1. Some stepper motors may leak a magnetic field causing the AMT index pulse to not function properly.
2. All resolutions stated are before quadrature decoding. (example: 1000 ppr x 4 = 4000 counts)
3. Based on full production testing standards and includes all electronic and mechanical based errors, not a computed estimate.
