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.

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.
