4.4.2 Single module test
Whether the AD75 is operating correctly is confirmed with the LED displays on the
AD75 main body.
The "single module test" methods are described below.
The "single module test" can be carried out when there is no sequence program stored
in the PLC CPU, when there is no data stored in the AD75, and when the AD75 is
running.
Carry this test out after connecting the AD75, servo amplifier, servomotor and external
devices. The "mode switch", "17-segment LED" and "axis display LED" used in the
explanation refer to the AD75 switches and LEDs.
(Step 1) Turning ON the power
1) Stop the PLC CPU.
(When the AD75 is mounted on the remote station, stop the master station.)
2) Turn ON for the PLC CPU (when the AD75 is mounted on the remote
station, the mounted station and master station), and the power for the
servo amplifier and servomotor connected to the AD75.
3) The AD75 OS type [same displays as (Step 4)] will appear on the 17-
segment LED for one second.
4) After one second passes, the state will shift to the operation monitor 1
described in (Step 2).
(Step 2) Operation monitor 1
1) Depending on the AD75 state, one of the following will appear on the 17-
segment LED and axis display LED.
Confirm that the display matches the AD75 state.
AD75 state
17-segment
LED
Each axis' axis display LED (AX1 to 3)
Running RUN
The LED corresponding to the operating axis
flickers.
In test mode
TEST
The LEDs of all axes turn ON.
Idle IDL
OFF
Error occurrence
ERR
The LED corresponding to the axis in error
flickers.
2) When the mode switch is pressed, the state will shift to the operation
monitor 2 described in (Step 3).
