EE Memory Store This function takes the information in the Drive’s memory and places it in
the EEPROM. Any data in the EEPROM prior to issuing the EEPROM
STORE command will be erased.

NOTE: Word 4 of the BTR instruction is broken down into
two bytes. The High byte contains the status bits
per table 3.B. The low byte contains the Drive
message length in bytes.
Message Operation – The EE Memory Store function instructs the Drive
to replace the contents of the Drive EEPROM with the values that are
stored in Drive memory. Any configuration links present will also be
replaced by those in memory. Depending on the Drive firmware version,
this message may be ignored by the Drive when it is running (i.e. the
contactor is picked up).
ATTENTION: When using the EE Memory Store function you
must be certain that the values stored in Drive memory will not
degrade Drive or System performance and will not cause a loss
of either control or emergency stop functions.
This BTW function requires the message header only. The status byte in
the BTR will indicate the success or failure of the request.
