AE-T Series High Performance Vector Control User Manual
Part Name Service Life
Fan 3 to 4 Years
Electrolytic capacitor 5 to 6 Years
The user can confirm the replace time according to the running time.
1)
Possible reasons for the damage of cooling fan: bearing wear and blade aging. Distinguish standard: Any
cracks in the fan blade, any abnormal vibration sound during the starting of frequency inverter.
2)
Possible reasons for the damage of filter electrolytic capacitor: poor quality of the input power supply, the
environment temperature is higher, the load change frequently and the electrolyte aging. Distinguish standard:
Any leakage of its liquid, if the safety valve is protruding, electrostatic capacitance and insulation resistance
measurement.
2.7.4
Storage of the frequency inverter
After buying the frequency inverter, users shall pay attention to the temporary and long-term storage as
following:
1)
Store the frequency inverter in the original packaging;
2)
Long-term storage can lead to the degradation of electrolytic capacitors, and must ensure to power on for once
within 2 years. And the power-on time is at least 5 hours. The input voltage must slowly rise to the rating by
using the voltage regulator.
2.8
Warranty Items
1)
Warranty only refers to frequency inverter.
2)
Under normal use, if there is any failure or damage, our company is responsible for the warranty within 12
months. (Leave factory date is subjected to the S/N on the frequency inverter nameplate or the contract). When
over 12 months, reasonable maintenance fee will be charged;
3)
During 12 months, if the following situation happens, certain maintenance fee will be charged;
a, The users don’t follow the manual stated makes the frequency inverter damaged;
b, The damage caused by fire, flood and abnormal voltage;
c.
The damage caused by using the frequency inverter for abnormal functions;
d.
The relevant service fee is calculated according to the manufacturer’s standard, if there is contract, then it
carries out subject to the contract.

Selection Guide of braking component
Table 2-5 is the recommended value of braking resistor, users can select the different resistance value and power
according to the actual situation,(but the resistance value must not be less than the recommended value in the
table, and the power can be bigger.) The selection of braking resistance need to be confirmed according to the
power that the motor generated in the practical application systems, and is relevant to the system inertia,
deceleration time, the energy of the potential energy load, needs customers to choose according to actual
situation. The greater the inertia the shorter deceleration time is needed and more frequently braking, so the
braking resistor needs the one with bigger power but smaller resistance value.
2.9.1
Selection of braking resistance value
When braking, almost all the renewable energy of motor is consumed on the braking resistor.
