5.4.4 Release device (optional)
Description The release device can be used to move the manipulator manually after an ac-
cident or malfunction. The release device can be used for the main axis drive
motors and, depending on the robot variant, also for the wrist axis drive mo-
tors. It is only for use in exceptional circumstances and emergencies (e.g. for
freeing people).
Procedure 1. Switch off the robot controller and secure it (e.g. with a padlock) to prevent
unauthorized persons from switching it on again.
2. Remove the protective cap from the motor.
3. Push the release device onto the corresponding motor and move the axis
in the desired direction.
The directions are indicated with arrows on the motors. It is necessary to
overcome the resistance of the mechanical motor brake and any other
loads acting on the axis.
5.4.5 Labeling on the industrial robot
All plates, labels, symbols and marks constitute safety-relevant parts of the in-
dustrial robot. They must not be modified or removed.
Labeling on the industrial robot consists of:
Rating plates
Warning labels
Safety symbols
Designation labels
Cable markings
Identification plates
5.5 Safety measures
5.5.1 General safety measures
The industrial robot may only be used in perfect technical condition in accord-
ance with its intended use and only by safety-conscious persons. Operator er-
rors can result in personal injury and damage to property.
It is important to be prepared for possible movements of the industrial robot
even after the robot controller has been switched off and locked. Incorrect in-
stallation (e.g. overload) or mechanical defects (e.g. brake defect) can cause
the manipulator or external axes to sag. If work is to be carried out on a
switched-off industrial robot, the manipulator and external axes must first be
Warning!
The motors reach temperatures during operation which can cause burns to
the skin. Contact should be avoided. Appropriate safety precautions must be
taken, e.g. protective gloves must be worn.
Warning!
Moving an axis with the release device can damage the motor brake. This
can result in personal injury and material damage. After using the release de-
vice, the affected motor must be exchanged.
Further information is contained in the technical data of the operating instruc-
tions or assembly instructions of the components of the industrial robot.
