No. Trip Possible ccause Remedy aactions
E10 Trips at the current transformers Current transformer is defect Replace current transfomer
E11 Trip of calculator Electromagnetic fields, Check of possible external
frequency inverter defect disturbances,
contact the customer service
E12 External fault An external fault is send via a Check the reason of the trip
digital input of the inverter and solve the problem
E13 Trip by restart lock Switch-on of mains voltage at The corresponding terminal must
active lock or mains failure at not be interconnected before
active lock switching on mains,
check mains voltage supply
E14 Earth fault on the motor terminals Earth fault Remove earth fault and check
the motor
E15 Mains overvoltage Mains overvoltage is higher than the Check the mains voltage
nominal voltage of the inverter
E16 Short mains failures Are there mains voltage dips in the Check the input voltage
range > 15ms ?
E21 Overtemperature in power part Inverter overload, Check the motor current,
ambient temperature too high check ambient temperature,
check fans
E23 Communication error Trip between CPU and interface Replace control printed circuit
E24 Phase failure A phase of the mains voltage fails Check mains voltage
or the mains voltage is switched off
during deceleration
E30 IGBT failure Is the motor bigger than the Select a frequency inverter of
frequency inverter ? higher performance.
Was there a sudden load increase Avoid overloads.
or is the motor stalling ? Use inverter and motor of
higher performance.
Is there a short-circuit of the motor Check motor and motor cables
terminals U, V, W ? for short-circuit.
E35 Motor thermistor activated Motor overload, Check load of the motor,
Is the self-ventilation of the motor - check built-in distances
especially at low speed - to less,
built-in distances to short
