Troubleshooting Chapter 11
Stall
1. Motor has not reached full speed by the
end of the Stall Enabld Time (Parameter
249) 1. Check for source of stall (for example, excessive
load, or mechanical transmission component
failure).
2. Improper parameter settings
2. Stall Enabled Time (Parameter 249) is set too low
for the application. Check to make sure that FLA
Setting (Parameter 171) is set correctly.
Jam
1. Motor current has exceeded the
programmed jam level
1. Check for the source of the jam (i.e., excessive
load or mechanical transmission component
failure).
2. Improper parameter settings
2. Jam Trip Level (Parameter 253) is set too low for
the application. Check to make sure that FLA Setting
(Parameter 171) is set correctly.
PTC
1. Motor stator windings overheated
1. Check for source of motor overtemperature (for
example, overload, obstructed cooling, high
ambient temperature, excessive starts/hour).
2. Thermistor leads short-circuited or broken 2. Inspect thermistor leads for short-circuit or open
Current Imbalance
1. Imbalance in incoming power 1. Check power system (for example, blown fuse).
2. Motor winding imbalance
2. Repair motor, or if acceptable, raise value of
Current Imbalance Trip Level (Parameter 261), CI
Trip Level
3. Motor idling
3. Raise value of Current Imbalance Trip Level
(Parameter 261) to an acceptable level.
4. Contactor or circuit breaker operation
4. Inspect contactor and circuit breaker for proper
operation.
Nonvolatile Storage
Fault
1. Firmware Downgrade corrupted:
Nonvolatile memory 1.Execute the Clear Command to the operating
Statistics, History Logs, and % TCU
2. Internal product failure 2. Consult the factory.
Hardware Fault
1. Firmware of sensing module is not
compatible with control module firmware
1. Verify firmware revisions of control module and
sensing module
2. Update firmware of control module to v2.0 or
higher
2. Hardware configuration failure
3. Consult the factory.
4. Verify that the Sensing, Control, and
Communication Module are connected properly.
5. Verify that connection pins between sensing
module and control module are not bent.
Configuration Fault
1. Single/Three Phase (Parameter 176) is set
to "Single Phase" and current is being
sensed in phase L3 during motor operation.
1. For three-phase applications, Single/Three Phase
(Parameter 176) should be set to “Three-Phase”; for
single-phase applications, verify that current is
flowing through L1 and L2 only.
2. Operating Mode "Overload (Network)"
does not have an assigned Trip Relay
2. Verify that one of the Output Assignments
(Parameters 202…204) is configured as a "Trip
Relay"
3. Illegal configuration value
3. Review Invalid Configuration Parameter
(Parameter 38) and Invalid Configuration Cause
(Parameter 39) to identify which configuration
parameter is illegal and the reason why.
Remote Trip
1. Contact closure of remote sensor (for
example, vibration switch).
1. Take corrective action to address the issue that
caused the sensor to actuate.
2. Check sensor for proper operation.
3. Check wiring.
Total Starts Warning
1. Starts Counter (Parameter 29) is equal to
or greater than the value set in Total Starts
(Parameter 207) 1. Set Clear Command (Parameter 165) to "Clear
Operating Statistics" to reset Starts Counter
(Parameter 29)
Total Operating
Hours Warning
1. Operating Time (Parameter 28) is equal to
or greater than the value set in Total
Operating Hours (Parameter 208) 1. Clear Command (Parameter 165) to "Clear
Operating Statistics" to reset Operating Time
(Parameter 28)
