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 implicit I/O.) A ‘1’ enables the I/O and a ‘0’
disables the I/O.

1. Set the bits in Parameter 13 - [DPI I/O Cfg].

Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.

2. If a controller is used to control the drive, set adapter Parameters 25 -

[M-S Input] and 26 - [M-S Output] for Master-Slave Hierarchy.

For details, see

Setting a Master-Slave Hierarchy (Scanner-to-Drive

Communication) on page 3-5

3. 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.

4. 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. See

Chapter 4

for an example.

5. Reset the adapter (see

Resetting the Adapter on page 3-12

The adapter is ready to receive I/O. You must now configure the adapter to
receive I/O from a master or peer device. See

Selecting Master-Slave or

Peer-to-Peer Hierarchy on page 3-5

. If you select a Master-Slave hierarchy,

you must also configure the master to communicate with the adapter. See

Chapter 4
