Emergency stops
The configuration of emergency stops is stop category 1 and cannot be changed
when using RobotWare 7.1 or later.
Functional safety
The following safety functions are inherent design measures in the control system,
contributing to power and force limiting. They are category B, performance level
b, according to EN ISO 13849-1.

Description
The Cartesian speed of the elbow (arm check point, ACP) and
the wrist (wrist center point, WCP) are supervised. If a limit is
exceeded, the robot motion is stopped and a message dis-
played to the user. The default speed limit can be modified
based on the risk assessment of the robot installation.
The function is active in both manual and automatic mode. The
speed limits are set by system parameters. See Technical ref-
erence manual - System parameters.
Description
The FlexPendant is always equipped with a three-position en-
abling device, but for the IRB 14050 system the enabling device
is not used. Therefore the enabling device is disabled and in-
active when the FlexPendant is connected to an IRB 14050
system, but it is enabled and active when connected to another
robot.
In case of an unexpected mechanical disturbance, like a colli-
sion, the robot will stop and then slightly back off from its stop
position.
The robot system complies with the requirements of UL (Un-
derwriters Laboratories) for fire safety.
The robot system complies with the requirements of UL for
electrical safety.
