The following list identifies the significant risks integrators must consider.
Please note that there may be other significant dangers to certain robotic
devices.
Finger is sandwiched between the robot and the base (joint 1).
Finger is sandwiched between joints of the robot.
Sharp edges and sharp points on the tool or the tool connector may
cause damage to the skin.
Sharp edges and sharp spots on the obstacles near the robot’s
trajectory hurt the skin.
Consequences due to loosening of bolts used to secure robot or tools.
Items fall off the tool, for example due to insufficient clamping or
power down.
Operating error of emergency stop button on different machines.
2.4Safe operation
2.4.1 Emergency stop
Emergency stop, which takes precedence over all other robot control
operations, will cause all controlled hazards to stop, remove the motor power
from the robot drive, remain in effect until reset, and be reset only by manual
operation.
An emergency stop means the power system is disconnected and the arm can
not move. The user must perform a restoration procedure, resetting the
emergency stop button and pressing the "Power On" button on the pendant,
to resume normal operation. Emergency shutdown can not be used as a risk
reduction measure but can be used as a secondary protection device.
Configuration of the robot system as an emergency stop causes Category 0
downtime, stopping the robot immediately by de-energizing the motor and
releasing the brake.
Emergency stop must not be used for normal
program stop as this may result in additional
unnecessary wear on the robot.
