Underload Power 34 Load side mechanics The motor load is too low. Check the load e.g. if a pump is running
dry or a conveyer load is broken.
Overload Power 35 Load side mechanics The motor load is too high. Check if the load is blocked or tight.
Voltage Out of Spec 36 Load side The supply voltage is too low or too high. Check the motor supply.
THD Warning 37 Supply side The harmonics on the supply side are too high. Check your network.
Num Starts Overrun 43 Application The motor was started too frequent.
Just One Start Left 44 Application The motor was started too frequent.
Cooling time running 45 Process, Load side Motor was tripped due to thermal overload. Restart is possible
after cooling time is over
Parameter out of range 54 Electronics, Configuration Someone tried to write a parameter which is outside the
specifications
Check the parameter number that is causing the problem and
change the value.
When writing parameters from within a PLC check your program.

Expected feedback from a contactor is missing after checkback
time was over.
Check wiring of auxiliary contact to the correct UMC input.
Check contactor

Supply side,
Load side
No motor current after motor was switched on and checkback time
was over. Or motor current falls below 20% while motor is running.
Check supply side
Check that I
