adjustable points on the response curve give the user full flexibility to control non-linear
responses. These functions are adjustable while the controller is running in order to
adjust unknown output characteristics.
* Note – See the DVC710 Programming User Guide for more details.
LOCALIZED CLOSED LOOP FUNCTIONS
All inputs have the ability to be used in a closed loop configuration with the outputs
locally. Most closed loop configurations such as speed and rpm control require very fast
response times. Closing the loop locally, instead of over the CAN Bus on the Master
Module, will result in the response needed for these configurations.
COMMUNICATIONS
A. The DVC750 has two communication ports:
1
Can Bus 2.0B – This port is used to communicate to other DVC modules
as well as an ECM (engine control module).
