4yyy - Write default differences to a SMARTCARD
The data block only contains the parameter differences from the last
time default settings were loaded.
Six bytes are required for each parameter difference. The data density is
not as high as when using the 3yyy transfer method as described in the
previous section, but in most cases the number of differences from
default is small and the data blocks are therefore smaller. This method
can be used for creating drive macros. Power-down save (PS)
parameters are not transferred to the SMARTCARD.
All user save (US) parameters including those that do not have a default
value (i.e. Pr
3.25
or Pr
21.20
Encoder phase angle
), but not including
those with the NC (Not copied) coding bit set can be transferred to the
SMARTCARD. In addition to these parameters all menu 20 parameters
(except Pr
20.00
), can be transferred to the SMARTCARD even though
they are not user save parameters and have the NC coding bit set.
It is possible to transfer parameters between drives with each of the
different formats, however, the data block compare function does not
work with data produced by different formats.
Writing a parameter set to the SMARTCARD (Pr 11.42 = Prog
(2))
Setting Pr
11.42
to Prog (2) and resetting the drive will save the
parameters to the SMARTCARD, i.e. this is equivalent to writing 3001 to
Pr
xx.00
. All SMARTCARD trips apply except 'C.Chg'. If the data block
already exists it is automatically overwritten. When the action is
complete this parameter is automatically reset to nonE (0).
10.2.2 Reading from the SMARTCARD
6yyy - Read default differences from a SMARTCARD
When the data is transferred back to a drive, using 6yyy in Pr
xx.00
, it is
transferred to the drive RAM and the drive EEPROM. A parameter save
is not required to retain the data after power-down. Set up data for any
Solutions Modules installed are stored on the card and are transferred to
the destination drive. If the Solutions Modules are different between the
source and destination drive, the menus for the slots where the
Solutions Module categories are different are not updated from the card
and will contain their default values after the copying action. The drive
will produce a 'C.Optn' trip if the Solutions Modules installed to the
source and destination drive are different or are in different slots. If the
data is being transferred to a drive of a different voltage or current rating
a 'C.rtg' trip will occur.
The following drive rating dependant parameters (RA coding bit set) will
not be transferred to the destination drive by a SMARTCARD when the
rating of the destination drive is different from the source drive and the
file is a parameter file (i.e. created using the 3yyy transfer method).
However drive rating dependent parameters will be transferred if only
the current rating is different and the file is a differences from default
type file (i.e. created using the 4yyy transfer method). If drive rating
dependant parameters are not transferred to the destination drive they
will contain their default values.

Reading a parameter set from the SMARTCARD (Pr 11.42 =
rEAd (1))
Setting Pr
11.42
to rEAd (1) and resetting the drive will transfer the
parameters from the card into the drive parameter set and the drive
EEPROM, i.e. this is equivalent to writing 6001 to Pr
xx.00
. All
SMARTCARD trips apply. Once the parameters are successfully copied
this parameter is automatically reset to nonE (0). Parameters are saved
to the drive EEPROM after this action is complete.
N
This operation is only performed if data block 1 on the card is a full
parameter set (3yyy transfer) and not a default difference file (4yyy
transfer). If block 1 does not exist a 'C.dAt' trip occurs.
10.2.3 Auto saving parameter changes (Pr 11.42 =
Auto (3))
This setting causes the drive to automatically save any changes made to
menu 0 parameters on the drive to the SMARTCARD. The latest menu 0
parameter set in the drive is therefore always backed up on the
SMARTCARD. Changing Pr
11.42
to Auto (3) and resetting the drive will
immediately save the complete parameter set from the drive to the card,
i.e. all user save (US) parameters except parameters with the NC coding
bit set. Once the whole parameter set is stored only the individual
modified menu 0 parameter setting is updated.
Advanced parameter changes are only saved to the card when Pr
xx.00
is set to a 1000 and the drive reset.
All SMARTCARD trips apply, except ‘C.Chg’. If the data block already
contains information it is automatically overwritten.
If the card is removed when Pr
11.42
is set to 3 Pr
11.42
is then
automatically set to nonE (0).
When a new SMARTCARD is installed Pr
11.42
must be set back to
Auto (3) by the user and the drive reset so the complete parameter set is
rewritten to the new SMARTCARD if auto mode is still required.
When Pr
11.42
is set to Auto (3) and the parameters in the drive are
saved, the SMARTCARD is also updated, therefore the SMARTCARD
becomes a copy of the drives stored configuration.
At power up, if Pr
11.42
is set to Auto (3), the drive will save the
complete parameter set to the SMARTCARD. The drive will display
‘cArd’ during this operation. This is done to ensure that if a user puts a
new SMARTCARD in during power down the new SMARTCARD will
have the correct data.
N
When Pr
11.42
is set to Auto (3) the setting of Pr
11.42
itself is saved to
the drive EEPROM but NOT to the SMARTCARD.
10.2.4 Booting up from the SMARTCARD on every
power up (Pr 11.42 = boot (4))
When Pr
11.42
is set to boot (4) the drive operates the same as Auto
mode except when the drive is powered-up. The parameters on the
SMARTCARD will be automatically transferred to the drive at power up if
the following are true:
•
A card is inserted in the drive
•
Parameter data block 1 exists on the card
•
The data in block 1 is type 1 to 5 (as defined in Pr
11.38
)
•
Pr
11.42
on the card set to boot (4)
The drive will display 'boot' during this operation. If the drive mode is
different from that on the card, the drive gives a 'C.Typ'. trip and the data
is not transferred.
If 'boot' mode is stored on the copying SMARTCARD this makes the
copying SMARTCARD the master device. This provides a very fast and
efficient way of re-programming a number of drives.
If data block 1 contains a bootable parameter set and data block 2
contains an Onboard PLC program (type 17 as defined in Pr
11.38
), then
the onboard PLC program will be transferred to the drive at power up
along with the parameter set in data block 1.
N
‘Boot’ mode is saved to the card, but when the card is read, the value of
Pr
11.42
is not transferred to the drive.
10.2.5 Booting up from the SMARTCARD on every
power up (Pr xx.00 = 2001)
It is possible to create a difference from default bootable file by setting
Pr
xx.00
to 2001 and resetting the drive. This type of file causes the
drive to behave in the same way at power-up as a file created with boot
