1. Ratio ( i = N in / N out )
2. Backlash is measured at 2% of Nominal output torque T2N.
3. These values are measured by gearbox with ratio = 10 (1-stage) or ratio = 100 (2-stage) at 3.000 rpm without load.
4. Applied to the output flange center at 100 rpm.
5. Continuous operation is not recommended.
