PWNCNC MODBUS issue

High all, I am having issues controlling my spindle through Gsender. I keep getting an Alarm 14, Spindle at speed timeout. I can get the spindle to spin up to speed, but in a couple seconds I get this alarm.

To be honest, I am a bit disappointed. The VFD was supposed to be preprogrammed for modbus control for the SLB. It wasn’t. Also, the instructions for the wiring are conflicting and very vague. I printed version that came with the unit showed the modbus connection on the VFD opposite from what was on their website.

It would help to insert links to the conflicting information.

I finally have it figured out and working. I saw an instruction that said if the SLB had a relay on it that I would have to set 340 to 5, and if it didn’t have a relay on it set it to 0. Mine has a relay, so I set it to 5. I had a guy in another forum suggest I switch it to 0. That did the trick.

@tresguey I was confused by the title of your link. I thought that the doc that you attached was from Sienci. As you know, it’s not. You may want to contacnt PWCNC to alert them to the incorrect information.
