Universal Robots UR5e - Stop Categories

Using a plane to trigger the Reduced configuration: When the robot arm moves from the
side of the trigger plane configured with reduced safety parameters, to the side that is
configured with normal safety parameters, there is a 20mm area around the trigger plane
where both normal and reduced limits are allowed. This area around the trigger plane
prevents nuisance safety stops when the robot is exactly at the limit.
Using an input to trigger the Reduced configuration: When a safety input starts, or stops,
the reduced configuration, up to 500ms can elapse before the new limit values become
active. This can happen in either of the following circumstances:
•
Switching from the reduced configuration to normal
•
Switching from the normal configuration to reduced
The robot arm adapts to the new safety limits within the 500ms.
2.2.6. Modes
Recovery Mode
When a safety limit is exceeded, the safety system must be restarted. For example, if a
joint position limit is outside a safety limit, at start-up, Recovery is activated.
You cannot run programs for the robot when recovery is activated, but the robot arm can be
manually moved back within limits using Freedrive, or by using the Move tab in PolyScope.
(see Part II PolyScope Manual)
The safety limits of Recovery Mode are:
Safety Function Limit
Joint Speed Limit 30°/s
Speed Limit 250mm/s
Force Limit 100N
Momentum Limit 10kg m/s
Power Limit 80W
The safety system issues a Stop Category 0 if a violation of these limits appears.
WARNING
Failure to use caution when moving the robot arm in recovery can lead to
hazardous situations.
•
Use caution when moving the robot arm back within the limits, as
limits for the joint positions, the safety planes, and the tool/end
effector orientation are all disabled in recovery.
