6.14.2 Master-slave torque control
In master-slave torque control, two motors (master and slave) are
mechanically coupled. Because of the coupling, only one position encoder is
required. The motor to which the position encoder is assigned is the master.
Axes can be controlled in pairs in the torque-master-slave-control, whereby
you must keep in mind that the master and slave axis must be on the same
speed controller circuit board.
In principle there are two applications:
Minimization of mechanical play through mutual tensioning
Distribution of torque with a rigid coupling
Minimization of mechanical play through mutual tensioning
Distribution of torque with a rigid coupling
