Note!
The losses have a relatively high constant proportion, i. e. the torque loss is almost irre-
spective of the load torque. The reason for this is the pretension of the belt, which is re-
quired if dynamic traversing with a high precision is to be carried out.
The DSD thus considers the efficiency to be entered as a constant torque. For the calcu-
lation always an efficiency at the highest load is assumed. Because of this definite di-
mensioning, no additional constant torque has to be specified.
