Displaying control I/O signal terminals under communications control
Under communications control, input commands (function code S06) sent via RS-485 or other optional communications can be
displayed in two ways: "with ON/OFF of each LED segment" and "in hexadecimal." The content to be displayed is basically the
same as that for the control I/O signal terminal status display; however, (XF), (XR), and (RST) are added as inputs. Note that
under communications control, the I/O display is in normal logic (using the original signals not inverted)
For details about input commands sent through the communications link, refer to the RS-485 Communication User's
Manual and the instruction manual of communication-related options as well.
Displaying control I/O signal terminals on options
The LED monitor can also show the signal status of the terminals on the optional digital input and output interface cards, just
like the signal status of the control circuit terminals.
Table 3.14 lists the assignment of digital I/O signals to the LED segments.

3.4.6 Reading maintenance information -- Menu #5 "Maintenance Information" --
Menu #5 "Maintenance Information" (
%che
) contains information necessary for performing maintenance on the inverter.
The menu transition in Menu #5 "Maintenance Information" is just like that in Menu #3 "Drive Monitoring." (Refer to Section
3.4.4.)
Basic key operation
To view the maintenance information, 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 "Maintenance Information" (
%che
).
(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.
(5) Press the
key to return to the list of maintenance items. Press the key again to return to the menu.
