CCW dosen´t Work

Hello everyone,

First of all, many thanks to the forum and the many helpful contributions. Thanks to you, I almost got an old Emcotourn 340 working again.

I just can't get the spindle's CCW to work.

With CW the control gives me everything.

With CCW, the spindle brack signal comes briefly and then signals that the spindle has reached speed. But nothing turns.the other signals don't come on either.
 Maybe someone can tell me what's wrong in the ini or hal. Thank you very much and best regards Sebastian
 

Use the 'Halshow' tool and watch these signals when trying to run the spindle CCW:

net spindle-index-enable <=> pid.s.index-enable
net spindle-enable => pid.s.enable
net spindle-vel-cmd-rpm => pid.s.command
net spindle-fb-rpm-abs => pid.s.feedback
net spindle-output <= pid.s.output

Post a screenshot so we can have a look.

Without getting in to hardware diagnostics, first thing I'd try is editing the INI file.

Change [SPINDLE]:
To: [/code]

And see if that helps.  I assume you're using a 0-10v analog signal the the spindle motor VFD.  I suggest setting up a halshow watch list that includes all the spindle output signals/pins, including the output voltage to the VFD.

You seem to be about 10 seconds ahead of every response I type!image missing /media/kunena/emoticons/smile.png

But your diagnostic seems more informed than mine.

The spindle analog settings are for a -10V to +10V controlled spindle
If you have a 0 to +10V controlled spindle you will need to replace

net spindle-vel-cmd-rpm => pid.s.command

with

net spindle-vel-cmd-rpm-abs => pid.s.command

and use a separate digital output to control the spindle direction
