Setting a Network Time-out The network timeout sets an interval within which the adapter must
communicate with its master. If this time is exceeded, the adapter
determines a loss of network communications has occurred and responds
with the action specified in Parameter 15 - [Comm Flt Action].
By default, the timeout is set to ten (10) seconds. You can increase or
decrease this value. Alternatively, you can set the value to zero (0) so that
the adapter does not detect communication losses.
Set the network timeout in Parameter 11 - [Network Timeout].

ATTENTION: Risk of injury or equipment damage exists.
Parameter 11 - [Network Timeout] lets you determine how
long it will take your adapter to detect network communication
losses. By default, this parameter sets the timeout to ten (10)
seconds. You can set it 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).
