Description Possible Causes
„
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.
„
Accessory damaged.
„
Poor connection of the accessory.
„ Problem in the identification of the accessory;
refer to P027.
„
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.
„
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.
„
The function Saves User is blocked.
„
Attempt to copy the parameters from the Flash
Memory Module to the inverter with different
software versions.
