ECON-4 1.4.0 Global Guide
14
Binary inputs are used to control the function of the ECON-4 digital governor.
Binary inputs can be read from:
the physical Binary inputs (terminals S4.x),
from the CAN-bus (byte Command in the Receive PDO),
in dependence on the value of the setpoint Speed request.

Note:
Cmd.x is bit x in the byte Command of the Receive PDO, see description of CAN protocol. S4.x
isECON-4 terminal. Both the physical Binary input S4.6 and the corresponding bit Cmd.3 received via
CANbus must be active to activate Binary input RUN in DATA mode. In case of lost communication on
CANbus, all bits of the byte Command are set to 0 – it deactivates
MCB fdb (S4.1)
Inputs GCB and MCB fdb decide which setpoints are used in PID speed regulation loop and which type of
regulation is used (Iddle/Island/Parallel):

There is more Load gain and Load der values in ECON-4 ADV. Which set will be used depends on actuall
power.
