Brief description
SW 6.4 and higher
The function of the speed/torque coupling has been expanded to include the following
options:
• Coupling/decoupling of rotating, speed/controlled spindles
• Dynamic configuration of couplings
A separate machine data has been provided for reversing the direction of the slave axis in
coupled state.
Up to SW 5.x
The speed/torque coupling function (master-slave) is used for mechanically-coupled axes
that are driven by two separate motors. This function was available up to SW 5 only via a
technology card. It was not included in the standard scope of functions.
