Releasing Brakes on UL-Listed Robot Units

The brake release operation on UL-Listed robot units is different from that on other
types. The UL-Listed robot units have the axis selector and the brake release switch on
the base for brake releasing.
NOTE: On robot units except UL-Listed ones, the teach pendant or mini-pendant is
used to release brakes. Refer to the SETTING-UP MANUAL, Chapter 5 "Commands
Assigned to Function Keys of the Teach Pendant" and Chapter 6 "Using the
Mini-Pendant."

Warning (1) Before pressing the brake release switch, make sure that
there is no danger that dropping the arm will cause bodily
injuries or equipment damage. Pressing the switch releases
the brake of the selected axis, dropping the arm depending
upon the axis.
(2) Do not turn the axis selector with the brake release switch
being pressed.
(3) To prevent an unintended brake release, usually set the axis
selector to OFF.
Turn the power switch of the robot controller to ON.
NOTE: Check that the motor ON lamps are not lit (motor power OFF).
Select the target axis to release its brake with the axis selector.
Press the brake release switch. Only when the switch is being pressed,
the brake of the selected axis is released.
