Overload on the IGBTs IGBTs (3 s in 1.5xInom).
Note:
This failure may be disabled, by setting
P0343 = 0 or 1.
F0051 Overtemperature fault measured on the
IGBTs overtemperature temperature sensor of the power pack.
F0070 Overcurrent or short- circuit on the
Overcurrent/Short- circuit output, DC link or braking resistor.
F0072 Motor overload fault (60 s in 1.5xInom)
Motor overload
F0074 Ground overcurrent fault.
Ground fault Note:
This failure may be disabled, by setting
P0343 = 0 or 2.
F0076 This fault indicates the motor presents
Output Phase Current phase loss, imbalanced phase current or

Possible Causes
Plug-In module is damaged.
Plug-In module is not properly connected.
Problem in the identification of the Plug-In module; refer to
P0027 for further information.
Stator resistance value in P0409 does not comply with the
inverter power.
Motor connection error; turn off the power supply and check the
motor terminal box and the connections with the motor terminals.
Motor power too low or too high in relation to the inverter.
Inverter output overcurrent (>2xInom).
High ambient temperature around the inverter (>50 °C (>122 °F))
and high output current.
Blocked or defective fan.
Heatsink is too dirty, preventing the air flow.
Short- circuit between two motor phases.
Short- circuit of the rheostatic braking resistor connecting
cables.
IGBTs module in short- circuit or damaged.
Start with too short acceleration ramp.
Start with motor spinning without the flying-start function.
P0156, P0157 and P0158 setting is too low in relation to the
motor operating current.
Overload on the motor shaft.
Short-circuit to the ground in one or more output phases.
Motor cable capacitance too high, causing current peaks in
the output.
Motor wiring or connection error.
Loss of motor connection with the drive or broken wire.
Overload on the motor shaft.
Load cycle is too high (high number of starts and stops per
minute).
High ambient temperature around the motor.
Poor contact or short circuit (3.9 kΩ < R
Motor thermistor not installed.
Motor shaft is stuck.
Electric noise.
Inverter firmware fault.
Poor contact in the connection between the main control and
the power pack.
Hardware not compatible with the firmware version.
Defect on the internal circuits of the inverter.
Wiring on DI1 to DI8 inputs are open or have poor contact.
Hardware identification fault; compare P0295 and P0296 to
the inverter identification label.
Inverter internal circuits fault.
Check network installation, broken cable or fault/poor contact
on the connections with the network, grounding.
Ensure the master always sends telegrams to the equipment
in a time shorter than the setting in P0314.
Disable this function in P0314.
Check if the communication interface with the HMI is properly
configured in parameter P0312.
HMI cable disconnected.
