When a parameter in Menu zero is changed via the keypad and Parameter Cloning (N01) = 3 the parameter is saved both to the drive non-volatile
memory and to the parameter file with identification number 1 on the card. Only the new value of the modified parameter, and not the value of all the
other drive parameters, is stored each time. If Parameter Cloning (N01) is not cleared automatically when a card is removed, then when a new card is
inserted that contains a parameter file with identification number 1 the modified parameter would be written to the existing file on the new card and the
rest of the parameters in this file may not be the same as those in the drive.
When Parameter Cloning (N01) = 3 and the drive parameters are saved to non-volatile memory, the file on the card is also updated, therefore this file
becomes a copy of the drive parameters. At power up, if Parameter Cloning (N01) = 3, the drive will save its complete parameter set to the card. This
is done to ensure that if a card is inserted whilst the drive is powered down the new card will have the correct data after the drive is powered up again.
4: Boot
When Parameter Cloning (N01) = 4, the drive operates in the same way as with Parameter Cloning (N01) = 3 and automatically creates a copy of its
parameters on the NV Media card. The NC (not clonable) attribute for Parameter Cloning (N01) is 1, and so it does not have a value stored in the
parameter file on the card in the normal way. However, the value of Parameter Cloning (N01) is held in the parameter file header. If Parameter
Cloning (N01) = 4 in the parameter file with a file identification value of 1 on an NV media card fitted to a drive at power-up then the parameters from
the parameter file with file identification number 1 are transferred to the drive and then saved in non-volatile memory. Parameter Cloning (N01) is then
set to 0 after the data transfer is complete.
It is possible to create a bootable parameter file by setting Pr mm00 = 2001 and initiating a drive reset. This file is created in one operation and is not
updated when further parameter changes are made.
When the drive is powered up it detects which option modules are installed before loading parameters from an NV media card which has been set up
for boot mode. If a new option module has been installed since the last time the drive was powered up, a Slot1 Different trip is initiated and then the
parameters are transferred from the card. If the parameter file includes the parameters for the newly installed option module then these are also
transferred to the drive and the Slot1 Different trip is reset. If the parameter file does not include the parameters for the newly installed option module
then the drive does not reset the Slot1 Different trip. Once the transfer is complete the drive parameters are saved to non-volatile memory. The trip
can be reset either by initiating a drive reset or by powering down and then powering up again.

Media Card File Number (N03) is used to select a file by its file identification number and can only be changed to values that correspond to files that
are recognized by the drive on the NV media card or a value of 0. When Media Card File Number (N03) corresponds to the number of a file the
following data about the file is shown.
Media Card File Type (N04)
Media Card File Version (N05)
Media Card File Checksum (N06)
The actions of erasing a card, erasing a file, creating a new file, changing a Menu 0 parameter or removing a card resets Media Card File Number
(N03) to 0.
