Cause : Rescue Operation Rotor Polarity Detection Warning- While operating from the backup battery, the Id value between poles was less than 5%. For Rescue Operation, either switch to a larger battery (at least 280 Vdc for a 200 V class drive, 560 Vdc for the 400 V class) or switch to an absolute encoder and the PG-F3 option card.
