21-00 Closed Loop Type
Option: Function:
This parameter defines the application response. The default mode should be sufficient for most
applications. If the relative application speed is known, it can be selected here. This will decrease
the time needed for carrying out PID Autotuning. The setting has no impact on the value of the
tuned parameters and is used only for the PID auto-tuning sequence.
[0] * Auto
[1] Fast Pressure
[2] Slow Pressure
[3] Fast Temperature
[4] Slow Temperature
21-01 PID Performance
Option: Function:
[0] * Normal Normal setting of this parameter will be suitable for pressure control in fan systems.
[1] Fast Fast setting would generally be used in pumping systems, where a faster control response is de-
sirable.
21-02 PID Output Change
Range: Function:
0.10 N/A* [0.01 - 0.50 N/A] This parameter sets the magnitude of step change during autotuning. The value is a percentage of
full operating range. I.e. if maximum analog output voltage is set to 10 V, 0.10 is 10% of 10 V,
which is 1 V. This parameter should be set to a value resulting in feedback changes of between
10% and 20% for best tuning accuracy.
21-03 Minimum Feedback Level
Range: Function:
-999999.00
0 N/A* [-999999.999 - par. 21-04 N/A] The minimum allowable feedback level should be entered here in User Units as defined in par.
21-10
Ext. 1 Ref./Feedback Unit
for EXT CL 1, par.21-30
Ext. 2 Ref./Feedback Unit
for EXT CL 2 or
par.21-50
Ext. 3 Ref./Feedback Unit
for EXT CL 3. If the level falls below par.21-03
Minimum Feed-
back Level
, PID autotuning is aborted and an error message will appear on the LCP.
21-04 Maximum Feedback Level
Range: Function:
999999.000
N/A* [par. 21-03 - 999999.999 N/A] The maximum allowable feedback level should be entered here in User units as defined in par.
21-10
Ext. 1 Ref./Feedback Unit for EXT CL 1, par.21-30 Ext. 2 Ref./Feedback Unit for EXT CL 2 or
par.21-50 Ext. 3 Ref./Feedback Unit for EXT CL 3 If the level rises above par.21-04 Maximum Feed-
back Level , PID autotuning is aborted and an error message will appear on the LCP.
21-09 PID Autotuning
Option: Function:
This parameter enables selection of the Extended PID controller to be autotuned and starts the PID
autotuning for that controller. Once the autotuning has successfully completed and the settings have
been accepted or rejected by the user, by pressing [OK] or [Cancel] buttons on the LCP at the end
of tuning, this parameter is reset to [0] Disabled.
[0] * Disabled
[1] Enabled Ext CL 1 PID
[2] Enabled Ext CL 2 PID
[3] Enabled Ext CL 3 PID
