Regular maintenance
According to the use environment, the user can conduct a regular routine inspection of FC100P
within 3-6 months to eliminate potential failures and ensure long-term high-performance and stable
operation of the equipment.
The inspection contents are:
•
control terminal screw is not loose, if it is loose, tighten it with a screw batch with appropriate
torque and size ;
•
The power terminals are firmly in contact, and there is no trace of overheating at the copper
bar or cable connection;
•
Whether the power cables and control cables are damaged, especially if there is no cut on
the skin in contact with the metal surface;
•
The wire lug insulation bandages of power cables and control signal wires do not fall off or
break;
•
It is best to use a vacuum cleaner to clean the dust on the circuit board and air duct
comprehensively.
Notice:
1. The inverter has passed the withstand voltage test before leaving the factory, and the user
does not need to carry out the withstand voltage test, otherwise the inverter will be damaged
if the test is not done properly.
2. When conducting an insulation test on the motor, the U/V/W terminals of the inverter must be
disconnected, and the motor is tested separately, otherwise the inverter will be damaged.
3. Inverters stored for a long time must undergo a power-on test within 2 years. Use a voltage
regulator to slowly increase the input voltage of the inverter to the rated value, and power on
for at least 5 hours.
Replacement of wearing parts
Vulnerable parts of the inverter mainly include cooling fan and filter electrolytic capacitor. Their
service life is closely related to the environment of use and maintenance status. Users can set the
replacement period according to the running time.
Consumables
cooling fan
Filter electrolytic capacitor
life time
60,000 hours
50,000 hours
possible cause
of damage
Bearing wear, blade aging
The ambient temperature is high, frequent
load jumps cause the pulsating current to
increase, and the electrolyte is aging
Criterion
When the inverter is powered off, check
whether there are cracks in the fan blades,
etc.; when the drive is powered on, check
whether the fan is running normally,
whether there is abnormal vibration, noise,
etc.
Whether the frequency converter often has
overcurrent, overvoltage and other faults
when it is running under load; whether
there is liquid leakage, whether the safety
valve has protruded, the measurement of
electrostatic capacitance, and the
measurement of insulation resistance
Disposal
When scrapping , please note:
•
The electrolytic capacitor inside the inverter may explode if burned.
•
Toxic gases are produced when plastic parts are incinerated.
•
Please dispose of it as industrial waste.
