Writing Parameter Values
These outputs are written from the adapter each time the User OUT point is
written from the network.
A value of zero in the Param# field disables the writing of data for that
specific point. Refer to the drive user manual for the desired parameter
number.

ATTENTION: Risk of equipment damage exists. If
configurable outputs are programmed to write parameter data to
Non-Volatile 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 configurable outputs to
write parameter data to NVS. Datalinks do not write to NVS and
should be used for frequently changed parameters.
TIP: Analog Data Integers (ADIs) are configured by first selecting
an Analog Output (AO) setpoint and then selecting the ADI.
