A.005 PID-Encoder Sync
(PID encoder syncronism)
The function syncronizes the updating time of the PID regulator, with the ones of the encoder feedback reading.
A.005 = 0 Disable
The function is not enabled. Setting to parameter
PID update time
(A.008).
A.005 =1 Enable
The function is enabled. Setting of parameter
A.008
has no effect PID regulation
will be updated according to
I.504
.
A.006 PID err sign rev
(PID error signal reverse)
It allows to invert the polarity of the error signal between the reference and the feed-back (as consequence also
the regulation effect is modified).
A.007 PID Integ Init en
(PID integral initializzation enabling)
The function allows to initialize the integral parts at the RUN command or during the passage from gains
setting 1 to gains setting 2. This allows to avoid abrupt oscillation of the regulator output.
When the function is active, the value of the integral component, will take on a value equal to:
Iinit = Pid output - ( (Kp x err) + (Kd x
D
err)
.
A.008 PID update time
It defines the updating time of the PID regulator. The value 0.00 means minimum updating time (5ms).
