Tips: Variable frequency drive heating problem treatments
The variable frequency drive will generate heat in operation due to internal loss, which the main circuit generates 98% and the control circuit 2%. In summer, the hot weather will raise the temperature of VFD to about 80~90℃. Because of VFD is an electronic device with electron device and electrolytic capacitor. The high temperature can cause components failure, LCD screen no display, and also cause VFD protection action. Therefore, must dissipate heat for VFD in order to extend the life of VFD.
General VFD operating ambient temperature is -10℃~+50℃. In order to ensure reliable operation of the VFD and extend the service life, VFD must perform heat dissipation. In winter, the built-in fan is able to drive the internal heat away. In summer, the temperature can reach 40℃, the built-in fan can only raise the indoor and VFD cabinet temperature. At this time the best way is to use the windows, or drill some φ500mm holes on the wall of the power distribution room near VFD, while ensuring in the cabinet around VFD there is some space, keeping natural ventilation. If this is still not enough, use built-in fan, or install exhaust fan and air flue around the holes to force out the heat. Moreover, the air conditioner can be the final solution for forced cooling.

Practical VFD

We are working on a project and the customer sent a conveyor with the VFD wired up. The old machines we usually use safe torque to ensure safe operation. I don't know if this frequency converter has safe torque, and I also want to know more about this VFD.
