Torque between axis group members

The torque between axis group members is particularly important when tensioning chains, clamping workpieces, and minimizing backlash. The torque between two axis group members is explained in the following in more detail by means of the schematic view of a gear wheel that is driven by two axis group members.

If the torque between the axis group members is set to "0" and a setpoint torque of 120 Nm is required, both axis group members will deliver 60 Nm each.

However, if the torque between the two axis group members is set to 50% of the nominal motor torque, the second axis group member would deliver 90 Nm and the first one only 30 Nm. This would result in a torque difference of 60 Nm as a tension assuming that both motors have a nominal torque of 120 Nm each.

The direction of the tension is indicated by the sign of the torque ratio. If a tension of -50% of the nominal torque is defined without load, the first axis group member would deliver 30 Nm and the second one -30 Nm.
