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 3.12) and hexadecimal display (for I/O signal
status in Table 3.13).
(5) Press the
key to return to the list of I/O check items. Press the key again to return to the menu.
