Frequency changer

Appears the fault

Analysis reason

Prescription diagnosis and the corresponding

Measure

F0003

The voltage owes

1.Electric power supply breakdown

2.The shock load surpasses the limitation value of stipulation

1.The supply voltage(P0210) must in the frequency changer’s stipulation scope.

2.Whether power source short-time does fall the electricity or has instantaneous stepping down of voltage, whether contacts good.

OFF2

F0004

Frequency changer excessively warm

1.Cooling air blower breakdown

2.Environment hyperpyrexia

1.The cools the air blower must work normal when frequency conversion movement.

2.The modulation pulse frequency must establish for lacks value.

3.The entrance and export cd cools the air flue does not have to stop up

4.The ambient temperature is possibly higher than permissible value of the frequency
