Check items and corrective actions for troubleshooting using the indicator LEDs
of the QD75 are described below.
(a) When the RUN LED turns off
Check item
Action
Is the power supplied?
Check that the voltage supplied to the power supply module
is within the rated range.
Is the power supply
capacity sufficient?
Calculate the total current consumption of the connected
modules (CPU module, I/O modules, and intelligent function
modules) and check that the power supply capacity is not
insufficient.
Is the module connected
correctly?
Check that the module is correctly connected to the base
unit.
If there is no problem on the above check items, a watchdog timer error
may have occurred. Reset the CPU module and check that the RUN LED
turns on.
If not, the possible cause is a hardware failure. Please consult your local
Mitsubishi service center or representative, explaining a detailed description
of the problem.
(b) When the ERR. LED turns on
Check item
Action
Is there a system error?
An error may have occurred in the CPU module. Check the
error and take a corrective action.
(c) When the ERR. LED and axis LED flash
Check item
Action
Is there an axis error?
Check the error code and take the action described in
Section 15.3.
(d) When all LEDs turn on
Reset the CPU module and check that the module is in the normal status.
If all LEDs still turn on, the possible cause is a hardware failure. Please
consult your local Mitsubishi service center or representative, explaining a
detailed description of the problem.
