Gear unit

The parameters of the gear unit used are set via the "Gear unit" tab. More information can also be obtained from the tooltip ("i" symbol) for the respective parameter.

Parameter name

Description

Gear ratio

Specify torque ratio of the gear unit. Speed reduction ratio of the gear unit.

Constant friction

Specify static friction ratio of the entire drive train. The static friction ratio applies regardless of the speed.

Factor of speed-dependent friction

Select the assembly of the drive train on which the friction acts. This reference point has an effect on the gear ratios with which the friction is still calculated.

Smoothing factor of friction curve for direction of rotation reversal

Define the smoothing factor for 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 smooth the friction curve around the zero point of the motor speed.
