3. Set Parameter 30 - [Peer A Input] to select the destination of the data
that is input to the drive as Peer A.
Important: When receiving a 32-bit Reference or 32-bit Datalink, only
Peer A Input will be available. Peer B Input cannot be used.
4. If desired, set Parameter 31 - [Peer B Input] to select the destination
of the data to input to the drive as Peer B.
5. If the adapter receives a Logic Command, set the bits in Parameter 32 -
[Peer Cmd Mask] that the drive should use.
The bit definitions for the Logic Command word will depend on the
drive to which the adapter is connected. See
or the drive
documentation.
Important: If the adapter receives a Logic Command from both a
Master device and a Peer device, each command bit must
have only one source. The source of command bits set to
‘0’ will be the Master device. The source of command bits
set to ‘1’ will be the Peer device.
6. Reset the adapter (see
Resetting the Adapter on page 3-12
) so that
changes to Parameter 32 - [Peer Cmd Mask] take effect.
7. If the adapter is receiving a Reference, it can be scaled using
Parameter 33 - [Peer Ref Adjust] to the desired scaling factor
between 0.00…199.99%.
!
ATTENTION: To guard against equipment damage and/or
personal injury, note that changes to adapter Parameter 33 -
[Peer Ref Adjust] take effect immediately. A drive receiving its
Reference from peer I/O will receive the newly scaled Reference,
resulting in a change of speed.
