NOTICE
The frequency converter has no back-up
of the clock function and the set date/
time is reset to default (2000-01-01
00:00) after a power-down unless a real
time clock-module with back-up is
installed. Consequently, the logging is
stopped until date/time is readjusted in
parameter 0-70 Date and Time. In
parameter 0-79 Clock Fault it is possible
to programme a warning if in case the
clock has not been set properly, for
example after a power-down.
NOTICE
When mounting an analog I/O MCB 109
option card, a battery back-up of the
date and time is included.
Set the date and time at which the trending
starts the update of the timed bin counters.
Date format depends on setting in
parameter 0-71 Date Format, and time format
on setting in parameter 0-72 Time Format.

Set the minimum limit for each interval in
parameter 23-61 Continuous Bin Data and
parameter 23-62 Timed Bin Data. Example: If
selecting [1] counter and changing setting from
10% to 12%, [0] counter is based on the
interval 0–<12% and [1] counter on interval
12%–<20%.

3.21.5 23-8* Payback Counter
The frequency converter includes a feature which can give a rough calculation on payback in cases where the frequency
converter has been installed in an existing plant to ensure energy savings. Reference for the savings is a set value to
represent the average power yielded before the upgrade with variable speed control.
