10 SD Card Operation
10.1
Introduction
The Non-Volatile Media Card feature enables simple configuration of
parameters, parameter back-up, storing / reading PLC programs and
drive copying using an SD card storing / reading PLC programs.
The SD Card can be used for:
•
Parameter copying between drives
•
Saving drive parameter sets
•
Saving an onboard user program
The SC Card slot is located at the middle of the module, adjacent to the
drive compact display (if installed) on the right-hand side.
Ensure the SD Card is inserted with the contacts facing the left-hand
side of the drive.
The drive only communicates with the SD Card when commanded to
read or write, meaning the card may be "hot swapped".

SD Card support
The SD Card can be used to store drive parameter sets and / or PLC
programs set from the Digitax HD in data blocks 001 to 499 on the card.
If the read only flag is set then only codes 6yyy or 9777 are effective.
Figure 10-2 Basic SD Card operation
The whole card may be protected from writing or erasing by setting the
read-only flag as detailed section 10.3.9
clearing the SD Card read only flag
The card should not be removed during data transfer, as the drive will
produce a trip. If this occurs then either the transfer should be
reattempted or in the case of a card to drive transfer, default parameters
should be loaded.
Beware of possible live terminals when installing the
SD Card.
