(3) Cable stresses
(1) The way of clamping the cable must be fully
considered so that flexing stress and cable's own
weight stress are not applied to the cable
connection.
(2) In any application where the motor moves, do not
subject the cable to excessive stress.
(3) Avoid any probability that the cable sheath might
be cut by sharp chips, rubbed by a machine corner
or trampled over by workers or vehicles.
(4) The reference value of dedicated encoder cable
flexing life is shown on the right.
When mounting the encoder on a machine where
the motor will move, the flexing radius should be as
large as possible.
