Siemens SIMOTICS L-1FN3 Configuration Manual page 133

Depending on how far this transverse axis is moved out of the center position, the slide mass
m is distributed between both motors of the gantry axis. This means that in addition to half
S
the mass of the gantry, the individual motor also has to move the percentage mass of the
transverse axis slide.
It is sufficient to use the most unfavorable scenario when dimensioning the two motors.
In this case, the slide of the transverse axis is fully moved to one side. For reasons of
simplicity, the maximum possible movement at both sides is assumed to be identical.
The equivalent mass m

The drive is now dimensioned based on the equivalent mass - and is only carried out for one
motor. The result is also valid for the other motor.
