Parameter mm.000

Parameter mm.000 (mm.000) is one parameter that can be accessed from every drive menu so that the user can initiate various actions by setting a value in this parameter and then performing a drive reset. If the action is completed successfully parameter mm.000 is cleared when the action is complete. If the action is not started because the value does not correspond to an action, or because the action is not allowed (i.e. an attempt is made to load defaults and the drive is enabled), parameter mm.000 is not cleared. If the action is started and then fails a trip is produced and parameter mm.000 is not cleared.

There could be some conflict between the actions of Parameter mm.000 (mm.000) and Parameter Cloning (11.042) when the drive is reset. If Parameter Cloning (11.042) has a value of 1 or 2 and a valid action is required from the value of parameter mm.000 then only the action required by parameter mm.000 is performed, but on successful completion of the action both parameters are cleared. If Parameter Cloning (11.042) has any other value it is not affected.

The table below shows the possible actions that can be initiated with Parameter mm.000 (mm.000).

Parameter mm.000 (mm.000) value Action Possible failures
1000 Save drive user save parameters to non-volatile memory. Power-down save parameters are saved when the drive enters the under voltage state.

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 and the standard under voltage threshold is being used (i.e. Low Under Voltage Threshold Select (06.067) = 0).

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 1000 in Parameter mm.000 (mm.000) if the drive is not in the under voltage state and the standard under voltage threshold is being used (i.e. Low Under Voltage Threshold Select (06.067) = 0).

OR
A drive reset with 1001 in Parameter mm.000 (mm.000).

OR
On the transition into the under voltage state when the standard under voltage threshold is being used (i.e. Low Under Voltage Threshold Select (06.067) is zero).

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 occur 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.
  4. When a new option module is fitted to the drive all the data is both banks in the non-volatile memory is cleared. The next parameter a save time is extended as the new parameter data is written to both banks.
  5. Two banks are not provided in non-volatile media cards therefore the card could be corrupted if the power is removed when the drive is writing data to the card.

Loading defaults
A drive reset with 1233 in Parameter mm.000 (mm.000) loads the defaults defined for each parameter. If defaults are loaded with 1244 in Parameter mm.000 (mm.000) then the parameters in the table below have different defaults that are intended for the 60Hz regions.

Non-volatile media card data transfer
Details of the data that can be stored on a non-volatile media card and the methods to transfer/access this data are given in Menu 11.

Stored HF trips
When the drive is subsequently powered up a Stored HF trip is initiated where the sub-trip number is the number of the HF trip that last occurred. This trip will occur at every power-up until it is reset. The trip can only be reset by first entering 1299 into Parameter mm.000 (mm.000). If the drive is powered up and a Stored HF trip occurs, Onboard User Program: Enable (Pr 11.047) is reset to zero to prevent the on-board user program from running. This ensures that the user program can be changed or erased in case it causes an HF trip at every power-up. Once the Stored HF is cleared, it is necessary to power cycle the drive or to re-download the user program to allow the program to restart.
