Description
The output is closed when Speed Select (page 106) = Secondary or Speed Select = BIN.INPUT and
corresponding BI SECOND RPM (PAGE 180) RPM is closed. This logical output (Source) can be configured
to corresponding J1939 output (e.g. Frequency Select in Volvo-IndustrialD12 Aux) see an example below.
Function of Speed select implemented in InteliDrive DCU has no influence on Speed Request by default
setting. Logical binary output Second RPM Sw is normally used to select the rated speed, where the exact
settings depend on the connected ECU. There is still combination of rated speed + additional speed request.
Example: As a study case, we use controller with ECU protocol Scania S6 where command is
through Nominal Speed Offset (proprietary DLN1 message) and for selection of rated speed can be
used signal Nominal speed switch 1 and 2.
Example:
Nominal speed at full load: 1500 rpm
Min offset: -50 rpm
Max offset: +50 rpm
"Nominal speed offset" = 0 × 3A = 58 % => speed offset = +8 rpm
Referens speed to governor at full load = 1500 + 8 = 1508 rpm
