7.1 Action to Be Taken upon Occurrence of Problem
Upon occurrence of a problem, take appropriate action according to the procedure below in order to ensure
speedy recovery and prevent recurrence of the problem.
a) Check the status indicator lamps.
Illuminating in green --- The servo is ON.
Illuminating in red --- An alarm is present or the motor drive power is cut off.
b) Check for error in the host controller.
c) Check the voltage of the main 24-VDC power supply.
d) Check for alarm.
Confirm the details of error on the PC or teaching pendant.
e) Check the cables for connection error, disconnection or pinching.
Before performing a continuity check, turn off the power (to prevent a runaway actuator) and disconnect the
cables (to prevent accidental power connection due to a sneak current path).
f) Check the I/O signals.
g) Check the noise elimination measures (grounding, installation of surge killer, etc.).
h) Review the events leading to the occurrence of problem, as well as the operating condition at the time of
occurrence.
i) Check the serial numbers of the actuator.
j) Analyze the cause.
k) Take action.
Please check items a) through i) before contacting IAI.
