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.
