Displaying control I/O signal terminals
The status of control I/O signal terminal status may be displayed with ON/OFF of the LED segment
or in hexadecimal display.
I Display I/O signal status with ON/OFF of the LED Segment
As shown in Table 3.11 and the figure below, segments "a" to "e" on LED1 light when the digital
input terminals ([FWD], [REV], [X1], [X2], and [X3]) are short-circuited with terminal [CM] and do
not light when they are opened. Segment "a" on LED3 lights when the circuit between output ter-
minal [Y1] and terminal [Y1E] is closed and does not light when the circuit is open. LED4 is for
terminals [30A], [30B], [30C]. Segment "a" on LED4 lights when the circuit between terminals [30C]
and [30A] are short-circuited (ON) and dos not light when they are opened.
• If all terminal input signals are OFF (opened), segment "g" in all LEDs 1 to 4 will blink.
• Refer to Chapter 5 "FUNCTION CODES" for details.

nals. Refer to " Displaying control I/O signal ter-
minals " below for details on the display contents.
Shows the ON/OFF state for the digital I/O termi-
nals that received a command via RS485 commu-
nications. Refer to " Displaying control I/O signal
terminals " below for details on the display con-
tents.
Shows the input voltage on terminal [12] in volts
(V).
Shows the input current on terminal [C1] in milliam-
peres (mA).
