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
