Appendix C: Stopping Time and Stopping Distance When Safeguard is Open
The stopping time and stopping distance when the safeguard is opened are shown in the graphs for each model.
The stopping time is the length of time corresponding to the "Stopping time" in the figure below. Be sure to confirm that a safe environment is provided where the robot will be installed and operated.
| Symbol | Description |
|---|---|
| a | Motor speed |
| b | Safeguard open |
| c | Time |
| d | Stopping time |
Conditions:
The stopping time and stopping distance depend on the parameters (setting values) that were set for the robot. These graphs show the times and distances for the following parameters.
- Accel: 100, 100
- Other settings: Default
Explanation of legend:
The graphs are displayed for each Weight setting value (at 100%, approx. 66%, and approx. 33% of the maximum payload, and at the rated payload).
- Horizontal axis: Arm speed (Speed setting)
- Vertical axis: Stopping time and stopping distance at each arm speed
- Time (sec): Stopping time (sec)
- Distance (deg): stopping distance (degree)
When single failures are taken into account, the following adjustments are used.
- Stopping distance and angle: Each axis reaches the mechanical stop
- Stopping time: Add 500 ms
