ATTENTION: Risk of equipment damage exists. If Explicit
Messages are programmed to write parameter data to Nonvolatile
Storage (NVS) frequently, the NVS will quickly exceed its life
cycle and cause the drive to malfunction. Do not create a program
that frequently uses Explicit Messages to write parameter data to
NVS. Datalinks do not write to NVS and should be used for
frequently changed parameters.
