DANGER
When releasing the holding brakes, the robot
axes may move very quickly and sometimes
in unexpected ways!
Make sure no personnel is near or beneath
the robot arm!
If the robot is not connected to the controller,
power must be supplied to the connector
R1.MP.
The internal brake release unit is located at
the base of the robot and equipped with but-
tons for controlling the holding brakes for each
axis separately. The buttons are numbered
according to the numbers of the axes.
To release the brake on a particular robot axis,
push the corresponding button on the internal
brake release panel and keep it depressed.
The brake will function again as soon as the
button is released.
