1000 Series Drive Speed Search Application Note

This document provides a comprehensive guide for configuring and troubleshooting the Speed Search function in Yaskawa 1000 series drives, which allows a drive to detect and synchronize with a coasting motor's speed and direction before ramping to the frequency reference. It details three Speed Search methods (Current Detection, Speed Estimation, and Current Detection 2), their recommended applications, basic setup procedures, and solutions for common faults like overcurrent, overload, and overvoltage.
