K_2), bias (B2_): Denominator
K_2  IN2 + B2_ is not 0 (denominator  0)
K_2  IN2 + B2_ is 0 (denominator = 0)
IN1 to IN2: Input value, A_ and K_1 to K_2: Coefficient, B1_ to B3_: Bias
Operation error
Error code Description
(SD0)
3400H An invalid operation (such as division by zero) is performed.
3402H Input data (IN1 to IN2) or operation constant (A_, K_1, K_2, B1_, B2_, and B3_) is a subnormal number or NaN (not a number).
3403H An overflow has occurred.
6 ARITHMETIC OPERATION

6.4 Division (with coefficient) (M+P_DIV)
Output (OUT_)
K_1×IN1+B1_
OUT_=A_× +B3_
K_2×IN2+B2_
OUT_ = B3_
