Function
The speed/torque coupling function (master-slave) is used for mechanically-coupled axes
that are driven by two separate motors.
Additional applications:
● Compensation of gear backlash and backlash in the gear tooth flank due to mutual
tension in the drives
● Coupling/decoupling of rotating, speed-controlled spindles
● Dynamic configuration of couplings
Speed/torque coupling (master-slave) is a speed setpoint coupling between a master and a
slave axis, involving a torque compensatory controller for even torque distribution.
