Drive train

To physically simulate the motor torque, the inertia and friction properties of the drive train must be configured. During the process, the values for the motor are already taken from the drive train. Gear unit ratios and friction still need to be parameterized.

INFORMATION: To ignore individual components of the drive train or the friction in the software, set their parameter to "0".

Friction (see also chapter Systematically measuring friction)

Constant friction

Static friction ratio of the entire drive train in relation to the reference point of the friction. The static friction ratio applies regardless of the speed.

Reference point of friction (input end)

The friction of the entire drive train is calculated based on the speed acting at the reference point. The reference point is the input of the selected drive train assembly. This reference point has an effect on the gear ratios with which the friction is still calculated.

Factor of speed-dependent friction

Dynamic friction ratio of the entire drive train in relation to the reference point of the friction. The dynamic friction ratio constitutes the speed-dependent friction components.

Smoothing factor of friction curve for direction of rotation reversal

The smoothing factor describes the transition of the entire drive train during a speed reversal. The smoothing factor "0" causes a sharp surge in the frictional torque and thus the motor torque during a change in speed, which does not correspond to actual behavior. To reduce the steepness of these surges, this factor can be used to smoothen the friction curve around the zero point of the motor speed.
