When setting cruise control, COMPACT's EasyCalib function should be used as much as possible. However, if this does not work, refer to the manual procedure or to the values in the document attached to this application note.
Speed/voltage control
The module allows you to control speed or voltage with the following options:
- Correction with two analog signals (speed and voltage) +/- 10VDC with adjustable amplitude and offset.
- Correction with pulse output (+speed/speed and +voltage/voltage).
- Correction with J1939 frames for speed only.
[4404] is the speed/KW correction applied to the speed controller (value given in percent).
[4408] is the voltage/KVAR correction applied to the voltage regulator (value given in percent).
Speed/voltage controlled by analog outputs :
The speed output sets the frequency setpoint required by the speed controller during synchronization and kW control (load sharing, ballasting ramp). The full range of this output is -10V...10VDC and must be adjusted in amplitude and offset to control motor speed within +/- 2.5Hz of the nominal frequency.
The voltage output sets the voltage setpoint required by the voltage regulator during voltage synchronization and reactive load sharing. The full range of this output is -10V...10VDC and must be adjusted in amplitude and offset to control the alternator voltage within a range of +/-30V around the nominal phase-to-phase voltage.
