2.4.50.1 Control characteristic
In the default setting, the PID algorithm is active.
l The D component is deactivated with
– C0224 = 0 for PCTRL1,
– C1334 = 0 for PCTRL2.
l The I−component is switched on or off online via the PCTRLx−I−OFF input. For this, the input is
assigned a digital signal source (e.g. one of the freely assignable digital input terminals). If the
I−component is to be switched off permanently, the input is assigned the signal source
FIXED1.
– PCTRLx−I−OFF = HIGH switches off the I−component.
– PCTRLx−I−OFF = LOW switches on the I−component.
l The adjustment time T
n
is parameterized via
– C0223 for PCTRL1,
– C1333 for PCTRL2.
Gain V
p
for PCTRL1
You can adapt the gain V
p
in different ways. The function for the provision of the gain V
p
is selected
under C0329:
l C0329 = 0
– The gain V
p
is entered under C0222.
l C0329 = 1
– The gain V
p
is entered using the input PCTRL1−ADAPT. The input value is led via a linear
characteristic. The shape of the characteristic is set under C0222 (upper limit) and C0325
(lower limit). The value under C0222 is valid if the input value = +100 % or −100 %. The
value under C0325 is valid if the input value = 0 %.
