Spindle - 7i76e

Hello,

I am useing:
linux mint, linuxcnc, mesa7i76e , VFD Huanyang

I have problem:
with Spindle - pin2 on TB4 is stil 0.14V and not increase..(like potentiometer)



+10 to Pin 3
VI to pin 2
ACM to Pin 1

FOR to Pin 6
REV to Pin 8
DCM to Pins 7 and 5

Then Configure the VFD
PD001 = 1
PD002 = 1
PD044 = 1
PD045 = 5

Thank you

When you test, what are the values of these hal pins?

hm2_7i76e.0.7i76.0.0.spinout
hm2_7i76e.0.7i76.0.0.spinena

Also did you measure 10V at 7I76E TB4 pin 3 relative to TB4 pin 1?

Yes 10V was there, hmm ok it is working now, probably i had linuxcnc switched still ON and restart only mesa and VDF.
Now mesa working well. (good Volt in pin 2... 1,6 4000rpm 0,8 2000rpm.... sorry to bother you)

But still have problem with VDF , it is reacting only to FOR and STOP
Not reaction on ,speed , REF. Interesant


Anything else to set on VDF :

Then Configure the VFD
PD001 = 1 (external terminal)
PD002 = 1 (external potentiometer)
PD044 = 1 (for RUN)
PD045 = 5 (FOR /REW)

Is this correct ?

Yes you would normally need to configure the VFD for RUN/DIR mode
rather than FWD/REV mode

(btw , thanks for helping PCW !!!!)

Perfect after many tries also RUN/DIN is running
Last thing to fix control by Mesa potentiometer ... stil can be up/down only manually on VDF.

Mesa giving Volts, but cannt be controled by linuxcnc. Trying and studing VDF, must be there.. somewhere..

Shit , two news:

1) great , all function on:

Then Configure the VFD
PD001 = 1 (external terminal)
PD002 = 3 (which was not in manual)
PD044 = 1 (for RUN)
PD045 = 5 (DIR.......FOR /REW)

2) Spindle burned
- otherwice watter flow thru spindle , spindle burned and is KO

Is any difference , which is IN and OUT for watter ? Or orientation of spindle (i had it on floor- flat)
It flows tru then thought that it is ok
