2 Parameter x.00
Pr x.00 (not Pr 0.00) is available in all menus and has the following functions:
1000 Save parameters
1070 Option reset
2.1 Saving parameters
When parameters are saved, all user save (US) parameters are saved to EEPROM within the drive. Normally Pr x.00 (not Pr 0.00) is set to 1000 and
a reset command is given to initiate a parameter save. This can be achieved on the drive by setting Pr 71 to 1.00, then setting Pr 61 to 1000 and a
reset command to activate a parameter save. When parameter save is complete, Pr x.00 is reset to zero by the drive. The drive must not be in the
under voltage (UU) condition for a save to take place. Saving parameters can take between 400ms and several seconds depending on the number of
parameter values that are different from the values already saved in EEPROM. If the power is removed from the drive during a parameter save, it is
possible for the EEPROM data to be corrupted giving an EEF failure when the drive is next powered up.
2.2 Loading default parameters
When default parameters are loaded, the new default parameter set is automatically saved to the drive EEPROM.
See Pr 29 in the Commander SK Getting Started Guide or Pr 11.43 in this Advanced User Guide.
