If the drive indicates a fault, investigate the cause of the fault making sure proper
safety precautions are followed. Refer to Troubleshooting on page 183.
◆ Auto-Tuning
Auto-Tuning simplifies drive setup by automatically measuring motor equivalent
circuit values while energizing and rotating the motor to easily achieve optimized
performance.
■ Types of Auto-Tuning
There are three types of Auto-Tuning. Refer to Auto-Tuning Selection on
page 162 to select the best type of Auto-Tuning for the application.
Note: Auto-Tuning cannot be performed on permanent magnet motors (IPM, SPM, etc.).
