SIPUN SPVF-2.2G-S2 Variable Frequency Drive

Post by leadgtr7 » Fri Jan 28, 2022 9:11 am

Does anyone know if this VFD is supported?

https://www.amazon.com/dp/B0972MCVV5/?c ... _lig_dp_it

I got the manual from the vendor and it looks like it would work by setting (found on page 56 of attached manual)

P0-00 to 5: 9600 baud
P0-01 to 0: No parity
P0-02 to 1: Local Address of 1??

I'm just not sure how to setup all the functions and what not for the custom MODBUS option in tool settings

any help would be great as this looks like a rather good VFD

We do not currently support this VFD.

I took a look at the manual and it appears that they only support a multiword read command. This means that the read format does not appear to be compatible with the read format in the Buildbotics Controller. If this is true, then it is doubtful that we could make the interface work without a software change in the BB Controller.

After further review, I think we do stand a good chance of getting this going. I think the multi-word read issue is a non-issue.
