Apologies in advance if this is a naive question regarding how the RS485 connection works on the SLB, I have no experience with electronics or electricity - just trying to cobble together a BOM for a small DIY CNC mill.
I was hoping to use a Stepperonline 400W servo, which comes with it’s own driver that has a RS485 port. Can the SLB communicate with that just as it would with a VFD?
It would depend what sort of communication style the servo expects, since from my understanding it would either take the form of:
Typical ModBus over RS485 in which case if you can find the appropriate values in the user manual you should be able to set it up in the firmware as a custom spindle: run/stop register, set frequency register, get frequency register, CW command word, CCW command word, Stop command word, RPM value multiplier/divider for programming, RPM value multiplier/divider for reading
Using the much more experimental Stepper spindle option which we haven’t tested yet on the SLB
Using the SLBs A-axis output and changing your CAM post processor to control your spindle through A-axis commands
