fix addtorque command

Recently, I want to study the fix addtorque command.

I want to add a torque to rotate the spindle. So I write a few lines of the program about the addtorque command. But the spindle can’t rotate.

Thus, I want to receive some example files about the addtorque command so that I could imitate to write my own in.file.

Please as simple as possible, I am a new learner.

Thanks.
