Possible Cause / Suggested Action
The rotor is locked. Load too heavy for motor.
Thermal model reached warning level. If overload condition remains
a trip soon follows.
Check motor load condition
Check for mechanical problems
PTC element indicated that motor temperature is too high
Check motor environment and load conditions
See codes 83/84
See codes 80...82
Motor current is below user-defined threshold e.g. motor running
idle, dry running pump, conveyer belt broken ...
Check motor load and motor / process conditions. Wait until
cooling time is over.
Motor current is below user-defined threshold e.g. motor running
idle, dry running pump, conveyer belt broken ...
Check motor load and motor / process conditions
Motor current above threshold caused e.g. by jammed equipment
Check process conditions (remove blocking cause). Wait until
cooling time is over.
Motor current above user-defined threshold.
Check motor load and motor / process conditions.
Connection between one or more phases and ground
Check wiring / motor (isolation problem)
See above
Hardware fault detected, more details see under no. 128...140;
On LCD panel: -> maintenance/service -> Diagnosis -> Error history
Replace UMC
Open/close time of actuator exceeded because of tight valve or
other mechanical reasons.
Check runtime parameter and limit and torque switch wiring
Communication cable not connected. Cable break or IO module
hardware error.
An unrecoverable error was detected while processing the custom
application (e.g. checksum error)
The version of application editor and UMC are not compatible
A self-test error was detected in an IO module.
Check the LEDs on the module
Replace the module
The digital input of an IO module has created a trip/warning.
Reason depends on what you have connected to the input.
Note: If the "AuxWarnFault" function block is used in a different way
than in the predefined applications also other inputs than the
DX1xx can be the fault source.
A multifunction input of the UMC has triggered a trip.
The reason depends on what you have connected to the input.
