The VFD/spindle bundle I purchased was from Amazon. It contained a 110V VFD which upconverts to run a spindle at 220V (at least, I'm fairly sure thats what I bought). The specific VFD model can be seen below (HY02D211B):
There was a video posted to Amazon which documented the settings required for this VFD as well as the process for programming:
- PD013 = 8 (factory reset)
- PD005 = 400 (max operating frequency)
- PD004 = 400 (base operating frequency)
- PD002 = 1 (set potentiometer control)
- PD070 = 1 (set analog input)
- PD072 = 400 (set high analog frequency)
This alternate video also describes the programming process well, but for a different model VFD (so the parameters do not match exactly).
In order to program the device, you must first connect the VFD to power without wiring the spindle (not sure the spindle not being there really matters, but I tried to follow the video steps). This presented the first hurdle, as a complete wiring diagram was not included in the manual. A little online research and a lucky guess provided the solution. First remove the wiring access panels on the VFD:
Then run a 12/3 wire (in this case, 12/3 SJOOW) and connect as follows:
- Black (HOT) to R
- Neutral to T
- Ground to Ground
After reassembly and powering on the device, the programming can be completed using the following steps:
- PRGM (to start the programming sequence)
Then for each parameter, perform these steps:
- Up/Down arrows to select PD00x parameter
- SET
- Up/Down arrows to select value, SHIFT can be used to move the cursor
- SET (to accept the value)
Finally, to complete the programming, press:
- STOP (big red button to complete the programming sequence)
After completing this process, the next step is wiring the spindle to the VFD, to be covered in a future post...
