Kundeanmeldelser for VEVOR VFD 2,2 kW 10 A 3 hk variabel frekvensomformer for 3-faset motorhastighetskontroll

Obtained this VFD to operate a 3hp Delta Unisaw with a 3phase 220V motor. The VFD does not provide any "enclosure" for connection of input power or 3-phase output. So I utilized a general purpose enclosure underneath the VFD to connect the conduit and bring the individual conductors to the VFD. That enclosure needs to have ventilation to provide for the fans built into the bottom of the VFD. How the VFD is constructed pretty much requires that the VFD be mounted in a vertical orientation, in order for the fans to effectively cool the heatsink. No mounting position requirements mentioned in the instructions. The terminals for connection to the VFD are a screw with a washer under the head. The best connection is a 6mm / 1/4" wide forked spade, although a solid conductor up to 10 guage can fit. If using a stranded conductor, it would be best to solder-dip the conductor for safe and effective connection. The screws for connection are quite short, only screwing out about 4 turns before totally unscrewing, and theres no "stop" to prevent one from totally removing the connection screw. Then, the design of the case is such that it is very nearly impossible to get a connection screw in once removed. Once those installation challenges are overcome, the VFD works great. Press start, and it takes 10 seconds for the motor to gradually come up to speed. A turn knob allows adjustment of speed. In my application, a shop table saw, it would be nice to have big, tactile buttons to push for start/stop, especially the stop. The front panel of the VFD has a membrane keypad, that one must look at and very carefully touch the needed button with a fingertip to get start or stop. There is the provision built into the VFD to connect larger pushbutton switches and relays, to implement more shop-safe start/stop start. Overall it accomplished what I needed, and once I adjust to the slight inconvenience of needing to be more diliberate and careful in turning on and off, will serve very well.
