Automatic Reset for Undervoltage is enabled or disabled, determining whether the drive will reset and resume operation after an undervoltage event. The manual's first action is: “• 0 = DISABLE – Disables automatic reset. • 1 = ENABLE – Enables automatic reset. • Automatically resets the fault (DC UNDERVOLT) after the delay set by 3103 DELAY TIME, and the drive resumes normal operation.”
