Retrofitting a 1986 Maho MH400E

Good shot with the USB stick down the elevator gap. Couldn't do it again if you tried

Whn you talk of "Spindle at speed" signal, was this signal generated from that encoder, or frm the VFD, or is it just an assumed value based on the worst case time for the spindle to accelerate. The MAHO set up can't generate that signal as built can it?

Those are the encoders for the servos.

This is the vector drive for the spindle motor

And the brake of the spindle motor

Spindle at speed is an control input to LinuxCnc it is binary (1 or 0) if it is 0 than the LinuxCnc holds the feeds on all axis, if it is 1 than the motion is continued again. The encoder is fed directly to LinuxCnc, and LinuxCnc synchronizes the motion for every job that needs sinc motion with spindle.

The VFD has a relay output spindle at speed, I can connect it to mesa and connect the two signals with “and” in hall file, or in ladder. The maho originally I don’t think that it had speed at speed, I think it had timers on the controller.

I think that Spindle at speed is intended to be connected like this (to vfds), so LinuxCnc knows that the vfd has reached the commanded speed.

Can I put on the setp encoder.0.position-scale instead of a number, a signal that is connected to an output off ladder to scale correct the selected gear. And not connect the index
