VLT Parameters
Pay particular attention to the following parameters when configuring an FC 300 with a PROFIBUS interface.
•
Par. 0-40
[Hand on] key on LCP
. If the Hand button on the FC 300 is activated, control of the drive
via the PROFIBUS interface is disabled
•
After an initial power up the FC 300 will automatically detect whether a fieldbus option is installed in
slot A, and set par. 8-02
Control word source
to [Option A]. If an option is added or changed in or
removed from an already commissioned drive, it will not change par. 8-02 but enter Trip Mode, and
the drive will display an error
•
Par. 8-10
Control word profile

•
Par. 8-50 to 8-56. Selection of how to gate PROFIBUS control commands with digital input command of
the control card
NB!:
When par. 8-01
Control Site
is set to [2]
Control word only
, then the settings in par. 8-50 to 8-56

Diagnosis trigger
LEDs
The two bi-colour LEDs in the PROFIBUS card
indicate the status of PROFIBUS communication
The LED marked “NS” indicates the network status,
i.e. the cyclical communication to the PROFIBUS
master. When this light shows constant green, then
data exchange between the master and the FC 300
is active.
The LED marked “MS” indicates the module status,
i.e. acyclical DP V1 communication from either a
PROFIBUS master class 1 (PLC) or a master class 2
(MCT 10, FDT tool). When this light shows constant
green, then DP V1 communication from master
classes 1 and 2 is active.
For details of the full range of communications
status indicated by the LEDs, please refer to the
Troubleshooting
chapter.
