Configurator Settings
● Using the Maintenance Information Window
Click the OUT Tab or IN Tab in the Maintenance Information Window.
Note The differences between the OUT Tab Page and IN Tab Page in the Monitor Device Window
and in the Maintenance Information Window are as follows:
• The Maintenance Counter field shows the value when the maintenance information was re-
freshed and not the present value.
• The Clear Monitor Present Value Button is not included in this window.
• The maintenance counter can be saved (written to the EEPROM) by clicking the Save Main-
tenance Counter Button.
7-2-7 Contact Operations Monitor
Functions
■
• This function counts the number of times that one of the Inverter's control I/O terminals goes ON.
• The number of contact operations can be useful in maintenance, e.g., it can indicate when a con-
nected device needs to be replaced.
• The contact operations can be counted for each I/O terminal and a monitor value set for each termi-
nal.
• When the number of contact operations of the terminal reaches or exceeds the monitor value, the
Connected Component Maintenance Flag will turn ON in the Unit's Status Area.
Note 1. The terminal is considered ON when the ON time reaches or exceeds 20 ms.
Note 2. The input from the Inverter's control terminal block is ORed with the input from DeviceNet
communications. Therefore, for example, 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 terminal is considered as ON and the contact operation
is counted.
Note 3. Either the cumulative ON time monitor (refer to the previous function) or the contact opera-
tions monitor can be set for each I/O terminal. Both functions cannot be set for the same
terminal.
Note 4. The number of contact operations is written to the EEPROM (in the DeviceNet Communica-
tions 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 Maintenance Counter Button located on the General Tab Page of the Maintenance
Information Window immediately before turning OFF the power. The maintenance informa-
tion including the number of contact operations will be written to the EEPROM.
Application Example
■
The applications are the same as for the Cumulative ON Time Monitor (refer to the previous func-
tion).
