Quick Parameter Reference, Faults and Alarms
Description Possible Causes
Surrounding air temperature too high (>50 °C (122 °F))
and excessive output current.
Defective internal fan (if installed).
Surrounding air temperature ≤ -30 °C (-22 °F).
Broken AI1 cable;
Bad contact at the signal connection to the terminal strip
Broken AI2 cable;
Bad contact at the signal connection to the terminal strip
Broken AI3 cable;
Bad contact at the signal connection to the terminal strip
Broken AI4 cable;
Bad contact at the signal connection to the terminal strip
Maximum number of operating hours for the heatsink fan
has been reached.
Dust on fan blades and bearings.
Defective fan.
It is necessary to set date and time at parameters P0194
to P0199.
Keypad battery is discharged, defective, or not installed.
Defect in the inverter internal circuitry.
Surrounding air temperature too high.
Operation with frequencies < 10 Hz under overload.
Pre-charge contactor defect
High ambient temperature (>45°C) and high output
current.
Blocked or defective fan.
Fins of the book heatsink too dirty, impairing the air flow.
