23-14 Maintenance Date and Time
Array [20]
Range: Function:
Size
related*
[ 0 -
0 ]
Set the date and time for next maintenance
occurrence if the preventive maintenance
event is based on date/time. Date format
depends on the setting in
parameter 0-71 Date Format while the time
format depends on the setting in
parameter 0-72 Time Format.
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.
In parameter 0-79 Clock Fault it is
possible to programme a warning if the
clock has not been set properly, for
example after a power-down.
The time set must be at least 1 hour
later than actual time!
NOTICE
When mounting an analog I/O MCB 109
option card, a battery back-up of the
date and time is included.
23-15 Reset Maintenance Word
Option: Function:
NOTICE
When messages are reset - maintenance
item, action and maintenance date/time are
not cancelled. Parameter 23-12 Maintenance
Time Base is set to [0] Disabled.
Set this parameter to [1] Do reset to reset the
maintenance word in parameter 16-96 Maintenance
Word and reset the message displayed in the LCP.
This parameter changes back to [0] Do not reset
when pressing [OK].

Array [6]
Range: Function:
The text is written according to the guidelines in
parameter 0-37 Display Text 1.
3.21.3 23-5* Energy Log
The frequency converter is continuously accumulating the
consumption of the motor controlled, based on the actual
power yielded by the frequency converter.
These data can be used for an energy log function
allowing the user to compare and structure the
information about the energy consumption related to time.
There are basically 2 functions:
•
Data related to a pre-programmed period,
dened by a set date and time for start.
•
Data related to a predened period back in time,
for example last 7 days within the pre-
programmed period.
For each of the above 2 functions, the data are stored in a
number of counters allowing for selecting time frame and
a split on hours, days, or weeks.
The period/split (resolution) can be set in
parameter 23-50 Energy Log Resolution.
The data is based on the value registered by the kWh
counter in the frequency converter. This counter value can
be read in parameter 15-02 kWh Counter containing the
accumulated value since the
rst power-up or latest reset
of the counter (parameter 15-06 Reset kWh Counter).
All data for the energy log is stored in counters, which can
be read from parameter 23-53 Energy Log.
