Parameter 15 - [Comm Flt Action] lets you determine the
action of the adapter and connected drive if communications are
disrupted. By default, this parameter faults the drive. You can set
this parameter so that the drive continues to run. Precautions
should be taken to ensure 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).

ATTENTION: Risk of injury or equipment damage exists.
Parameter 11 - [Network Timeout] lets you determine how
long it will take the adapter to detect network communication
losses. By default, this parameter sets the timeout to ten seconds.
It can be set so that the duration is shorter, longer, or disabled.
Take precautions to ensure that the setting 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).
!
ATTENTION: Risk of injury or equipment damage exists. DPI
or SCANport host products must not be directly connected via
1202 cables. Unpredictable behavior due to timing and other
internal procedures can result if two or more hosts are connected
in this manner.

ATTENTION: Risk of injury or equipment damage exists.
When a system is configured for the first time, there may be
unintended or incorrect machine motion. Disconnect the motor
from the machine or process during initial system testing.
