Quick Reference of Parameters, Alarms and Faults
Description
It occurs when there is an attempt to
copy the SoftPLC application protected
against copies.
Undervoltage fault on the intermediate
circuit.
Overvoltage fault on the intermediate
circuit.
Stator resistance setting fault P409.
Overtemperature fault measured on the
temperature sensor of the power pack.
Overcurrent or short-circuit on the
output, DC link or braking resistor.

Possible Causes
„
Attempt to copy WLP application protected
against copies ("never permit copies").
„ Attempt to copy WLP from a copy protected
against copies ("no permission to copy from
a copy")
„
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 (in P004):
Ud < 200 Vdc in 200 / 240 Vac.
„ 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
(in P004):
Ud > 410 Vdc in 200 / 240 Vac.
„
Load inertia is too high or deceleration ramp
is too fast.
„
P151 setting is too high.
„
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.
„ High temperature at IGBTs (P030 > 120 °C).
„ 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.
„ IGBTs module in short-circuit or damaged.
„ Start with too short acceleration ramp.
„
Start with motor spinning without the Flying
Start function.
„ P156 setting is too low in relation to the motor
operating current.
„
Overload on the motor shaft.
