Although the VFD drive is a stationary device, the filter capacitors and the cooling fans are power-consuming components. Therefore, the main limiting factors for the lifespan of the VFD drive are the electrolytic capacitors and the fans. A good installation environment and reducing the ambient temperature can extend the lifespan of the VFD drive (typically, for every 10℃ increase in ambient temperature, the lifespan of the VFD drive will be halved).

How long is the lifespan of components?

Electrolytic Capacitor:

The standard lifespan is 5 years due to the natural evaporation of the electrolyte;

Cooling Fan:

The standard lifespan is 2-3 years due to the aging of the lubricating oil.

When will the service life be about to end?

Electrolytic Capacitor:

1. Compared with other machines, the LED lights go out too quickly after power failure;

2. Frequent low-voltage alarms occur;

Cooling Fan:

1. When the fan is running, there is a rubbing sound;

2. When the power is cut off, it stops quickly.
