Cable Shields
Both ends of the encoder cable’s
screen must
be connected using a 360 degree contact and
not a pig-tail connection.
The 0V must be connected separately from
the screen. Make sure that encoder cables are
specified with one extra wire to carry the 0V.
All serial cables must be terminated in the 15-pin auxiliary connector. For best EMC
performance, clamp the screen of the serial cable where it enters the connector cover.
Do not make a “pig
-
tail” connection from the screen to the plug cover.
The 0V must be
connected separately from the screen.
Make sure that serial cables are specified with one extra wire to carry the 0V.
This applies to RS422/RS485 serial connections as well as RS232.
