Remedy
If this doesn't help:
U/f operation: Increase the acceleration ramp
•
Reduce the load
•
Replace the power unit
•
Increase the ramp-down time (p1121).
Set the rounding times (p1130, p1136).
Activate the DC link voltage controller (p1240, p1280).
Check the line voltage (p0210).
Check the line phases.
Check the line voltage (p0210).
Check whether the inverter fan is running.
Check whether the ambient temperature is in the permissible range.
Check whether the motor is overloaded.
Reduce the pulse frequency.
Check the rated currents of the motor and Power Module.
Reduce current limit p0640.
When operating with U/f characteristic: Reduce p1341.
Check the inverter's input fuses.
Check the motor feeder cables.
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
Check the power cable connections.
•
Check the motor.
•
Check the current transformer.
•
Check the cables and contacts of the brake connection (a wire might
•
be broken).
Check the supply voltage at the input terminals.
Check the line voltage setting (p0210).
Check whether the fan is running.
•
Check the fan filter elements.
•
Check whether the ambient temperature is in the permissible range.
•
See F30035 and, in addition:
Check the motor load.
•
Check the line phases
•
Check the internal fan and if required replace.
Check the internal fan and if required replace.
Check the unit supply voltage (p0210).
•
Check the dimensioning of the line reactor.
•
Check that the sensor is connected correctly.
A PROFINET controller is attempting to establish a connection with an
incorrect configuration telegram. Check to see whether "Shared Device"
is activated (p8929 = 2).
