This setpoint adjusts the frequency of the speed governor output in PWM mode.
The PWM mode of the speed governor output is activated by the jumper located
next to the speed governor output terminals.
The PWM interface is used for several governor types as e.g. CAT or Cummins.
Adjust the PWM frequency according to the governor specification. Adjust the
setpoint to 1200Hz if the PWM interface is not used.
Setpoint: SpeedGovLowLim
-10.00 .. SpeedGovHiLim [V]
Lower limit of the speed governor output. Use this setpoint to adapt the governor
output range to the input range of your governor.
Setpoint: SpeedGovHiLim
SpeedGovLowLim .. 10.00 [V]
Upper limit of the speed governor output. Use this setpoint to adapt the governor
output range to the input range of your governor.
Setpoint: TauSpeedActuat
This setpoint is used to adjust the trasformation ratio of the speed governor output
to the pulses at the binary outputs Speed up and Speed dn. Adjust the setpoint to
the pulse duration which is needed for the speed control device to travel from
minimal position to the maximal position.
Setpoint: Load Ramp
All changes of requested gen-set load (except in loadsharing mode) are not made
as one step, but are ramped - i.e. the requested load is changing slowly with the
