Installation/Wiring Chapter 1
Wiring terminations on the master controller will vary depending on the
master controller used and “TxRxD+” and “TxRxD-” are shown for
illustration purposes only. Refer to the master controller’s user manual for
network terminations. Note that there is no standard for the “+” and “-” wires,
and consequently Modbus device manufacturers interpret them differently. If
you have problems with initially establishing communications, try swapping
the two network wires at the master controller.
On Drive Connections
PowerFlex 400 Frame D, E, F, G and H drives are equipped with two RS485
(DSI) ports. One is accessible via an access door when the cover is on and one is
only accessible with the cover off. When one of these ports has a Rockwell DSI
device connected, the second port cannot be used.
