Building and Installing Cables
Knowledgeable cable routing and careful cable construction improves
system ElectroMagnetic Compatibility (EMC). Refer to Installing Your
Motor on page 9 for suggested feedback and power cable trim lengths,
and for cable shield grounding at the motor frame.
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) 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 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.
