Servo Overheat

[m_c]

Changing the micro-stepping setting won't have any practical effect on torque at the motor when moving.

The Leadshine website isn't working for me just now, but don't AM drives have stall detection?
Do you have the error outputs connected, so you know if a drive has faulted?

Yeah they have stall detection, but it only operates when / if my motors are above 3000 mm/min. And due to my cut rate being 5000, then I can summize, that the error must be occuring at lower speed prior to stall detect kicking in, IE on decel / acceleration.


I came up with my numbers by trial and error, finding the max unloaded speed with low acceleration, then the max acceleration to low speed with lots of reversals. , and setting a % of this, like 50 as the max machine settings.

Did some more testing to check the acceleration settings - Checks performed at 8000 mm/min
Y axis failed at 1100 mm/s/s Now set at 550
X axis failed at 1600 mm/s/s Now set at 800. ( this is the axis that jammed, but was also doing most of the work at the time )




Servo case temp - could touch case for 5/6 seconds, and my turkey cooking probe was at 52 degrees C

That case temp sounds fine to me. Out of the four steppers on my router, three spent the best part of five years driving my previous machine, usually at or around that sort of case temp. They are all working fine still!
