What issues should be paid attention to when not using a square frequency converter for a long time

1. Electrolytic capacitors can reduce capacitance and even cause electrolyte overflow, leading to corrosion of printed circuit boards.

2. Cooling fans, if not used for a long time, the lubricating oil of the bearings may dry up, which will affect their service life.

3. For frequency converters that are not used for a long time, charge and discharge them several times every six months with an adjustable power supply.

What measures should be taken when the distance between the electric motor and the frequency converter is far??

When the output line between the frequency converter and the motor is too long, it will have the following effects:

1. The voltage drop of the line increases;

2. The leakage current of the circuit increases;

3. Long line distribution of capacitance and inductance can generate high dv/dt, which can easily damage the motor.

Solution method

1. Suitable for AC output reactors;

2. The frequency converter is used for power amplification in one level.
