473 Trend Output 2
[Trend Out 2]
Trend Out 2 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.
Parameter Number 473
Parameter Type Read Only, Source
Display Units / Drive Units None
Factory Default 0
Minimum Value –32767
Maximum Value +32767
File – Group Diagnostics – Trend I/O
474 Trend Input 3
[Trend In 3]
Trend In 3 specifies the data value to sample at the
specified trend sample rate. You should link Trend
In 3 to a source parameter (such as velocity, torque,
or current) for the trend to make sense.
Parameter Number 474
Parameter Type Read/Write, Sink
Display Units / Drive Units Dependent on Link➀
Factory Default 0
Minimum Value –32767➀
Maximum Value +32767➀
File – Group Diagnostics – Trend I/O
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 3’s drive
units will be displayed in rpm. The minimum and maximum values are also link
dependent.
475 Trend 3 Operand Parameter X
[Tr3 Opnd Parm X]
Tr3 Opnd Parm X specifies the first of two parameter
numbers for the trend trigger evaluation. The data
value for the entered link parameter number is used
in the trigger evaluation.
Parameter Number 475
Parameter Type Read/Write, Sink
Display Units / Drive Units Dependent on Link➀
Factory Default 0
Minimum Value –32767➀
Maximum Value +32767➀
File – Group Diagnostics – Trend Setup
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 Tr3 Opnd Parm X’s
drive units will be displayed in rpm. The minimum and maximum values are also
link dependent.
476 Trend 3 Operand Parameter Y
[Tr3 Opnd Parm Y]
Tr3 Opnd Parm Y specifies the second of two
parameter numbers used for the trend trigger
evaluation. The data value for the entered link
parameter number is used in the trigger evaluation.
Parameter Number 476
Parameter Type Read/Write, Sink
Display Units / Drive Units Dependent on Link➀
Factory Default 0
Minimum Value –32767➀
Maximum Value +32767➀
File – Group Diagnostics – Trend Setup
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 Tr3 Opnd Parm Y’s
drive units will be displayed in rpm. The minimum and maximum values are also
link dependent.
