3.21.4 23-6* Trending
Trending is used to monitor a process variable over a
period of time and record how often the data fall into
each of 10 user-defined data ranges. This is a convenient
tool to obtain a quick overview indicating where to focus
on improvement of operation.
2 sets of data for trending can be created to make it
possible to compare current values for a selected operating
variable with data for a certain reference period, for the
same variable. This reference period can be pre-
programmed (
parameter 23-63 Timed Period Start
and
parameter 23-64 Timed Period Stop
). The 2 sets of data can
be read from
parameter 23-61 Continuous Bin Data
(current)
and
parameter 23-62 Timed Bin Data
(reference).
It is possible to create trending for following operation
variables:
•
Power
•
Current
•
Output frequency
•
Motor speed
The trending function includes 10 counters (forming a bin)
for each set of data containing the numbers of
registrations reflecting how often the operating variable is
within each of 10 pre-defined intervals. The sorting is
based on a relative value of the variable.
The relative value for the operating variable is
Actual/rated * 100%
for power and current, and
actual/max * 100%
for output frequency and motor speed.
The size of each interval can be adjusted individually, but
is 10% for each for default. Power and current can exceed
rated value, but those registrations are included in
90%-100% (MAX) counter.
