Cause
The power unit has detected overvoltage
in the DC link.
Motor regenerates too much energy.
•
Device connection voltage too high.
•
Line phase interrupted.
•
The power unit has detected an undervolt-
age condition in the DC link.
Line supply failure
•
Line supply voltage below the permis-
•
sible value.
Line supply infeed failed or interrupted.
•
Line phase interrupted.
•
The temperature of the power unit heat
sink has exceeded the permissible limit
value.
Insufficient cooling, fan failure.
•
Overload.
•
Surrounding temperature too high.
•
Pulse frequency too high.
•
The power unit was overloaded.
The permissible rated power unit cur-
•
rent was exceeded for an inadmissibly
long time.
The permissible load duty cycle was
•
not maintained.
At the power unit, the DC link voltage rip-
ple has exceeded the permissible limit
value.
Possible causes:
A line phase has failed.
•
The 3 line phases are inadmissibly
•
unsymmetrical.
The fuse of a phase of a main circuit
•
has ruptured.
A motor phase has failed.
•
Remedy
Increase the ramp-down time.
•
Activate the DC link voltage controller.
•
Use a braking resistor.
•
Increase the current limit of the infeed or
•
use a larger module.
Check the device supply voltage.
•
Check the line supply phases.
•
Check the line supply voltage
•
Check the line supply infeed and observe
•
the fault messages relating to it (if there
are any)
Check the line supply phases.
•
Check the line supply voltage setting.
•
Check whether the fan is running.
•
Check the fan elements.
•
Check whether the surrounding tempera-
•
ture is in the permissible range.
Check the motor load.
•
Reduce the pulse frequency if this is high-
•
er than the rated pulse frequency.
Reduce the continuous load.
•
Adapt the load duty cycle.
•
Check the motor and power unit rated
•
currents.
Check the main circuit fuses.
•
Check whether a single-phase load is
•
distorting the line voltages.
Check the motor feeder cables.
