Retrofitting a 1986 Maho MH400E

I think the ''setp motion.spindle-on false'' approach is beter.

Can a comp even set a parameter directly? I thought the way the HAL works is that the comp connects to the rest of the hal through pins, so a comp can not change a setting it is not connected to though a pin.

When the gearbox comp wants to stop the spindle, it sets

to 1

I netted that to , but if I changed that net to and invert it , it should do the same thing, but free up my halui.spindle.stop pin for my external button shouldn't it?

Sorry John, I didn't get to that transformer question over the weekend.

Hi John,

I pulled the cover and had a look.





In the schematic of my machine, that point is marked mP, which might be Messpunkt (point to take measurements). At least there are defined measuring points on the relay board called MP with a number in a circle.

.

I left it open for now, so if you need better pictures or a different angle, just let me know.

Thank you very much.

Hi all, I think Mp rather means "Mittelpunkt" middle point as this is the middle of the symmetrical winding. The Indramats need symmetric supply, the DC motor is connected between Mp and the Thyristor Half-Bridge, swinging that end to either +140V or -140V. To achieve accurate response, windings have to be symmetric in number of windings and impedance.
