6.3.3. Brakes
In case of brakes failure, each axis possibly drops with the motors [OFF]. Or, in
reverse, brakes possibly operate even with the motors [ON]. The latter causes
overload and noise.
When intending to operate the entire robot without the motors [ON], operate it with
the brake release switch [ON]. Before turning the switch [ON], take necessary
precautions to prevent the ARM from dropping as the robot ARM will drop by gravity.
.
Diagnostics
① Check if the brake can be heard in operation, by turning the brake release
switch [ON] [OFF] alternately with the motors[OFF]. If not heard, the vrake
cable may be broken. (When operating the brake release switch
[ON][OFF], be careful of ARM dropping. The brake release switch is
located on the panel in the controller cabinet door.)
Resolution
① If cables turn out to be good condition, replace the motor.
