Functional Description

Is used to display the torque constant of the motor [Nm/A] (is read from the motor encoder) for low currents. For currents above the rated current, the torque constant reduces due to saturation effects in the motor. This effect is taken into account when calculating the maximum acceleration MaxAcc.

NOTE: The parameter value is transferred from the slave to the master via the parameter channel of the Sercos by every access. Typically, this takes about 10 ms. By a high capacity of the parameter channel, times up to 1 s can occur. If the Sercos bus is in phase 0 or 1, then a standard value is indicated here. If the Sercos bus is in phase 3 or 4, then the parameter value is transferred and indicated. In the Sercos phase 2, the parameter can be read through the application.
