Question:

Our factory has a continental 590 control DC motor used in extrusion machine,

when I use armature voltage feedback (host start speed 50, normal can produce 10It is normal to start at 80 or 150 of the speed, but after a few minutes the motor does not turn. 590 alarm (missing pulse alarm). When I change the feedback mode to speed feedback, my host sometimes starts and sometimes fails to start. I hope you help me, how should I adjust?. Thank you。

Answer:

You can adjust the proportional gain, and if you don't move, the parameter has this problem, you should check to see if you really lost the pulse
I've also encountered (missing a pulse alarm), and finally checked out is a SCR triggered, impassability, you can try
