Possible Causes
Wrong voltage supply; check if the data on the inverter label
comply with the power supply and parameter P296.
Supply voltage too low, producing voltage on the DC Link
below the minimum value (Level F021) according to
1.2 on page
16.
Phase fault in the input.
Fault in the pre-charge circuit.
Wrong voltage supply; check if the data on the inverter label
comply with the power supply and parameter P296.
Supply voltage is too high, producing voltage on the DC
Link above the maximum value (Level F022) according to
Table 1.2 on page
16.
Load inertia is too high or deceleration ramp is too fast.
P151 setting is too high.
Auxiliary Processor damaged.
Problem in the identification of the Auxiliary Processor; refer
to P027.
Application's HMIR or bluetooth accessory damaged.
Poor connection of the Application's HMIR or bluetooth
accessory.
Problem in the identification of the Application's HMIR or
bluetooth accessory; refer to P028.
Stator resistance value in P409 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.
Settings of P156 is too low for the used motor.
Overload on the motor shaft.
High ambient temperature around the inverter and high
output current. For further information, refer to of the
user's manual available for download on the website:
www.weg.net.
Heatsink is too dirty, preventing the air flow.
Inverter installed in a position out of the airflow of the
evaporative cooler blades.
High ambient temperature around the inverter and high
output current. For further information, refer to of the
user's manual available for download on the website:
www.weg.net.
Heatsink is too dirty, preventing the air flow.
Inverter installed in a position out of the airflow of the
evaporative cooler blades.
Short-circuit between two motor phases.
IGBTs module in short-circuit or damaged.
Start with too short acceleration ramp.
Start with motor spinning without the Flying Start function.
P156, P157 or P158 setting is too low in relation to the
motor operating current.
Overload on the motor shaft.
Electric noise.
Inverter firmware fault.
Attempt to save (P204 = 9) more than 32 parameters
(with values different from the factory default) on the User
parameter table.
