Configuring the Drive’s Response to a Connection Failure or
Controller Mode Change
The drive contains several parameters that allow you to configure the drive’s
response to communication loss to the controller. From the drive’s
perspective, a communication loss can come in the following two forms.
• The controller closes the connection (for example, the connection is
inhibited).
• A general failure occurs causing the connection to time out.
Parameter 386 [Lgx OutofRunCnfg] configures the drive’s response to the
controller is removed from the Run Mode. Parameter 387 [Lgx Timeout Cnfg]
configures the drive’s response to a general connection failure as detected by
the drive. Parameter 388 [Lgx Closed Cnfg] configures the drive’s response to
the controller closing the connection. All of these parameters configure the
drive’s response to these exception events in the following ways: ignore, alarm,
fault and coast to stop, fault and ramp to stop, fault and stop in current limit.
2. To send additional data from the drive to the controller go to the To Controller tab. Click the To Controller tab.Select the
desired source for the user-defined tag (Output Voltage in this example).
TIP
Use a UserDefinedRealData tag for parameters that
contain floating point data, and use a
UserDefinedIntegerData tag for parameters that contain
integer data.
