Saving drive parameters
User-save and power-down save drive parameters are stored in non-volatile memory within the drive. Any values that have changed are copied to this
memory under the following conditions.
Parameter type Conditions for copy to non-volatile memory
User-save parameter not visible in
menu 0
Drive reset with 1000 in Parametermm.000 (mm.000) if the drive is not in the under voltage state.
OR
A drive reset with 1001 in Parametermm.000 (mm.000).
OR
After parameters are transferred from a non-volatile media card.
OR
After the drive mode is changed.
OR
After default parameters are loaded.
OR
After parameters are transferred from an electronic nameplate.
User save parameter visible in
menu 0
Under the conditions given above for user save parameters not visible in Menu 0.
OR
If the keypad is in edit mode for a user-save parameter in Menu 0, the parameter is saved when the keypad mode
is changed from edit mode.
Power-down save parameter
A drive reset with 1001 in Parametermm.000 (mm.000).
OR
On the transition into the under voltage state.
OR
After the drive mode is changed.
OR
After parameters are transferred from a non-volatile media card which results in the drive mode changing.
It can take some time for parameter data to be copied to non-volatile memory, especially if there are a large number of differences between the
parameter values in the drive and the values stored in the memory. Saving Power-down save parameters takes a maximum of 300ms, but saving user-
save parameters can take several seconds. If the drive is powered from a 24V control supply, or from a low voltage supply, the power down time of the
control system can be very short and there is a risk that either the stored values of the power-down save or user-save parameters could be corrupted.
This would result in an EEPROMFail trip at the next power-up. To reduce this risk, the power-down save and user-save parameters are each stored in
two banks. The banks are alternated each time a save is performed and the bank pointer is only updated once the save is complete. If the new bank is
corrupted a UserSave or PowerDownSave is initiated at the next power-up indicating an error in the user-save or power-down save data respectively,
and the data from the old bank is used. The following points should be noted:
1. If a UserSave or PowerDownSave trip occurs at power-up then parameter changes made before power down will be lost. To clear these trips
a parameter save must be performed. If both the user-save and power-down save data is corrupted then a PowerDownSave trip is produced.
2. When a Menu 0 parameter is changed its value is saved immediately to the active bank and the bank pointer is not changed. Therefore
changes made via Menu 0 are not lost if a UserSave trip occurs at power-up.
3. When the drive mode changes all the data in both banks in the non-volatile memory is cleared and the default parameters are saved in both
banks. Therefore there is an extended parameter saving period immediately after a drive mode change.
