Configuring the Adapter Chapter 3
Setting the Reference
Adjustment
A Reference Adjustment is a percent scaling factor for the Reference from the
network. It can be set from 0.00…200.00% to allow the drive’s Reference to either
match the network Reference (= 100.00%), scale below the network Reference
(< 100.00%), or scale above the network Reference (> 100.00%).
The SMC controllers do not currently use the reference data sent in the IO frame.
No Reference configuration is required. Refer to the applicable SMC user manual
for the latest reference configuration information.
If the adapter is receiving a Reference, set Parameter 39 - [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 events:
• Disrupted I/O communication by using Parameter 23 - [Comm Flt
Action]
• An idle controller by using Parameter 24 - [Idle Flt Action]
ATTENTION: To guard against equipment damage and/or personal injury,
note that changes to adapter Parameter 39 - [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 23 -
[Comm Flt Action] and 24 - [Idle Flt Action] let you determine the action
of the adapter and connected device if I/O communication is disrupted or
the controller is idle. By default, these parameters fault the device. You can
set these parameters so that the device continues to run, however,
precautions should be taken to ensure that the settings of these
parameters do not create a risk of injury or equipment damage. When
commissioning the device, verify that your system responds correctly to
various situations (for example, a disconnected cable or faulted controller).
