6.2 AC servo driver inspection
Inspect the AC servo driver by following the steps below.
„
Only trained personnel should be allowed to perform the following operations.
Trained personnel are those who have taken a robot training course (held by
the dealer) or those who have carefully read the manuals and have equivalent
knowledge or skill.

Controller has the capacitors charged high voltage. To avoid an electric
shock, do not touch the dangerous high-voltage parts marked with the orange
label until the orange LED of motor power unit is faded out completely.
When the orange LED is faded out, the high-voltage capacitors are discharged.

Temperature of AC servo driver unit may rise depending on the operating
condition. Check the surface temperature before handling and use the pro-
tective gloves if necessary.
1) Turn OFF the controller and remove the front panel. (Do not disconnect the connec-
tors from the back of front panel.)
2) Check that the connectors attached to the AC servo driver units are securely attached.
If the connection is loose, reconnect it securely.
3) With the front panel off, turn the controller ON and execute the MOTOR ON command.
If the state of the LED lamps located on the front of the AC servo drivers is as shown
below, the AC servo drivers have no problem.
The green LED is lit.
The red LED is off.
If the green LED is off, power is not supplied to the AC servo driver. There are pos-
sibilities that power connector’s connection is not correct, or the AC servo driver’s
malfunction.
If the red LED is lit, control power supply (
±
5V, +24V) is improper. Find the part of
malfunction referring the section of PSU inspection, and eliminate the cause.
4) If the state of the LED lamps has no problem, execute the MOTOR ON command and
the motion command. If the robot moves properly, the inspection is now completed.
If an error occurs and the red LED on the AC servo driver turns ON when using the
MOTOR ON or motion command, refer to “15. Error Code Table” in this volume and
eliminate the cause of error.
