3-4 Configuring the Adapter
2. If Logic Command/Reference is enabled (default), configure the
parameters in the drive to accept the Logic Command and Reference
from the adapter. For example, set
Parameter 90 - [Speed Ref A
Sel] in a PowerFlex 70 or 700 drive to “DPI Port 5” so that the drive
uses the Reference from the adapter. Also, verify that the mask
parameters (for example,
Parameter 276 - [Logic Mask] ) in the
drive are configured to receive the desired logic from the adapter.
3. If you enabled one or more Datalinks (optional), configure
parameters in the drive to determine the source and destination of
data in the Datalink(s). Also, ensure that the PROFIBUS adapter is
the only adapter using the enabled Datalink(s).
4. Reset the adapter. Refer to the Resetting the Adapter section in this
chapter.
The adapter is ready to receive I/O from the master (i.e., scanner). You
must now configure the scanner to recognize and transmit I/O to the
adapter. Refer to
Chapter 4 , Configuring the Profibus Scanner .
By default, when communications are disrupted (for example, a cable is
disconnected) or the master is idle, 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 9 - [Comm Flt Action]
and a different response to an idle scanner using Parameter 10 - [Idle
Flt Action] .
Setting a Fault Action
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 9 - [Comm Flt Action] and 10 - [Idle Flt Action] let you
determine the action of the adapter and connected drive if
communications are disrupted or the scanner is idle. By default, these
parameters fault the drive. You can set these parameters so that the drive
continues to run. Precautions should be taken to ensure that the settings
of these parameters do not create a risk of injury or equipment damage.
