OPERATION USING THE KEYPAD
3.4.5 Reading maintenance information “Maintenance Information: 5.CHE”
Menu number 5 “Maintenance Information: 5.CHE” contains information necessary for performing maintenance on
the inverter. The menu transition in “Maintenance Information” is same as that in Menu #3 “Drive Monitoring.” (Refer
to Section 3.4.3 .)
The monitor number and symbol are displayed alternately every 1 second.
Basic key operation
(1) Turn the inverter ON. It automatically enters Running mode in which you press the key to switch to
Programming mode. The function selection menu appears.
(2) Use the and keys to display “Maintenance Information” (
5.CHE
).
Press the key to skip in menu number units.
(3) Press the key to proceed to the list of maintenance items (e.g.,
5_00
).
(4) Use the and keys to display the desired maintenance item, then press the key.
The data of the corresponding maintenance item appears.
Press the key to skip to maintenance information +10. When the end is reached, the display returns to
