Note Action
In the example below, with no arm
load and in synchronization posi-
tion, the pushing force from the
balancing device will cause the
lower and upper arm to move for-
wards/upwards, when the brakes
of the axis-2 motor are released.

DANGER
When releasing the holding brakes, the robot axes
may move very quickly and sometimes in unexpec-
ted ways.
Release of the axis-2 motor holding brakes can
cause the axis 2 to move in opposite direction in
regard to gravity, due to the pushing force from the
balancing device. Current arm load and position of
the lower and upper arm determines the occurring
movement when releasing the holding brakes of
the axis-2 motor.
Make sure no personnel is near or beneath the ro-
bot.
2
Release the holding brake on a particular robot
axis by pressing the corresponding button on the
internal brake release unit. 3
The brake will function again as soon as the button
is released.
Supplying power to connector R1.MP
If the robot is not connected to the controller, power must be supplied to connector
R1.MP on the robot, in order to enable the brake release buttons.
Note Action
DANGER
Incorrect connections, such as supplying
power to the wrong pin, may cause all
brakes to be released simultaneously!
