Number Cause Solution
 Motor data. Perform commissioning, if necessary.
 Motor connection method (Υ / Δ).
 V/f operation, the assignment of the rated currents of the motor and power unit.
 Line quality.
 The line commutating reactor must be connected properly.
 Power cable connections.
 Power cables for short-circuit or ground fault
 Power cable length
 Line phases
If the fault is still present:
 V/f operation: Increase the up ramp.
 Reduce the load.
 Replace the power unit.
F30002 Power unit: DC-link voltage
overvoltage
 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.
F30003 Power unit: DC-link voltage
undervoltage
 Check the line voltage (p0210).
 Check the line phases.
F30004 Drive overtemperature
 Check whether the drive fan is running.
 Check the ambient temperature.
 Check whether the motor is overloaded.
 Reduce the pulse frequency.
F30005 I2t drive overload
 Check the rated currents of the motor and Power Module.
 Reduce current limit p0640.
 When operating with V/f characteristic: Reduce p1341.
F30011 Line phase failure
 Check the drive's input fuses.
 Check the motor cables.
F30015 Motor cable phase failure
 Check the motor cables.
 Increase the ramp-up or ramp-down time (p1120).
F30021 Ground fault
 Check the power cable connections.
 Check the motor.
 Check the current transducer.
 Check the cables and contacts of the brake connection (a wire might be
broken).
F30022 Power Module: UCE monitoring
 Check the Power Module.
 Replace the Power Module, if necessary.
F30027 Time monitoring for DC link pre-
charging
 Check the supply voltage at the input terminals.
 Check the line voltage setting (p0210).
F30035 Overtemperature, intake air
 Check whether the fan is running.
 Check the fan elements.
 Check the ambient temperature.
F30036 Overtemperature, inside area
F30037 Rectifier overtemperature
 Check whether the fan is running.
 Check the fan elements.
 Check the ambient temperature.
 Check the motor load.
 Check the line phases.
