Configuring the Adapter
4-Class drives that are daisy-chained to the RJ45 (RS-485) port on
Drive 0. When the adapter is externally mounted in a DSI External
Comms Kit, Drives 0 through 4 are daisy-chained to the RJ45
(RS-485) port on the Comms Kit. Refer to
,
for more information.
2. If a drive is enabled, configure the parameters in the drive to accept
the Logic Command and Reference from the adapter. For example,
set a PowerFlex 40 drive’s parameter P036 - [Start Source] and
parameter P038 - [Speed Reference] both to “5” (Comm Port). When
using the adapter in Multi-Drive mode, each daisy-chained drive
requires that additional parameters be set. See
for these parameters and their settings.

).
By default, when communications are disrupted (for example, a cable is
disconnected) or the controller is in program mode, the drive responds
by faulting if it is using I/O from the network. You can configure a
different response to communication disruptions using Parameter 08 -
[Comm Flt Action] and a different response to a controller in program
mode using Parameter 09 - [Idle Flt Action].
Setting a Fault Action
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 08 - [Comm Flt Action] and 09 - [Idle Flt Action] let you
determine the action of the adapter and connected drive if
communications are disrupted or the controller is in program mode. By
default, these parameters fault the drive. You can set these parameters
so that the drive continues to run. Some ControlNet scanners may
operate differently when a controller is in program mode which could
limit the Idle Fault Action’s operating states. Precautions should be
taken to ensure that the settings of these parameters do not create a risk
of injury or equipment damage. When commissioning the drive, verify
that your system responds correctly to various situations (for example, a
disconnected cable or faulted controller).
