| Notes: |
| 1) The lead values
shown above in both travel rate and resolution calculations, are for 80
(1/80) Thread per Inch (TPI) leadscrews. For a 40 TPI leadscrew, substitute
0.025 inch lead. |
| 2) Max travel
rate calculated with motor armature running at a maximum speed of 20,000
RPM |
*The resultant
quadrature output is equal to 64 encoder counts per motor armature revolution.
