Description
P_01 Nominal Speed
rpm
1000
2000
1500
This parameter defines the nominal
(target) speed of the engine.
P_02 Idle Speed
rpm
500
1500
900
This parameter defines the idle speed
of the engine when idle input is active.
P_03 Delayed
Overspeed Limit
%
105
200
110
If the engine rpm goes over this limit
during overspeed delay timer (P_05),
this will generate an overspeed alarm.
P_04 Immediate
Overspeed Limit
%
110
200
120
If the engine rpm goes over this limit,
this will generate an overspeed alarm.
P_05 Overspeed Delay
Timer
sec
1
10
5
If the engine rpm goes over P_03
during this timer, this will generate an
overspeed alarm.
P_06 Cranking rpm
rpm
0
300
10
During engine cranking, if the rpm is
above this limit, the unit activates the
actuator output. (P_09)
P_07 Running rpm
rpm
300
1000
400
This parameter is the limit to start speed
ramping with PID control.
P_08 Crank Teeth Count
-
2
500
100
This parameter defines the flywheel
teeth number of engine. If alternator
voltage is used for speed sensing, this
paramet
er should be set to “
2
”.
P_09 Starting RPM Fuel
%
5
100
45
This parameter defines the amount of
actuator output during cranking.
P_10 Running RPM Fuel
%
0
100
50
This parameter defines the amount of
actuator output when the engine has
fired. It is calculated as a percentage of
parameter P_09.
P_11 Speed Ramping
rpm
Rpm /
sec
10
9999
200
This parameter defines the value of the
speed ramping in rpm/sec.
P_12 Low Battery
Voltage
Vdc
2
30
8
This parameter defines the low battery
voltage alarm limit.
P_13 Global Gain
-
1
9000
20
This parameter governs the nominal
rpm catching of the controller.
If this parameter is increased, the
operation will be faster but unstable. If it
is decreased, the operation will be
slower but more stable. The optimal
setting is the fastest stable operation.
P_14 P Gain
-
0
9999
100
Proportional gain.
P_15 I Gain
-
0
9999
50
Integral gain.
P_16 D Gain
-
0
9999
40
Derivative gain.
P_17 Aux Enable
-
0
1
0
0: Aux input disabled
1: Aux input enabled
P_18 Aux Speed
rpm
10
300
300
This parameter defines the value of
speed change when aux is enabled.
P_19 Droop Gain
% / A
0.1
10
4
This is the parameter to adjust the
amount of droop.
P_20 Trim Enable
-
0
1
0
This is the parameter to enable speed
control with external potentiometer.
0: External speed trim disabled
1: External speed trim enabled
P_21 Trim Gain
%
5
20
10
This is the percentage of running rpm to
adjust the engine speed with external
potentiometer.
