The motor load torque is defined by CON(J+17) and CON(J+18).
Tload = Tnom*(1+deltaspeed)**D
Deltaspeed is -1 for a standstill motor. Normal values of load damping D is 1 or 2. You have entered a very small value, 0.03, which means that the load torque is too high at low motor speeds. The electrical torque is thereby lower than the load torque and the motor doesn't accelerate during the motor starting simulation.
Try with D=1. From where did you get the value 0.03?
