A reset eprom and fresh new machine config worked thanks
Ok i setted it at 9.99v If i set $30 at 1000 and send m3s1000 Everything work enven m3s500 speed goes down Send m5 spindle stop if i set $30 at...
Spindle turn off = incorrect VFD parameters (Min Freq) 0-3v is Spindle Off. 3-10v = 7200-24000rpm. Can't really send more than 10v if you...
Hi Peter, In regards to my comment about not needing to program the VFD, i was referring to the work around solution you proposed to find a way...
...is an old school analog circuit. 0.7 is well below 3V False. Min Freq is a critical safety parameter to prevent burning out spindles! And...

Thanks for your help Peter, I'll have another read through the VFD Manual to see if i can work it out which parameter i need to fix the issue....
That's a VFD config - something similar to Min Freq (set to 120Hz) You want the VFD to ignore 0-3v (0-7200rpm) and only start up from 7200-24000...
...ignore 0-3v / (0-7200 RPM = OFF, also sometimes 0-120hz) using a Min Freq parameter and ramp 3-10v as 7200-24000RPM / 120-400Hz so usually you...

That much is fine - and handled with the VFDs Min Freq setting Your other issue of slightly skewed RPMs (not too abnormal, it is an analog...
Hi peter, Here are the two values I find in the VFD parameters. What a parameter and what value I must write to reach the value of 7200 RPM. This...
Yes I have this model A2-8015. The connection to the BBX32 is below [ATTACH] [ATTACH]
Yes I have to see the RPM Min & Max again so that the Spindle does not start below 3000 RPM (I must be too low with my minimum setting, with the...
Duplicate post? Replied to questions above the repost Also, if that VFD doesnt have a min freq option, you might have to use VFD A2-8015 to BB x32
Forgot to setup the MIN FREQ parameter on VFD (only allow 7200 rpm plus for spindle's safety - does double duty as an OFF function) [ATTACH] 3...
Thats fine. A properly set up vfd will stop at +-3.0v already (10x higher). Setup Min Freq on the VFD itself correctly. Usually for 120hz/7200rpm min
I couldn't agree more this is probaly the most frustrated I've ever been setting a machine up. there seems to be very little as far as what the...
