Setting the I/O
Configuration
The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. (Datalinks allow you to read/write directly to
parameters in the drive using Discrete I/O.) A ‘1’ enables the I/O and a ‘0’
disables the I/O.
1. Set the bits in Parameter 12 - [DPI I/O Config].
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
2. If Logic Command/Reference is enabled, 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 ‘22’ (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. See the documentation for your drive for
details.
3. If you enabled one or more Datalinks, configure parameters in the drive
to determine the source and destination of data in the Datalinks.
When using Datalinks, up to 8 drive [Data In xx] parameters
(300…307) and/or up to 8 [Data Out xx] parameters (310…317) must
be assigned to point to the appropriate drive parameters for your
application. Also, ensure that the Remote I/O adapter is the only adapter
using the enabled Datalinks. See
Chapter 4 , Using Discrete and Block
Transfer I/O for an example.
4. Reset the adapter (see Resetting the Adapter on page 3-8 ).
The adapter is ready to receive I/O.
