Connection between two drive controllers
ƒ Connect cable shield to terminal 89 (direct PE) of the first communication module
and terminal 88 (capacitive PE) of the other communication module. This prevents
the flow of potential equalization currents via the cable shield.
ƒ Connect terminals 71 and 72 between the communication modules via a twisted pair
of cables (e.g. green and yellow).
Direct connection to host
ƒ Connect cable shield to PE on the host side and to terminal 88 on the controller side.
This prevents the flow of potential equalization currents via the cable shield.
