Fanuc minimum alowable spindle speed to 0

[GoetzInd]

Hey guys. I'm trying to use a coolant driven RAH holder on Fanuc HMC. Mc posts out the S0 M05 alright but the machine will alarm out citing the below minimum spindle RPM. Is there a parameter that controls this? I see one for max spindle speed but no min.

 

TIA

Okay, I am going to ask a dumb question. So why are you calling out an "S0" amd shuting off the spindle with an "M05"? I would think it would be okay just to call the "M05" without the "S0".

That would require post mod. Which is my plan B

#3735 is the minimum clamp speed of the motor it should currently be set for a value that is you current minimum commanded rpm check it first before you change anything

The paramater you may want to look at is Spindle SPeed Arrival Check (SAR) #3708.0

 

We have to change this parameter on some machines machines with spindle probes to allow the axes to move with no spindle speed active.

Thanks Guys,

Tried both those and still no luck. Looks like post mod.
