Servo Overheat

[dachopper]

My specs below...

If I reduce the microstepping amount, say from 3200 steps/rev to 1600 or 800 steps/rev, that will increase resolution, but will it provide any greater torque using the AM882?

100 RPM 190 N cm 1000mm/min
300 RPM 174 N cm 91% 3000mm/min
500 RPM 150 N cm 80% 5000mm/min
700 RPM 120 N cm 63% 7000mm/min
750 RPM 105 N cm 55% 7500mm/min
800 RPM 85 N cm 45% 8000mm/min

RAPIDS / ACCEL SETTINGS
X 8000, Accel 1200, single motor ~30 kgs....... 10mm pitch
Y 7500, Accel 1000, dual motor ~ 60-70kgs..... 10mm pitch
Z 3500, Accel 1200, single motor ~ 15-20 kgs.. 5mm pitch
