Title: Vfd power safety output
Post by: DAAD on November 22, 2020, 07:56:47 AM

Hello,

Because my spindles are setup on a second control box i would like to add a safety feature in my m6 macro.
I would like it to check if there is power on the vfd, but honestly i would not know where to start or whats done best in this situation.
I would like to rule out operation error if someone forgets to power on the spindles...
 
Is there a signal i can "get" from the vfd this way i can program an input around this that needs to be checked before the gcode can start.

Keep Safe,

Adam

Ok!

Will look into the vfd manual for an "OK" output!

Thanks for pointing me in the correct direction!

I was able to get an input for the VFD to mach' and have adjusted my cycle start so i can't start without power onto the spindles.

Thanks for the tip!

Keep Safe,

Adam
