Configuring the Adapter 3-5

The adapter is ready to receive I/O from the master (that is, scanner). You
must now configure the scanner to recognize and transmit I/O to the adapter.
See
Chapter 4 , Configuring the I/O .
Setting the Reference
Adjustment A Reference Adjustment is a percent scaling factor for the Reference from
the network. It can be set between 0.00…200.00% to allow the drive’s
Reference to either match the network Reference (equal to 100.00%), scale
below the network Reference (less than 100.00%), or scale above the
network Reference (more than 100.00%).
If the adapter is receiving a Reference, set Parameter 27 - [Ref Adjust] to
the desired scaling factor.
The adjustment takes effect as soon as it is entered.
Setting a Fault Action By default, when I/O communication is disrupted (for example, a cable is
disconnected) or the controller is idle (in program mode or faulted), the
drive responds by faulting if it is using I/O from the network. You can
configure a different response to these faults:
• Disrupted I/O communication by using Parameter 10 - [Comm Flt
Action]
• An idle controller by using Parameter 11 - [Idle Flt Action]
!
ATTENTION: To guard against equipment damage and/or
personal injury, note that changes to adapter Parameter 27 - [Ref
Adjust] take effect immediately. A drive receiving its Reference
from the adapter will receive the newly scaled Reference,
resulting in a change of speed.

ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
I/O communication is disrupted or the controller is idle. By
default, these parameters fault the drive. You can set these
parameters so that the drive continues to run, however,
precautions should be taken to verify that the settings of these
parameters do not create a risk of injury or equipment damage.
When commissioning the drive, verify that your system responds
correctly to various situations (for example, a disconnected cable
or faulted controller).
