KEYPAD FUNCTIONS
Basic key operation
To check the status of the I/O signals, set function code E52 to "2" (Full-menu mode) beforehand.
(1) Turn the inverter ON. It automatically enters Running mode. In that mode, press the
key to
switch to Programming mode. The function selection menu appears.
(2) Press the / key to display "I/O Checking" (
$i_o
).
(3) Press the
key to proceed to a list of I/O check items (e.g.
4_00
).
(4) Use the
and keys to select the desired I/O check item, then press the key.
The corresponding I/O check item data appears. For the item
4_00
or
4_01
, using the and
keys switches the display method between the segment display and the hexadecimal display (for I/O).
(Refer to Table 3.4-10 and Table 3.4-11.)
(5) Press the
key to return to the list of I/O check items. Press the key again to return to the
menu.
