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.
Shor t 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.
Bad motor connection to the drive.
Motor connection is broken.
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 k9 < RPTC < 0k1).
Motor thermistor not installed.
Motor shaft is stuck.
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 k9 < RPTC < 0 k1).
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.
