ATTENTION: Risk of injury or equipment damage exists. Parameter 10 -
[Comm Flt Action] lets you determine the action of the adapter and connected
drive if I/O communication is disrupted. By default, this parameter faults the
drive. You can set this parameter so that the drive continues to run, however,
precautions should be taken to verify that the setting of this parameter does 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).
