ATTENTION: Risk of injury or equipment damage exists. Parameter 25 - [DSI
Loss Action]
lets you determine the action of the adapter when DSI
communication with the drive has been lost. By default, this parameter maintains
the Logic Status and Feedback word values sent to the controller at the timeDSI
communication was lost (that is, hold last state). Alternatively, you can set this
parameter so that the Logic Status and Feedback word values are zeroed after a
DSI communication loss. Whether the drive faults or takes a different action is
determined by the setting of the following drive parameter:

Precautions should be taken to ensure that the setting of adapter Parameter 25
and drive parameter A105, C304 or C105 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 faulty drive DSI cable or
excessive electrical noise interference).
