*Encoder resolution must be added based on the gearhead: 16:1 add ±122.72 µrad, 64:1 add ±30.68 µrad, 256:1add ±7.67 µrad, 1024:1 add ±1.92 µrad
**A higher gear reduction means a slower speed. Higher speeds (lower ratio) can be used, but at the expense of resolution and load/torque capacity.
†Dependent upon gear ratio backlash can be compensated in software without overshoot.
Note: The MM-3M stages are designed for peak performance at low loads: ex; 60g, less than 50.8mm off axis.
