* Only a value of 3 or 4 in this parameter is saved.
Parameter Cloning (11.042) can also be used to initiate data transfer to or from an NV media card as described below for each possible value of this
parameter.
1: Read
Provided a parameter file with file identification number 1 exists on the NV media card then setting Parameter Cloning (11.042) = 1 and initiating a drive
reset will transfer the parameter data to the drive (i.e. the same action as writing 6001 to Parameter mm.000 (mm.000)). When the action is complete
Parameter Cloning (11.042) is automatically reset to zero.
2: Program
Setting Parameter Cloning (11.042) and initiating a drive reset will transfer the parameter data from the drive to a parameter file with file identification
number 1. This is the same action as writing 4001 to Parameter mm.000 (mm.000) except that the file will be overwritten if it already exists. When the
action is complete Parameter Cloning (11.042) is automatically reset to zero.
3: Auto
Setting Parameter Cloning (11.042) = 3 and initiating a drive reset will transfer the parameter data from the drive to a parameter file with file
identification number 1. This is the same action as writing 4001 to Parameter mm.000 (mm.000) except that the file will be overwritten if it already exists.
When the action is complete Parameter Cloning (11.042) remains at 3.
If the card is removed when Parameter Cloning (11.042) = 3, then Parameter Parameter Cloning (11.042) is set to 0, which forces the user to
changeParameter Cloning (11.042) back to 3 if auto mode is still required. The user will need to set Parameter Cloning (11.042) = 3 and initiate a drive
reset to write the complete parameter set to the new card.
When a parameter in Menu zero is changed via the keypad and Parameter Cloning (11.042) = 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 (11.042) 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 (11.042) = 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 (11.042) = 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 (11.042) = 4 the drive operates in the same way as with Parameter Cloning (11.042) = 3 and automatically creates a copy of
its parameters on the NV Media card. The NC (not clonable) attribute for Parameter Cloning (11.042) 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 (11.042) is held in the parameter file header. If
Parameter Cloning (11.042) = 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 (11.042) is then set to 0 after the data transfer is complete.
It is possible to create a bootable parameter file by setting Parameter mm.000 (mm.000) = 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 fitted before loading parameters from an NV media card which has been set up for
boot mode. If a new option module has been fitted 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 fitted 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 fitted 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.
