I looked at those inverters also Michael but they are sink mode only which will cause hassles like some others are having (changing chips on 6dof board or making external relay board).
The price seems good but personally i would find a model with source mode to simplify things. Those model will be more expensive though. All of the cheaper models i looked at appeared to be sink mode only.
I just went WJ200's in the end as there is good documentation for them here and they are fairly simple to set up. Compared to other models i looked it with source mode (EG Invertek) they are actually quite a good price.

I can't agree more with Paul on this. Most of these Chinese VFD are poor documented and can be frustrating to set them up correctly.
Thanks Thanos

I don't agree with tronicgr. Not are all the Chinese VFD are of poor document and instruction. You can take a look at the Veichi AC tech VFDs which are of detailed information and user manual.

Perhaps if they had more specific options to work better for PID positioning control and possibly both Sink and Source digital inputs? Looks like all cheap chinese models only do Sink inputs (making it even harder to interface, with leaking currents most of the times back to the computer interface). Is the VFD's you link support Source 24v digital inputs? Thanks Thanos
