Description
Output Value of Loadsharing functional block inside ID-DCU Industrial controller. It is RQSP Ramp (page
261) influenced by loadsharing variation signal (this signal can increase / decrease the RQSP Ramp value
by ±1.5 %). The ThrottlePos value is intended to send as required speed to an engine. Load sharing block
diagram.
See following chart describing ThrottlePos value in Running and Loadsharing state.
Note: The regulation speed of loadsharing variation signal (max 1.5 %) is given by PI loop parameters
Load Gain (page 138) and Load Int (page 138) . The Loadsharing: ThrottlePos value is influenced by
ramping specified by Loadsharing: RQSP Ramp setpoint.
Note: The Loadsharing state can be activated from Running state and if both following conditions are
met:
Actual Engine speed is in range specified by setpoints ClutchMinSpeed (page 139) and
ClutchMaxSpeed (page 139)

There is loadsharing activation delay specified by setpoint Loadsharing: Clutch Del to postpone
loadsharing regulation after transient events after engine mechanical connection to gear-box.
Note: It is essential requirement to configure engine load information (ECU value “actual load”, physical
analog input reading actuator position feedback or boost pressure etc.) into E

for loadsharing functionality.
Note: All ID-DCU Industrial controllers working in the same loadsharing group have to be interconnected
on CAN2 bus, controllers must have different controller addresses.
Note: Loadsharing state - the Loadsharing: Back Up Speed value is taken into account instead of Speed
