16.2 Coupling diagram
If the coupling is closed, the slave axis is traversed only with the load-side setpoint speed of
the master axis. It is therefore only speed-controlled, not position-controlled. There is no
differential position control between the master and slave axis.
The torque required between the master and slave axis is distributed using the torque
equalization controller. When using different motors, this distribution can be adapted to the
specific requirements using a weighting factor.
A tension can be established between the master and slave axes by entering a supplementary
torque (tensioning torque).
