[Trend Out 3]
Trend Out 3 displays the latest 500 trend input data
values once the trigger condition is true and all post
samples are gathered. This parameter is updated at
the same rate as the data was sampled. This
parameter can be linked to Analog Output (for
example) and a chart recorder connected to Analog
Output to provide a hard copy of the trend data.

484 Trend Input 4
[Trend In 4]
Trend In 4 specifies the data value to sample at the
specified trend sample rate. You should link Trend
In 4 to a source parameter (such as velocity, torque,
or current) for the trend to make sense.

➀ These values depend on the source parameter that this parameter is linked to.
For example, if the source parameter’s drive units are rpm, then Trend In 4’s drive
units will be displayed in rpm. The minimum and maximum values are also link
dependent.
