A brake is mounted on the motor of Joints #3 and #4 of LS6 series to prevent the shaft
from moving down due to the weight of the end effector while the power to the Controller
is OFF or while the motor is in OFF status (MOTOR OFF).
Move the shaft down to its lower limit before the replacement procedure following the
removal steps.
For LS6 series
Joint #4 brake
Removal
(1)
Turn ON the Controller.
(2)
Push down the shaft to its lower limit while pressing the brake release switch. Be
sure to keep enough space and prevent the
end effector
hitting any peripheral

The brake release switch is applied to both Joint #3 and #4. When the brake release
switch is pressed, the
respective
brake for Joints #3 and #4 are released
simultaneously.
Be careful of the
shaft falling and rotating while the brake release switch is
being
pressed
because the shaft may be lowered by the weight of an end effector.
