Altivar 320 Variable speed Drive: Autotuning Status Resets to "Not Done" After Power Loss (Why?)

On Altivar Process and Altivar Machine products, the auto-tuning state goes always to "not done" when the drive is switched off. But motor data measured by previous auto-tuning are stored in the drive, so no need to worry. ATV keeps the tuned motor data until new autotuning or manual modification of motor data is done.
