1. A packaging machine, comprising:
a foil transport device including a drive unit; and
a controlling system for controlling an operation of the drive unit of the foil transport device, wherein the controlling system is designed to activate the drive unit during a production run of the packaging machine based on a speed- and/or temperature-dependent friction moment characteristic curve detected by means of a rotationally driven measurement run carried out by the drive unit, wherein the controlling system is designed to determine a measurement run temperature of the drive unit rotationally driven during the measurement run, and wherein the controlling system is configured to determine, based on a friction moment-temperature characteristic curve stored to the controlling system for the drive unit, a temperature compensation factor for the activation of the drive unit which is derived therefrom in view of a currently detected operating temperature of the drive unit and in view of the measurement run temperature detected during the measurement run.
