1) Force is controlled and evaluated by closed-loop control of the motor current. A torque level or a linear force can be determined from
the level of current measured depending on the mechanism of the drive. The target is set as a percentage of the rated motor current
and may deviate from the actual force on the drive unit. If force levels are set low, the influence of friction in the system on the
running behaviour and the actual force on the drive unit must also be taken into account.
