(2) Speed limit function
The speed limit is one of protective functions used during torque control.
This function regulates the motor speed so that it does not exceed the speed limit while
the torque is controlled.
While the speed limit is used to control the motor, the torque command applied to the
motor is not directly proportional to the analog torque command. Torque command
should have the following result: the motor speed is equal to the speed limit.
