What is Safety Analysis Recommendation?

You can choose between adjusting the speed only or adjusting the speed with the assumption of attaching a soft cover when applying the Safety Analysis Recommendation feature.

1-1. Speed Adjustment Safety Analysis Recommendation

Speed adjustment

This is the default setting for the Safety Analysis Recommendation feature. When analysis is performed with the Speed selected, deceleration and acceleration values are recommended for each segment of the uploaded robot motion or for the waypoints of the robot motion generated in SafetyDesigner.

1-2. Safety Analysis Recommendation with Soft Cover and Speed Adjustment

Speed adjustment & Soft cover

When Speed/Soft cover is selected, the analysis assumes the attachment of a soft cover to areas where the collision expected points or robot joints exceed the pressure limits specified in the standards. Additionally, it provides recommended robot speed values based on the state with the soft cover applied.

Speed/Soft cover – Set recommended points

The application of the soft cover is by default checked for all analysis points. However, in cases where there are specific application requirements (e.g., food processes sensitive to foreign material contamination) or when the end effector’s shape is complex (e.g., probing-type gripper corners) or the material prevents the attachment of the soft cover, even if the soft cover is recommended in the safety analysis results, it cannot actually be applied.

Therefore, the analysis is executed after excluding the collision expected points or robot joints where the soft cover cannot be attached from the checkboxes.

The following section explains the comparison between the results with speed adjustment and the results with both speed adjustment and soft cover applied.

In the analysis graph below, you can compare the results of analyzing the same 3D application without applying the Safety Analysis Recommendation feature and the results after applying the Safety Analysis Recommendation feature.

Comparison of Safety Analysis Recommendation – Before and after

Before applying the Safety Analysis Recommendation, the maximum CRI value exceeded the standard allowable limit at 1.5. After applying the feature, the maximum CRI value was adjusted to 1.

By accelerating in safer zones and decelerating in hazardous zones, safety was maintained while reducing the cycle time from 24 seconds to 20 seconds, resulting in improved productivity.

Additionally, detailed information about the attachment points of the soft cover applied during the Safety Analysis Recommendation, as well as the motion segments where speed adjustments are needed and their corresponding adjustment values, can be found in the layer window on the left side of the 3D screen.

Comparison of Analysis Results – Layer Window on the 3D Screen

There is a difference in the analysis recommendation results between the case where both speed adjustment and soft cover are applied, and the case where only speed adjustment is applied. As shown in the example above, when the risk calculated from pressure results in a higher value, the attachment of a soft cover provides a greater expected benefit than deceleration.

Compared to the analysis result with only speed adjustment applied, the state with the soft cover attached shows relatively higher acceleration recommendation values and lower deceleration values.
