A.003 PID digital ref
(PID digital reference)
Setting of the reference for the PID function.
It will be active only if
PID Fbk sel
(A.002)
is set as 6
A.004 PID activate mode
It defines if the PID function has to always be enabled or if it has active in steandy state only.
A.004 = 0 Always
The PID function is always enabled.
A.004 = 1 Steady state
The PID function is enabled only at steady state.
