Communication is working but BFI-E3…-MTP doesn’t run the motor correct:
-
Software enable bridge between terminal 1 and 2 in place?
-
BFI-E3…-MTP is powered up?
-
No alarm in BFI-E3…-MTP?
-
Parameter P-12 set to 3 or 4 in BFI-E3…-MTP?
-
Variable Ready to Run must be 1 to run the BFI-E3
-
Stop in display?
o
Start signal by bus is missing. As soon as BFI receives a start signal a value
between 0 and Maximum speed is displayed instead of Stop.
-
H 0.0 in display?
Start signal arrived but no speed setpoint
o
Speed sent to BFI-E3 must be a value between parameter value P1-01 and P1-02.
o
Speed into Function block is a REAL. Value 50.0 Hz means value 500 being sent
to BFI-E3
o
Check that sent speed by bus corresponds with value in P0-03 in BFI-E3.
