Pulse encoder module cabling
Fibre optic link
A DDCS fibre optic link is provided via the RDCO optional module for PC tools,
master/follower link, NDIO, NTAC, NAIO, AIMA I/O module adapter and fieldbus
adapter modules of type Nxxx. See
RDCO User’s Manual [3AFE64492209
(English)] for the connections.
When installing multiple modules on the same channel, connect them in a ring.
Warning sticker

Clamp as close to the terminals as
possible.
As short as
possible
Note1: 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.
Note 3: The grounding wire of the outer
shield of the cable can alternatively be
connected to the SHLD terminal of the
RTAC module.
