P522
0.000 to 9.999
PID Differential
[ 0.000
]
Gain
0.001
The integral gain can be defined as being the time
required to change thePI regulator outputfrom0 to P134,
that is given, in seconds, by the equation below:
For the following conditions:
-
P040 = P520 = 0.
-
DI3 in automatic position.
P525
0.00 to 100.0
Setpoint (via
[ 0.00
]
Keypad) of the
0.01 %
PID Regulator
Provides the setpoint (reference) of the process via
cointrol via the and keys for the PID regulator,
provided that P221 = 0 (local) or P222 = 0 (remote) has
been set to automatic mode. If it has been set to Manual
Mode, the frequency reference is given by P121.
If P120 = 1 (backup active), the value of P525 is
maintained at the lastset value (backup), evenwhen the
inverter is disabled or turned off.
P526
0.01 to 10.00
Process Variable
[ 0.10 s ]
Filter
0.01 s
It sets the time constant of the Process Variable Filter.
It is useful for noise filtering at the analog inputAI1
(feedback of the process variable).
P527
0 or 1
