427 U3 voltage
Value:
0.0 - 999.0 V
par. 103
Function:
See parameter 423
U1 voltage
.
Description of choice:
Set the output voltage (U3) that is to match the third
output frequency (F3), parameter 428
F3 frequency .
428 F3 frequency
Value:
Par. 426 F2 frequency - 1000 Hz
Par. 104
Motor
frequency
Function:
See parameter 423 U1 voltage .
Description of choice:
Set the output frequency (F3) that is to match the third
output voltage (U3), parameter 427
U3 voltage .
NOTE:
Parameters 437-444 are only used if in parameter 100
Configuration a selection has been made of Process
regulation, closed loop. [3].
437 Process PID normal/inverse control
Value:
Normal (normal) [0]
Inverse (inverse) [1]
Function:
It is possible to choose whether the process regulator
is to increase/reduce the output frequency if there is
a deviation between the reference/setpoint and the
actual process mode.
Description of choice:
If the adjustable frequency drive is to reduce the out-
put frequency in case the feedback signal increases,
select
Normal [0].If the adjustable frequency drive is
to increase the output frequency in case the feedback
signal increases, select
Inverse [1].
438 Proces PID anti windup
Value:
Not active (DISABLE) [0]
Active (ENABLE) [1]
Function:
It is possible to select whether the process regulator
is to continue regulating on a deviation even if it is
not possible to increase/reduce the output frequency.
Description of choice:
The factory setting is Enable [1], which means that the
integration link is initialised in relation to the actual
output frequency if either the current limit, the volt-
age limit or the max./min. frequency has been
reached. The process regulator will not engage again
until either the error is zero or its sign has changed.
Select
Disable
[0] if the integrator is to continue inte-
grating on the deviation, even if it is not possible to
remove the fault by such control.
NOTE:
If
Disable [0] is selected, it will mean that when the
deviation changes its sign, the integrator will first
have to integrate down from the level obtained as a
result of the former error, before any change in out-
put frequency occurs.
439 Process PID start frequency
Value:
f MIN - f MAX (pa-
rameter 201/202)
Par. 201 Output frequency,
low limit, f MIN
Function:
When the start signal comes, the adjustable frequen-
cy drive will react in the form of
Open loop and will not
change to Closed loop until the programmed start fre-
quency is reached. This makes it possible to set a
frequency that corresponds to the speed at which the
process normally runs, which will enable the required
process conditions to be reached sooner.
Description of choice:
Set the required start frequency.
NOTE:
If the adjustable frequency drive is running a the cur-
rent limit before the required start frequency is ob-
tained, the process regulator will not be activated. For
the regulator to be activated anyway, the start fre-
quency must be lower to the required output fre-
quency. This can be done during operation.
440 Proces PID proportioanl gain
Value:
0.0 - 10.00
0.01
Function:
The proportional gain indicates the number of times
the deviation between the setpoint and the feedback
signal is to be applied.
Description of choice:
Quick regulation is obtained by a high gain, but if the
gain is too high, the process may become unstable
due to overshoot.
