Message Operation – The EE Memory Recall function instructs the
Drive to replace the contents of Drive memory with the values that are
stored in EEPROM. Any configuration links present in the Drive will
also be replaced by those in EEPROM.
IMPORTANT: This message is ignored by the Drive when it is running
(i.e. the contactor is picked up).
This function requires the message header only. The status byte will
indicate the success or failure of the request.
