A steady yellow light comes on while the brake is released, and the LED is off while the
brake is actuated.
Description of STATUS indicators
What these indicators indicate varies depending on whether or not the servo is ON and an alarm is present.
(1) When the servo is ON
When the servo is ON, the STATUS LEDs on the front panel can be used to roughly monitor the motor current. The
command current ratios (percentage ranges of the rated current) and corresponding LED indicator statuses are shown
below.

(2) When the ALM signal is ON (an alarm is present)
When the ALM signal turns ON, the statuses of STATUS LEDs can be used to check the cause of the alarm. Since there
are only four LEDs, however, several causes are indicated by one indication pattern. Accordingly, you must connect the
PC software or teaching pendant to check the exact cause. Refer to “Alarm Indicator List” on the next page for the alarm
details, alarm codes and corresponding indicator statuses.
