Connecting the Kinetix 6000M System Chapter 5
The Sercos Fiber-optic Ring The sercos fiber-optic ring is connected by using the sercos receive (RX) and
transmit (TX) connectors. Refer to
Sercos Fiber-optic Connectors on page 41
for details. Refer to the documentation supplied with your Logix sercos interface
module or PCI card for connector locations.
Plastic cable is available in lengths up to 32 m (105.0 ft). Glass cable is available in
lengths between 50 m (164.2 ft) and 200 m (656.7 ft).
Connect the cable from transmit on the Logix module to receive on the first
IPIM module, then transmit to receive (module to module), and from transmit
on the last module back to receive on the Logix module.
The IPIM module has fiber-optic cable connectors positioned identical to the
Kinetix 6000 (2094-BM
xx-S) drives, the IPIM module uses the same fiber-optic
cable lengths as the drive modules.
In the following example ( Figure 25 ), all of the drive modules and the IPIM
module are on the same sercos ring. The ring begins and ends at the 1756-M16SE
sercos module. IDM units connected to the IPIM module (not shown for
simplicity) are also part of this sercos ring.

ATTENTION: To avoid damage to the sercos RX and TX connectors use only
finger-tight torque when attaching the fiber-optic cables. Do not use a wrench
or any other mechanical assistance. For more information, refer to Fiber-optic
Cable Installation and Handling Instructions, publication
2090-IN010 .
IMPORTANT Clean the fiber-optic cable connectors prior to installation. Dust in the
connectors can reduce signal strength. For more information, refer to Fiber-
optic Cable Installation and Handling Instructions, publication
2090-IN010 .
