Logix/Drive Fault Behavior
These RSLogix 5000 fault actions are configurable from the Axis Properties
dialog box, Fault Actions tab.
Table 56 - Drive Fault Action Definitions
Only selected faults are programmable. In
on page
, the controlling
attribute is given for programmable fault actions.
Figure 68 - RSLogix 5000 Axis Properties - Fault Actions Tab Example
Abnormal noise
Motor tuning limits are set too high.
Run Tune in RSLogix 5000 software again.
Loose parts are present in the motor.
• Remove the loose parts.
• Return motor for repair.
• Replace motor.
Through bolts or coupling is loose.
Tighten bolts.
The bearings are worn.
Return motor for repair.
Mechanical resonance.
Notch filter may be required (refer to Axis Properties dialog, Output
tab in RSLogix 5000 software).
Erratic operation -
Motor locks into position,
runs without control or
with reduced torque.
Motor power phases U and V, U and W, or V and W reversed.
Check and correct motor power wiring.
Sine, Cosine or Rotor leads are reversed in the feedback cable
connector.
Check and correct motor feedback wiring.
Sine, Cosine, Rotor lead sets of resolver feedback are reversed.
Check and correct motor feedback wiring.

Drive Fault Action
Definition
Shutdown
The drive is disabled and the contactor enable relay opens. An uncontrolled stop occurs,
and the motor coasts to a stop.
Disable Drive
The drive is disabled. An uncontrolled stop occurs, and the motor coasts to a stop.
Stop Motion
Logix configuration for velocity loop Kp/Ki is followed. When zero speed is reached or
stopping time is exceeded, the drive is disabled. Stopping time and stopping torque are
configurable parameters in RSLogix 5000 software.
Status Only
Drive continues to operate. Status is provided by the seven-segment status indicator, drive
status indicator, and DPI (if used).
Drive Fault Action/Attribute for
Motor Overtemp fault (E04).
