In DTC induction motor module, what is the equation between the input: speed reference and torque reference produced in module

It is not very clear to me about input SP in DTC induction motor module. This is what is presented: SP The speed or torque set point. The speed set point can be a step function, but the speed change rate will follow the acceleration / deceleration ramps. If the load torque and the speed have opposite signs, the accelerating torque will be the sum of the electromagnetic and load torques.
But when I viewed the schematic of control block. It showed that torque reference is determined by speed reference. And I found when I put a step function to this input, the torque reference measured from the block was what I put to this input. In this case, it seems that SP is to set torque reference
So I am very confused about this input, I am not sure what it works for, torque reference or speed reference.

The input "SP" is used for setting either speed or torque setpoint. There are multiple demo models that depict the use of speed reference and torque reference in the same model.
>> cs_coupling_1.slx
>> cs_coupling_2.slx
>> cs_coupling_1_SSC.slx
>> cs_coupling_2_SSC.slx
These models will help you understand the usage both speed and torque setpoints.
