Logix Controller/IDM Unit Fault Behavior
These RSLogix 5000 fault actions are configurable from the Axis Properties
dialog box, Fault Actions tab.
Table 21 - Fault Action Definitions
Only selected faults are programmable. Table 22 indicates which faults have a
programmable RSLogix Fault Action. Faults that do not have a programmable
fault action will have the Shutdown action described in Ta b le 21
.

Fault Action Definition
Shutdown Axis is disabled as defined in Table 22. In addition, the axis in Logix enters the Shutdown
state, which disables any axes that are using this axis as a camming or gearing master. The
AxisHomedStatus tag for the faulted axis is cleared. Shutdown is the most severe action to a
fault and it is usually reserved for faults that could endanger the machine or operator if
power is not removed as quickly as possible.
Disable Drive The axis is disabled as defined in the Table 22
.
Stop Motion The axis decelerates at the maximum deceleration rate (set in RSLogix 5000 software>Axis
Properties>Dynamics tab). Once the axis has come to a stop, the servo loops remain enabled
but no further motion can be generated until the fault is reset. This is the gentlest stopping
mechanism in response to a fault. It is usually used for less severe faults.
Status Only System continues to operate. Status is displayed on the IPIM module.
