Rockwell Automation 22-COMM-B PowerFlex BACnet MS/TP Adapter - Manual (Page 27)

Installing the Adapter 2-11
The following steps in this section assume that the drive will receive the
Logic Command and Reference from the BACnet MS/TP network.
1. Using drive Parameter P038 - [Speed Reference], set the drive
speed Reference to “5” (Comm Port).
2. Verify that drive Parameter P036 - [Start Source] is reporting that the
source of the Reference to the drive is “5” (Comm Port). This ensures
that any Reference commanded from the network can be monitored by
using drive Parameter d002 - [Commanded Freq]. If a problem
occurs, this verification step provides the diagnostic capability to
determine whether the drive/adapter or the network is the cause.
1. Remove power from the drive.
2. Use static control precautions.
3. Connect one end of a shielded, twisted wire pair to the network.
4. Route the other end of the twisted wire pair through the bottom of the
drive (see Figure 2.5 ). Connect the twisted wire pair and its shield to
the 3-pin linear plug (provided with the adapter). See Figure 2.9 for
terminal designations and typical terminal connections.

ATTENTION: Risk of injury or death exists. The PowerFlex drive
may contain high voltages that can cause injury or death. Remove
power from the drive, and then verify power has been discharged
before installing or removing an adapter.
