Hello.
I have a small question.
My colleague works with MDX61B.
DFE32B card inserted in MOVIDRIVE MDX61B.
My colleague already had experience with MDX61B in the same configuration.
Frequency converter is controlled through Profinet.
A colleague can control the motor, a colleague reads data from a frequency converter and writes data to a frequency converter.
He has only one problem.

He sees the letter "t" (Inverter is waiting for data), on the 7-segment display.

Any ideas?

Thanks.
 
t = Inverter is waiting for data
If the inverter is controlled via a communication interface (fieldbus, RS485 or SBus) and
the power was switched off and back on again or a fault reset was performed, then the
enable remains ineffective until the inverter receives valid data again via the interface,
which is monitored with a timeout.

Is it possible that a timeout interval has been configured for a communication interface that is not used?

Check P812 or P883

Hello.
Thanks for the answer.
My colleague removed the internal card DFE32 (Feldbus) and connected it to another external (not integrated) DFE32 (Sbis1).
With this connection there are no errors.
Previously in other projects, with this configuration (the internal card DFE32 (Feldbus)), there were no errors.
This is not the first project of my colleague with this configuration.
Maybe later he will check again.
Thanks again.

P812 and P883 timeout parameters for RS485 and SBus.
My colleagues have an error when the FIELDBUS interface is selected.
Is there a timeout parameter for FIELDBUS?
