Selection of the torque setpoint in torque mode
In torque mode", the nTorqueGenLim_a application input has the function of the torque setpoint
selection.
The torque setpoint is usually defined as process date via the fieldbus. If set accordingly, the torque
setpoint can also be determined locally (e.g. via the analog input 1).
For the local selection of the torque setpoint, the same application input (nAuxSetValue_a) is used
as for the local selection of the speed setpoint. In "torque mode" however, the nAuxSetValue_a
input is internally connected to the nTorqueGenLim_a input. In this case, the speed setpoint is
internally permanently set to "100 %".
The relationships are shown in the following table:
