For 842E-CM encoders, shutdown is currently the only selectable
exception behavior in the Logix Designer application from the Axis
Properties dialog box, in the Actions category.
Table 5 - Exception Action Definition
Only selected encoder exceptions are configurable. In the fault behavior
tables, the controlling attribute is given for programmable fault actions.
See the Logix Designer Axis Properties screen, Actions category.

Shutdown When the exception occurs, the encoder brings the motor to a stop by using
the stopping action defined by the encoder (as in Stop encoder) and the
power module is disabled. An explicit Shutdown Reset is required to restore
the encoder to operation
