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 (>2xI
„
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 (3k9 < RPTC < 0k1).
„
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.
„
Blank memory on plug-in module (1st power-up).
„
Data backup fault during power-down.
„
Hardware identification fault; compare P0295 and
P0296 to the inverter identification label.
„
Inverter internal pulse feedback circuit fault.
