Pulse encoder module cabling
Fiber-optic link
A DDCS fiber-optic link is provided via the RDCO option module for PC tools,
master/follower link and the AIMA-01 I/O module adapter. See
RDCO-01/02/03/04
DDCS communication option modules
(page 141) for the connections. Observe color
codes when you install fiber-optic cables. Blue connectors go to blue terminals, and
gray connectors to gray terminals.
When installing multiple modules on the same channel, connect them in a ring.
Warning sticker
There are warning stickers in different languages inside the packing box of the drive.
Attach a warning sticker in the local language onto the cover of the drive module.

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.
