5-1-4 Commissioning Mode
!Caution

Possible Cause(s)
The PROFIBUS configuration is NOT correct,
but the PROFIBUS master can communicate
with the Option Board.
The network error action (selected with param-
eter P045) was executed due to a PROFIBUS
network error.
If the Option Board is operating in commissioning mode, the RUN indicator
will flash.
Commissioning mode is NOT an error, but it can influence normal system
operation. During commissioning mode, Inverter parameter access takes pri-
ority over cyclic data exchange. Accessing Inverter parameters will therefore
delay cyclic data exchange causing unexpected latencies.
If you are not busy configuring the Option Board or drive parameters, disable
commissioning mode by writing a 0 (zero) to PNU890.
Make sure that you disable commissioning mode before operating the system.
Corrective Action
Check (and correct) the following items:
• Does the node address of any OTHER
slave device on the PROFIBUS network
match P180?
• Are you using the correct GSD file in your
PROFIBUS master configuration
gram?
• Does the device profile (P182) support the
configured module in your PROFIBUS
master configuration program (Refer to 3-1
Configuring the Option Board)?
Check (and correct) the following items:
• Is the PROFIBUS master faulty, switched
off or off-line?
• Are the PROFIBUS connectors on both
the Option Board and master properly
connected?
• Has anything changed on the PROFIBUS
network (devices, termination, connectors,
etc.)?
• Are there any short circuits or line interrup-
tions?
