M 2max, G – Maximum output torque of the gearboxcomponents

This torque must not be exceeded during operation. It ispermissible for a maximum of 30000 revolutions of the output shaft.An endurance strength configuration of the gearbox becomesnecessary, if the output torques up to M2max, G areused (see Configuration Manual).

M 2Em.Off – Emergency Off output torque of the gearboxcomponents

The Emergency Off torque can be tolerated a maximum of 1000 timeswithin the gearbox service life without causing unacceptable damageto the gearbox. This code can be used to check whether the torques,caused by very rare operating faults, can damage the gearbox.

M 2Em.Off – Emergency Off output torque of the gearboxcomponents in Nm

η G – Efficiency of the gearbox components under fullload

The exact values for the efficiency are, to some extent, dependenton the frame size of the mounted motor and can be found in the datasheet resulting from the configuration on the Siemens ProductConfigurator.
In the partial load range, especially when the gearbox is cold, theefficiency of the gearbox is always lower than at operatingspeed.
The gear losses are already taken into account in thecharacteristic curves and in the following characteristic data ofthe geared motor or itscomponents: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics onefficiency is not necessary.
