(9) 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.
(10) 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
An error is detected by the driver. Although this LED
flashes when the power limiter level is exceeded, this does
not indicate a problem as long as no 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.
(11) Encoder
connector This 15-pin, D-sub connector is used to connect the actuator’s encoder.
