Issue Number: 1

If the data is being transferred to the drive with different voltage or current rating a 'Card Rating' trip will occur. The following drive rating dependant

parameters RA coding bit set) will not be transferred to the destination drive from a NV Media Card when the voltage rating of the destination drive is

different from the source drive and the file is a parameter file. However, drive rating dependent parameters will be transferred if only the current rating

is different. If drive rating dependant parameters are not transferred to the destination drive they will contain their default values.

• Parameter Cloning (N01) = Read (1) - Reading from the NV Media Card

Setting Parameter Cloning (N01) modes to Read (1) and resetting the drive will transfer parameters from the NV Media Card to the drive parameters

and the drive EEPROM, i.e. this is equivalent to writing 6001 to Pr mm00. 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.

5.17.2 Auto saving drive parameter changes

• Parameter Cloning (N01) = Auto (3)

This setting causes the drive to automatically save any changes made to User Menu A parameters in the drive to the NV Media Card. If the NV Media

Card data block already contains information it is automatically overwritten.

Changing Parameter Cloning (N01) to Auto (3) and resetting the drive will immediately save the complete parameter set from the drive to the

NV Media Card. Once the whole parameter set is stored only the individual modified User Menu A parameter setting is updated. At power up,

if Parameter Cloning (N01) is set to Auto (3), the drive will save the complete parameter set to the NV Media Card.

Advanced parameter changes are only saved to the NV Media Card when Pr mm00 is set to 'Save Parameters' or 1000 and the drive reset.

If the NV Media Card is removed when Parameter Cloning (N01) is set to 3 Parameter Cloning (N01) is then automatically set to None (0).

When a new NV Media Card is installed Parameter Cloning (N01) must be set back to Auto (3) by the user and the drive reset so the complete

parameter set is rewritten to the new NV Media Card if auto mode is still required.

When Parameter Cloning (N01) is set to Auto (3) the setting of Parameter Cloning (N01) itself is saved to the drive EEPROM but not the NV Media

Card.

5.17.3 Boot from the NV Media Card on every power up

• Parameter Cloning (N01) = Boot (4) - Boot from NV Media Card on every power up

When Parameter Cloning (N01) is set to Boot (4) the drive operates the same as Auto mode, except when the drive is powered-up the parameters are

automatically transferred to the drive at power up if the following are true:

• An NV Media Card is inserted in the drive

• Parameter data block 1 exists on the NV Media Card

• The data in block 1 is type 1 to 4 as defined in Media Card File Type (N04)

• Parameter Cloning (N01) on the NV Media Card set to Boot (4)

The drive will display 'Booting Parameters during this operation. If the drive mode is different from that on the NV Media Card the drive gives a

'Card Drive Mode' trip and the data is not transferred.

If 'Boot' mode is stored on the copying NV Media Card this makes the copying NV Media Card the master device. This provides a very fast and

efficient way of re-programming a number of drives.

'Boot' mode is saved to the NV Media Card but when the NV Media Card is read, Parameter Cloning (N01) is not transferred to the drive.

• Pr mm00 = 2001

It is possible to create a bootable parameter data block by setting Pr mm00 to 2001 and carrying out a drive reset. This data block is created in one

operation and is not updated when further parameter changes are made. Setting Pr mm00 to 2001 will overwrite the data block 1 on the NV Media

Card if it already exists.

5.17.4 Comparing drive parameter set to NV Media Card

• 8yyy - Comparing drive parameter set to NV Media Card

Setting 8yyy in Pr mm00, will compare the NV Media Card file with the data in the drive. If the compare is successful Pr mm00 is simply set to 0. If the

compare fails a 'Card Compare' trip is initiated.

5.17.5 Erasing data from the NV Media Card

• 7yyy / 9999 - Erasing data from the NV Media Card

Data can be erased from the NV Media Card either one block at a time or all blocks in one go.

• Setting 7yyy in Pr mm00 will erase data block yyy

• Setting 9999 in Pr mm00 will erase all data blocks on a SMARTCARD. Note: It is not possible to erase all data blocks on an SD card. This must

be carried out using a PC and suitable adaptor.
