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, drive unit, motor and external devices.
The "mode switch", "17-segment LED" and "axis display LED" used in the explanation
refer to the AD75 switches and LEDs.
