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 |

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 OR OR OR OR |
User save parameter visible in menu 0 | Under the conditions given above for user save parameters not visible in Menu 0.
OR |
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 OR OR OR |
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:
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.
Parameter | Default | Drive modes | Drive voltage rating |
Maximum reference clamp (01.006) | 60.0Hz | Open-loop | All |
Maximum reference clamp (01.006) | 1800rpm | RFC-A | All |
Standard Ramp Voltage (02.008) | 775V | Open-loop, RFC-A, RFC-S | 400V |
Rated Frequency (05.006) | 60.0Hz | Open-loop, RFC-A | All |

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.
