Help with Eumach MC-800P retrofiting to OAK.
Posted: Tue Aug 31, 2021 10:24 am
Hello everyone,
I need some help getting my cnc retrofit project to work.
The machine is an Eumach MC-800P retrofitted with OAK and using the Oem Simodrive 611 to control the servos and the spindle. the servos is fitted with centroids 10000line encoders. For now i have the servos not attached to the machine to test them but I'm having problems to get the oak to send out the +-10v to drive them. i have the flying leads cable.
The thing i need help with right now is the how and what to connect to the Simodrive 611 to get it all to work correctly?
Since the servo drives needed +24v to enable i had to use a solid state relay between the flying lead and the drive. The problem now it seams is that it takes to long to enable the drive so i get a drive fault, but if i latch the drive enable signal i get the solid state to hold and then i can take the latch away and it works fine. so i think the fault input needs to be on some millisecond delay timer?
I did get the spindle to run cw and ccw with the +-10v but having som problems on the spindle brake "fast stop". it seems that i have to use an output to enable/disable that function, is that possible?
Here is a link to all the manuals, pic and schematic of the machine.

Hope someone can help me in the right direction with my project.
