NB!The frequency converter has no back up of theclock function and the set date/time will reset todefault (2000-01-01 00:00) after a power downunless a Real Time Clock module with back up isinstalled. Consequently the logging will be stop-ped until date/time is readjusted in par. 0-70,SetDate and Time. In par. 0-79,Clock Fault, it is pos-sible to program for a Warning in case clock nothas been set properly, e.g. after a power down.Hour of Day [0] , Day of Week [1] or Day of Month [2]. Thecounters contain the logging data from the programmed date/time for start (par. 23-51,Period Start) and the numbers ofhours/days as programmed for (par. 23-50,Energy Log Reso-lution). The logging will start on the date programmed in par.23-51,Period Start, and continue until one day/week/month hasgone.Last 24 Hours [5], Last 7 Days [6] or Last 5 Weeks [7]. Thecounters contain data for one day, one week or five weeks backin time and up to the actual time.The logging will start at the date programmed inPeriod Start,par. 23-51.In all cases the period split will refer to Operating Hours (timewhere frequency converter is powered up).23-51 Period StartRange: Function:2000-01-0100:00 *[2000-01-01 00:00 -2099-12-31 23:59 ]Set the date and time at which the Energy Log starts update ofthe counters. First data will be stored in counter [00] and startat the time/date programmed in this parameter.Date format will depend on setting in par. 0-71,Date Format,and time format on setting in par. 0-72,Time Format.23-52 Period StopRange: Function:2000-01-0100:00 *[2000-01-01 00:00 -2099-12-31 23:59]Set the date and time at which the Energy Log must stop up-dating the counters.If the period defined by par. 23-51 and 23-52 is longer than 24hours/7 days/31 days (depending on selection in par. 23-50),the logging will stop when all buffers are used.23-53 Energy LogRange: Function:[0] * 0-4294967295 Array with a number of elements equal to the number of coun-ters ([00]-[xx] below parameter number in display).
