(8) Brake switch This alternate switch with lock is used to release the axis brake. To
operate the switch, pull it toward you and tilt.
Tilting the switch upward (RLS side) will release the brake forcibly, while
tilting it downward (NOM) will enable an automatic brake control by the
controller.
(9) Axis-driver status LEDs These LEDs monitor the operating status of the driver CPU that controls
the motor drive. The following three LEDs are provided.
Name Color Meaning when lit
ALM Orange
The driver is detecting an error.
This LED blinks when the current limiter setting
is exceeded. However, a blinking ALM LED
does not indicate a problem, unless an error is
present.
SVON Green The servo is on and the motor is being driven.
BAT ALM Orange
The voltage of the absolute-data backup
battery is low.
