Electrical installation
Installation of optional modules and PC
Optional modules (such as fieldbus adapters and I/O extension modules) are
inserted into the optional module slot of the RMIO boards (built in the RDCU drive
control units) and secured with two screws
. The slots on the RMIO boards are
described on page 36 . See the appropriate optional module manual for information
on the cable connections.
Cabling of I/O and fieldbus modules
Cabling of pulse encoder interface module
Fiber optic links
DDCS fiber optic links are provided by RDCO modules for PC tools, master/follower
link, NDIO, NTAC, NAIO, AIMA I/O module adapter and fieldbus adapter modules of
type Nxxx. See the
RDCO User’s Manual [3AFE 64492209 (English)] for the
connections. Observe color coding when installing fiber optic cables. Blue
connectors go to blue terminals, and grey connectors to grey terminals.
When installing multiple modules on the same channel, connect them in a ring.

Note 1: If the encoder is of unisolated
type, ground the encoder cable at the
drive end only. If the encoder is
galvanically isolated from the motor
shaft and the stator frame, ground the
encoder cable shield at the drive and
the encoder end.
Note 2: Twist the pair cable wires.
