Here, the following applies: Tmech. req. ≤ T2N or Tth. req. ≤ T2N T2N = nominal torque of the transmission on the slow-running shaft. For gearbox motors, the total operation factor is calculated as follows: fB tot = fB x fH x fE x fT x fL x fS ≤ fV The total operation factor calculated for each individual case of operation may not exceed the permissible output factor fV. For all gearbox motors, the permissible output factor fV is indicated in the output speed output overviews.
