(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 ourput flange center at 100 rpm.
(5) Continuous operation not recommended
