Possible Cause / Suggested Ac-
tion
At least one phase current is below
the phase loss threshold
Check for blown fuse
Check for loose contacts
Check contact wear
The current in one phase is below
the adjusted threshold.
Check supply side
Check for loose contacts
Check contact wear
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 / pro-
cess 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 / pro-
cess 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 / pro-
cess conditions.
