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 [3AFE 64492209
(English)] for the connections. Observe colour coding when installing fibre 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.
Installation of user's own relays
A motor thermistor relay can be installed to a rail in the pedestal (frame size R7) or
on the lead-through plate (frame size R8), or to a DIN rail in the enclosure extension.
Installation of brake resistors

connection diagram
Parameter settings
To enable dynamic braking, certain drive parameters must be adjusted. For further
information, refer to the Firmware Manual.
Installation
Clamp as close to the terminals 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.
