1.15.3 PID Input Block (PID Input)
The Block calculates the error value of the PID Block.
Two input references are selected via an internal selector.
On the selected reference it is possible to set a Ramp and to add an additional reference, Pid Draw.
It is also possible to limit the output error value at the machine start and to select a command for the reaction
of the PID section.
The PID set 0 src and PID set 1 src
sources select the signal origin of the two input references:
PID seloff 0 src selects the command of the internal selector, PID draw src selects the additional reference
signal and PID fbk src selects the reaction command of the PID section.
In the
configurations it is possible to set the variable internal values, with PID gain draw to adapt the error gain,
with PID acc time and PID dec time to set the reference ramp and with PID clamp top and PID clamp bot to set
the upper and lower limit (see the paragraph Dynamic Clamp).
The inputs are: · PID fbk src
· PID draw src
· PID set 0 src
· PID set 1 src
· PID seloff 0 src
