Wiring procedure for VLT
®
DriveMotor FCP 106
1. Mount the fieldbus connector on the fieldbus
option (terminals 62, 63, 66, and 67).
2. Prepare the fieldbus cable by stripping a section
of the cable insulation, so that the cable screen is
in contact with the EMC bracket. Keep the
unshielded wire as short as possible. For cable
specifications, refer to
chapter 3.7.2 Cable Specifi-
cations . For fieldbus cable requirements, see
chapter 3.7.3 Bus Segment Requirements .
3. Connect the fieldbus cable wires to the terminals
according to the colour code of the wires, see
Illustration 3.10 .
4. To establish mechanical fixation and electrical
contact between cable screen and ground,
position the stripped cable between the spring
loaded metal clamps.

1. If the address has not been set via the address
switches, go to
parameter 9-18 Node Address to
set the address.
2. Connect to a running PROFIBUS master.
3. Check that network cabling is correct:
3a Check that the net status LED flashes
green in any pattern, except
search baud
rate , see Table 4.2 .
3b Check if parameter 9-63 Actual Baud Rate
shows the same baud rate as the
PROFIBUS master.
