Variant 1: Motor calculation
Enter motor data
The motor data relevant to the calculation must be entered manually from the
data sheet.
Click on “Start calculation”.
If the moment of inertia of the motor
P 461 - Mot_J
is not known, a value
roughly corresponding to the motor's moment of inertia must be applied.
The calculation process
can
be
monitored
on the Moog
