EE Memory Initialize
This function initializes the Drive’s memory and EEPROM to a set of
default values stored internally in the Drive.
IMPORTANT: Any data in Drive memory and EEPROM prior to issuing
the EEPROM INITIALIZE 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–H. The low byte contains the Drive
message length in bytes.
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. This message is ignored by the Drive
when it is running (i.e. the contactor is picked up).
ATTENTION: When using the EE Memory Recall function
you must be certain that the default values stored in the Drive
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.
