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) Use
the and
keys 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 display the desired I/O check item, then press the
key.
The corresponding I/O check data appears. For the item
4_00
or
4_01
, using the
and
keys switches the display method between the segment display (for external signal information
in Table 3.17) and hexadecimal display (for I/O signal status in Table 3.18).
(5) Press
the key to return to a list of I/O check items. Press the
key again to return to the
menu.
Table 3.16 I/O Check Items
LED monitor
shows:
