9.2.2 Detailed Design Procedure
1. See the Design Requirements section and make sure your system meets the recommended application
range.
2. See the DRV10983-Q1 Tuning Guide and measure the motor parameters.
3. See the DRV10983-Q1 Tuning Guide. Configure the parameters using the DRV10983-Q1 GUI, and optimize
the motor operation. The Tuning Guide takes the user through all the configurations step by step, including:
start-up operation, closed-loop operation, current control, initial positioning, lock detection, and anti-voltage
surge.
4. Build your hardware based on Layout Guidelines .
5. Connect the device into a system and validate your system solution.
