Use Enable in parameter 6246/6256/6266 to select the derate characteristic:
• Enable OFF: Inverse. A higher control value gives a lower power.
• Enable ON: Proportional. A higher control value gives a higher power.
6.7.4 EIC derate
INFO
This requires option H12.
The AGC can use a value from the EIC for derating. Specifically, the AGC uses the Engine Derate Request (PGN 64914/0xFD92,
SPN 3644) to calculate the maximum genset power.
There are two options for EIC derating.
