Detailed description
2.1 Speed/torque coupling, master-slave (SW 6 and higher)
2.1.1 General information
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.
This function is mainly used for boosting the power of mechanically-coupled drives. Other
application: Compensation of gears and backlash in the gear tooth flank due to mutual
tension in the drives.
