 Cumulative energy monitoring and resetting (Pr.170, Pr.891)
• During the monitoring of cumulative energy (Pr.52 = "25"), the monitored output power is added up. Its readout is refreshed
every 100 ms. (The values are saved in EEPROM every hour.)
• Increments and ranges of monitoring on the operation panel or parameter unit and via communication (RS-485
communication or other communication with communication option installed) are as follows.
On operation panel or parameter unit
Range
0 to 999.99 kWh
1000.0 to 9999.9 kWh
10000 to 99999 kWh
*1 Energy is measured in the range of 0 to 99999.99 kWh, and displayed in five digits. The cumulative energy up to 999.99 kWh is displayed in 0.01
increments such as "999.99", and that of 1000 kWh or more is displayed in 0.1 increments such as "1000.0".
• The digit of monitored value can be moved to the right by the number of Pr.891 Cumulative power monitor digit shifted
times. For example, when the cumulative energy is 1278.56 kWh and Pr.891 is set to "2", "12.78" is displayed (in 100's of
units) on the operation panel and the communication data is converted into "12".
• When Pr.891 = "0 to 4" and the cumulative energy reaches more than the upper limit of readout, the readout peaks out at
the upper limit, which indicates that moving digit is necessary. When Pr.891 = "9999" and the cumulative energy reaches
more than the upper limit of readout, cumulative value is reset to 0 and the metering restarts.
• Setting "0" in Pr.170 clears the cumulative energy value.
NOTE
• Once "0" is set in Pr.170, the setting of Pr.170 is turned to "9999" or "10" afterwards.
