huanyang vfd & linuxcnc 2.7

I can't set the rpm, spindle rotates constantly at 3000rpm.
M3 s10000 starts the motor but at 3000rpm not 10000rpm.
PD01=2 / PD02=2
Any solution for this ?

How exactly is the rpm off?
is it 7000 rpm offset at all commanded speeds?
is it 3.33333 times as much as you command?

What is your VFD model #, and what kind of spindle did you get (rpm and KW)
tell me your PD settings for:

PD003
PD004
PD005
PD007
PD008
PD141
PD142
PD143
PD144

tell me your PD settings for:

PD003=0.0
PD004=400
PD005=400
PD007=0.50
PD008=220
PD141=220.0
PD142=5.0
PD143=02
PD144=3000

Huanyang hy20d223b spindle 800w 220v 5a 24000rpm 400hz.
motor rotates at pd144 setting independely from that i set in linuxcnc

based on the description of PD003. it shouldnt matter what it is set at, they describe it as a default operating frequency.
However, I would set it to 400 and see if that takes care of your problem.

Your other settings look ok.

The definition of pd144 is the motor rpm @ 50 hz. For a 24k rpm 2 pole motor, this should be 3000.
Not sure why you are stuck at 3000rpm.

can you record what the vfd shows for frequency and rpm, as well as what linuxcnc shows for speed.

i set PD003=400 but no change
linuxcnc shows correct rpm the same with the vfd.Also correct other infos.
All are correct but can not set the rpm runs constantly at 3000rpm.
One other thing is that PD02 goes from 0 to 3 and manual writes nothing about 3 option if i set it to 3 then
spindle runs constantly to 10000 rpm and accepts commands from linuxcnc like 2 option.

Here the 15 line github.com/bebro/linuxcnc-huanyang-vfd/b...s/custom_postgui.hal
has comment.
If i remove comment linuxcnc do not start.

I think will go with the classic solution with 2 relays for cw ccw and pwm 0-10v for setting speed.

The commented-out line appears to be the one that sends the frequency command to the VFD, so that seems like an adequate explanation of why it isn't working.

Un-comment the line and see exactly what it is that LinuxCNC complains about. It will either be that a pin is already connected somewhere else, or a pin-name has been spelled wrong.

Fix the problem and you should be there.
