Conveyor drive with adjustable tension
[3-1] Example: Conveyor drive with adjustable tension
r The master drive is operated speed-controlled and determines the speed of the
material path.
r The slave drive with the standard technology application "actuator – torque" ensures
that a certain minimum tensile stress is complied with between master and slave drive.
When torque-controlled, the slave drive is permanently able to follow the speed
specified by the master drive.
