(1) Ratio ( i = N in / N out)
(2) These values are measured by gearbox with ratio 55 (2-stage), ratio 385 (3-stage) or 5,500 (4-stage) at 3,000 rpm no loading.
(3) Backlash is measured at 2% of Nominal Output Torque T2N
(4) Applied to the output shaft center at 100 rpm.
(5) Continuous operation is not recommended.
