S4.3 NOMINAL
The Required speed is set to Nominal RPM if the Nominal input is closed, otherwise is the Request
set to Idle RPM.
S4.4 SPEED UP
Inputs SPEED UP and SPEED DOWN are used for setting of the speed reference of the engine. The
speed reference can be changed in the range from Nominal RPM - PerChSpdNom% to Nominal RPM
+ PerChSpdNom%. Setpoint: EngineRPM:PerChSpdNom [1-50%] defines the maximum Percentage
change of Speed from Nominal in case BIN or ANA mode of control is used.
Setpoint BI Speed ramp decides how fast the speed reference changes, if the inputs SPEED UP or
SPEED DOWN are active.
Hint:
Inputs SPEED UP and SPEED DOWN are active only if the setpoint Speed request has value BIN.

S4.6 RUN
If the input is not active, governor immediately set the actuator to stop position.
