For “long” and/or multidrop connection is also mandatory to
connect the polarization/termination
networks both on the first and last device on the bus
chain: to do so, the pin 5 have to be tied with pin 2
(2 and 3 if the device is a drive) and the pin 9 have to be tied with pin 6 (6 and 7 if the device is a drive).
Shielded cable with twisted pairs (min AWG 22) is also recommended
To enhance EMI noise immunity, when
remote keypad is used with mini-OPD EXP,
it is also recommended to connect the
communication cable shield to ground using
the PE bar of the drive
.
Also some level of noise reduction can be
achieved using a ferrite core (like FairRite
0431178281)
or, better, winding some turns of cable on
toroid (like Vacuumshmelze W516-03).
