Basic key operation
Before checking the status of the I/O signals, set function code E52 to "2" (Full-menu mode).
(1) When the inverter is powered on, it automatically enters Running mode. In that mode, press the
key to switch to Programming mode. The function selection menu appears.
(2) With the menu displayed, use the
(3) Press the key to display the codes for the I/O check item list. (e.g.
(4) Use the and
The corresponding I/O check data appears. For control I/O signal terminal and control circuit
terminal input under communication control, use the
different display methods.
(5) Press the key to return to the I/O check item list. Press the
menu.

Displaying control I/O signal terminals

The status of control I/O signal terminals may be displayed with ON/OFF of the LED segment or in
hexadecimal display.
Display I/O signal status with ON/OFF of the LED segment
As shown in Table 3.13 and the figure below, each of the segments "a" to "e" on LED1 lights when
the corresponding digital input terminal ([FWD], [REV], [X1], [X2], or [X3]) is short-circuited with
terminal [CM] or [PLC]*, and does not light when it is open. Segment "a" on LED3 lights when the
circuit between output terminals [Y1] and [Y1E] is closed and does not light when the circuit is open.
Segment "a" on LED4 is for terminal [30ABC]. Segment "a" on LED4 lights when the circuit between
terminals [30C] and [30A] is short-circuited (ON) and does not light when it is open.
* Terminal [CM] if the jumper switch is set for SINK; terminal [PLC] if the jumper switch is set for SOURCE.
• If all terminal input signals are OFF (open), segment "g" on all of LEDs 1 to 4 will light
("– – – –").
• Refer to Chapter 5 "FUNCTION CODES" for details.
