Configuring the Adapter
See
for details to set the node address.
The I/O configuration determines the number of drives that will be
represented on the network as one node by the adapter. If the Mode
Jumper J2 is set to the “1x” (Single mode) default position, only one
drive is represented by the adapter and Parameter 11 - [DSI I/O Cfg]
has no effect. If the Mode Jumper J2 is set to the “5x” (Multi-Drive)
position, up to five drives can be represented as one node by the adapter.
1. Set the value in Parameter 11 - [DSI I/O Cfg].
Figure 3.2 Example DSI I/O Cfg HIM Screen
When the adapter is internally mounted in a PowerFlex 40, PowerFlex
40P or PowerFlex 400 drive, this drive is always Drive 0. Drives 1
through 4 are PowerFlex 4-Class drives that are daisy-chained to the
RJ45 (RS-485) port on Drive 0. When the adapter is remotely
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. Configure the parameters in the drive to accept the Logic Command
and Reference from the adapter. In a PowerFlex 40 drive, for
example, set 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.
3. Reset the adapter. See
Resetting the Adapter on page 3-8
The adapter is ready to receive I/O from the master (that is, scanner).
You must now configure the scanner to recognize and transmit I/O to the
adapter. See
Configuring the Profibus Scanner
