DigitaxHD Power Down Save

The DigitaxHD drive requires a separate 24Vdc user supply.  As such if 24Vdc power is removed when mains AC power is removed it is not recommended to perform a power down save, either via 1001 code or in a user program.  When the 24Vdc user supply is removed there is only a 300ms hold up time and this is usually not long enough for the drive to complete a full power down save, especially if the 24Vdc supply is loaded.  Failure to follow this recommendation could lead to EEPROM.2, User Save or Power Down Save trip.
