The inverter turns off its output when the output current of
the inverter flows more than the rated level (150% for 1
minute).
The inverter turns off its output if the output current of the
inverter flows at 150% of the inverter rated current for more
than the current limit time (1 min).
The load is greater than the
motor’s rated capacity.
Ensure that the motor and inverter have appropriate capacity ratings.
There is a fault with the output
module (IGBT).
Refer to 3.1.4 Checking the Input/Output Modules on page38 and
check a fault with the output module(IGBT)
Do not operate the inverter. Contact the retailer or the LSIS customer
service center.
The load is greater than the
rated motor capacity.
Replace the motor and inverter with models that have increased
capacity.
The torque boost level is too
high.
Reduce the torque boost level.
Acc/Dec time is too short,
compared to load inertia (GD2).
Displayed when the tempertature of the inverter heat sink
exceeds the specified value.
There is a problem with the
cooling system.
Determine if a foreign object is obstructing the air inlet, outlet, or vent.
The inverter cooling fan has
been operated for an extended
period.
Replace the cooling fan (Refer to 3.1.3 Replacement of the cooling
fan)
The ambient temperature is too
high.
Keep the ambient temperature below 50℃.
