7-2-6 Cumulative ON Time Monitor

■
Functions
• This function totals the time that one of the Inverter's control I/O terminals is ON by the second.
• For example, if the RUN output's ON time is totaled, it is possible to calculate the Inverter's operat-
ing time and monitor equipment operating time without using the ladder program.
• By measuring the total ON time of the input device connected to the input terminal, the re-
placement time of the input device can be determined.
• By measuring the total ON time of the output device connected to the output terminal, the re-
placement time of the output device can be determined.
• The total ON time for every I/O terminal can be measured, and a monitor value can be set for each
terminal.
• When the total ON time of the terminal reaches the monitor value or higher, the Connected Compo-
nent Maintenance Flag will turn ON in the Unit's Status Area.
Note 1. The input from the Inverter's control terminal block is ORed with the input from DeviceNet
communications, so the input is considered ON when either input source is ON. For exam-
ple, when either the RUN/STOP signal is input from the control terminal block or the input is
being received from DeviceNet communications, the corresponding multi-function input ter-
minal is considered as ON and the ON time is added.
Note 2. Either the cumulative ON time monitor or the contact operations monitor (refer to the follow-
ing function) can be set in each I/O terminal. Both functions cannot be set for the same ter-
minal.
Note 3. The total ON time is written to the EEPROM (in the DeviceNet Communications Unit or
Card) approximately every six minutes. Therefore, depending on the power OFF timing, up
to six minutes worth of data may be lost. To monitor more closely, click the Save Mainte-
nance Counter Button located on the General Tab Page of the Maintenance Information
Window immediately before turning OFF the power. The maintenance information including
the total ON time will be written to the EEPROM.
