3.5.8 Y.SRC Assignment of continuous-action output

This function enables you to determine whether the continuous-action output is used as control-
ler output (PID output) or assigned to the inputs X or WE, or to error. Optionally, the signals can
then be transferred to a recorder.
The Y.XD setting allows the error XD in the range 0 to 100 % to be issued at the output.
If the range –100 to 100 % is to be issued at the output, the CALC mathematical adaption must
be activated (on CA.Y) and the parameters must be set as follows:
CA.K1 = 100.0, CA.K2 = 0.5, CA.K3 = 100.0

3.5.9 CALC Mathematical adaption of continuous output

This function enables you to mathematically modify the continuous-action output to set it up for
a recorder, for example. The following formula applies:
YOUT = ±(Y – CA.K1) CA.K2 + CA.K3

Mathematical adaptation with positive sign
+ (Y – CA.K1) CA.K2 + CA.K3. Whereby, (Y – CA.K1) ≥ 0 applies
Mathematical adaptation with negative sign
– (Y – CA.K1) CA.K2 + CA.K3. Whereby, (Y – CA.K1) ≥ 0 applies
Mathematical adaptation without condition
(Y – CA.K1) CA.K2 + CA.K3.
