Let's analyze the differences and nuances between the sentences, and then determine which is most common or typical in technical contexts and which should be avoided.

1. The controller controls a drive of the motor based on a control signal.

   • Meaning/Nuance: This suggests that the controller controls one of possibly several drives of the motor. It is somewhat specific but implies that there may be multiple drives.
   • Usefulness: This is less typical because it suggests the existence of multiple drives, which might not be the intended meaning.

2. The controller controls drive of the motor based on a control signal.

   • Meaning/Nuance: This sentence is less specific because it lacks the definite article "the" before "drive," making it sound somewhat incomplete or general.
   • Usefulness: This is less conventional and might be avoided due to its vague nature.

3. The controller controls the drive of the motor based on a control signal.

   • Meaning/Nuance: This sentence is clear and specific, referring to a particular drive mechanism of the motor that the controller controls.
   • Usefulness: This is a common and conventional way to describe the action in technical documents.

4. The controller controls driving of the motor based on a control signal.

   • Meaning/Nuance: This refers to the action or process of driving the motor. It is a bit more abstract compared to "the drive."
   • Usefulness: This can be used but is less specific than sentence 3. It is acceptable but not as precise.

5. The controller controls the driving of the motor based on a control signal.

   • Meaning/Nuance: This is similar to sentence 4 but more specific due to the definite article "the." It refers to the particular process of driving the motor.
   • Usefulness: This is also clear and specific, making it a good choice in technical contexts.

Most Common or Typical in General Technical Context:

• Sentence 3: "The controller controls the drive of the motor based on a control signal."
  • This sentence is specific, clear, and conventional, making it the most typical choice in technical documentation.

Sentence to Avoid:

• Sentence 2: "The controller controls drive of the motor based on a control signal."
  • This is vague and less grammatically conventional, making it less suitable for technical documents.

In conclusion, for clarity and conventional usage in technical contexts, Sentence 3 is the best choice. Sentence 2 should be avoided due to its vagueness.
