Optimum performance is not necessarily obtained with the GAIN set
to maximum (stable). In some cases, the gain must be reduced
slightly to ensure stability under widely-varying conditions.
Be prepared to change the dynamics settings since the actuator
bump transient may stimulate instability.
BUMP ENABLE must be set TRUE to enable the BUMP ACT function.
See the ACTUATOR BUMP SETUP menu.
I**Dynamics #2**
The Dynamics 2 control parameters are adjusted the same as Dynamics 1
described above. To enable the use of two sets of dynamics, it is necessary to
set Enable 2nd DYNAMICS w/CB below to TRUE. These parameters are in
control only when the CB Aux contact input is closed or if a discrete input is
configured for Select 2
nd
Dynamics and this input is closed.
I**Dynamics #2** parameters 04 thru 10 have the same effect on
speed control response as H**Dynamics #1** parameters 01 thru 07
described above.
01 ENABLE DYNAMICS 2 W/CB dflt = FALSE (FALSE, TRUE)
02 DELAY DYN 2 ENABLE (SEC) dflt = 0.00 (0.00, 20.00)
This is the delay time before dynamics #2 are used by the speed control when
the "CB Aux Droop contact" or "Select 2nd Dynamics" input is activated.
03 DELAY DYN 1 ENABLE (SEC) dflt = 0.00 (0.00, 20.00)
This is the delay time before Dynamics #1 are used by the speed control after the
"CB Aux Droop contact" or "Select 2nd Dynamics" input is de-activated.
04 PROP GAIN 2 dflt = 4.00 (0.01, 100.00)
05 RESET 2 dflt = 2.00 (0.01, 100.00)
06 ACTUATOR COMPENSATION 2 dflt = 12.00 (0.01, 100.00)
07 WINDOW WIDTH 2 (RPM) dflt = 60.00 (1.00, 200.00)
08 GAIN RATIO 2 dflt = 1.00 (1.00, 10.00)
09 SPEED FILTER FREQ 2 (HZ) dflt = 20.00 (4.00, 20.00)
10 BUMP ACT TRIG (T THEN F) dflt = FALSE (FALSE, TRUE)
