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 function requires the message header only. The status byte will
indicate the success or failure of the request.
