07 LOWER LIMIT - REF:
[*20.0 (0, 100)] This menu item defines the lower limit of the off-
line/isochronous speed reference.
08 ENABLE SDR INVERS:
[*TRUE or FALSE] This menu item can be used to disable the inversion of
the SDR during starts and load rejections. This should be left TRUE unless stability problems are being
experienced during starts and load rejections.
09 PID CLAMP WIN +/-:
[*4 (0,5)] This menu item defines the window size for the PID clamp.
16 ONLINE/DROOP CTRL
This menu contains items related to on-line droop control.
01 SPEED ADJUST:
[MONITOR] This menu item displays the droop speed reference.
02 I'M IN CONTROL:
[MONITOR] This menu item displays a TRUE when the on-line/droop speed control
algorithms are in control.
03 GATE POS SET POINT:
[MONITOR] This menu item displays the on-line/ droop gate position set
point.
04 PID OUTPUT:
[MONITOR] This menu item displays the on-line/droop PID controller output.
05 RAISE/LOWER RATE:
[*0.1 (0,1000)] This menu item defines the rate at which the on-line/droop
RAISE and LOWER commands adjust the droop speed reference.
06 SET POINT DERIV TC:
[*0.96 (0.001,5)] This menu item defines the time constant for the set point
derivative calculation. This number should be left at 0.96, unless problems are experienced with the Feed
Forward control.
07 PID CLAMP WIN +/-:
[*4 (0,5)] This menu item defines the window size for the PID clamp.
17 REMOTE CONTROL
This menu contains items related to remote control.
01 REM SPD ENABLED:
[MONITOR] This menu item displays when remote speed control is enabled.
02 REM SPD ANLG IN ENABLED:
[MONITOR] It displays if the accepted remote speed value will be
from analog input
03 RMT SPD ANALOG IN:
[MONITOR] It displays the value of the Remote Control analog input (scaled)
04 REM SPD MODBUS ENABLED
: [MONITOR] It displays if the accepted remote speed value will be
from Modbus
05 REMOTE SPD REFERENCE
:[MONITOR] Is displays the actual value of the Remote speed reference
06 AI VALUE @ 4 mA
:[*0(-200,200)] Configure the value of the Remote reference when the current input
is 4 mA
07 AI VALUE @ 20 mA
:[*100(-200,200)] Configure the value of the Remote reference when the current
input is 20 mA
08 REMOTE SPEED RAMP RATE
: [*0.2 (0.0, 100.0)] This parameter defines the rate of change (in %/s)
that the online ramp is changed when there is a change in the remote setpoint.
18 LEVEL CONTROL
It contains items related to the Pond/Tail level control function.
01 LVL CNTRL ENABLED:
[MONITOR] This menu item displays TRUE when level control is enabled.
02 POND/TAIL LEVEL:
[MONITOR] This menu item displays the pond/tail level.
03 LEVEL SET POINT:
[MONITOR] This menu item displays the level set point.
04 PRESET VALUE:
[*0 (0,100000)] This menu item defines the pond/tail level preset set point. This
value is only used if Level control is configured to go to a preset set point each time level control is
enabled. If the level control set point is configur
ed to “follow” the actual level, then this menu item is not
used.
05 MAX GATE POSITION:
[*100 (0,100)] This menu item defines the maximum gate position allowed
when controlling pond or tail level. The units of this value are gate position percent (%).
06 MIN GATE POSITION:
[*20 (0,100)] This menu item defines the minimum gate position allowed when
controlling pond or tail level. The units of this value are gate position percent (%).
07 CONTROL WINDOW:
[*0.5 (0,10000)] This menu item defines the desired accuracy of the pond/tail
level control circuit. This smaller this window is set for, the more the wicket gates will move to control the
level. See Chapter 3.
08 GATE POSITION SET:
[MONITOR] This menu item displays the gate position set point resulting from
the level control algorithm.
