8.1 Action to Be Taken upon Occurrence of Problem
Upon occurrence of a problem, take an appropriate action according to the procedure below in
order to ensure quick recovery and prevent recurrence of the problem.
1) Status Display LED on Controller and PIO Check

ڏ z Automatic servo is OFF (Note 2) OFF ON
{ (OR)
In initializing process at power
being on
OFF OFF
2) Check whether an alarm occurs on the host controller (PLC, etc.).
3) Check the voltage of the main power supply (24V DC).
4) Check the voltage of power supply for the PIO (24V DC).
5) Check the voltage (24V DC) of the power supply for brake (For the actuator with the brake).
6) Alarm Check (Note1)
Check the alarm code on the teaching tool such as PC software.
7) Check the connectors for disconnection or connection error.
8) Check the cables for connection error, disconnection or pinching.
Before performing a continuity check, turn OFF the power (to prevent electric shocks) and
disconnect the cables of measuring instruments (to prevent accidental power connection
due to sneak current path).
9) Check the I/O signals.
Using the host controller (PLC, etc.) or a teaching tool such as PC software, check the
presence of inconsistency in I/O signal conditions.
10) Check the noise elimination measures (grounding, installation of surge killer, etc.).
11) Check the events leading to the occurrence of problem (Note 1) , as well as the operating
condition at the time of occurrence.
12) Analyze the cause.
13) Treatment
Note1: If parameter No.111 (Selection of using calendar function) is set to “1” (use), it is
possible to know the date and time at which the alarm occurred.
Set the date and time from the teaching tool such as PC software at the first
power-on of the controller.
The date and time data set once is retained for about 10 days if the power supply
of the controller is OFF. If the setting is not conducted or the time data is lost, it will
be the time passed since 0sec when the power is turned ON. Even if the date and
time data is lost, the generated error code is retained.
Alarms subject to this function only include those in 8.4 Alarm but do not include
errors in the teaching tool such as PC software.

In troubleshooting, exclude normal portions from suspicious targets to narrow down
the causes. Check 1) to 11) described above before contacting us.
