Cables and Connector Kits
Factory manufactured feedback and power cables are available in
standard cable lengths. They provide environmental sealing and proper
shield termination to an IP66 rating, which exceeds the MP gear motor’s
IP64 rating. For a complete listing of available cables refer to your drive’s
installation manual, contact your nearest Rockwell Automation sales
office, or access the information from the web sites referenced in Related
Documentation on page 30.
Building and Installing Cables
Knowledgeable cable routing and careful cable construction improves
system electromagnetic compatibility (EMC).
To build and install cables, perform the following steps:
1. Keep wire lengths as short as physically possible.
2. Route signal cables (encoder, serial, analog, and brake) away from
motor and power wiring.
3. Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of
parallel run.
4. Ground both ends of the encoder cable shield and twist the signal wire
pairs to prevent electromagnetic interference (EMI) from other
equipment.
ATTENTION
!
High voltage can be present on the shield of a power
cable, if the shield is not grounded.
Ensure there is a connection to ground for any power
cable shield.
Failure to observe these safety procedures could result in
personal injury or damage to equipment.
