[Cause]
There is an abnormality in the output of the sensor head.
[Countermeasure]
1 Check whether the load applied to the sensor head is too large. At this time, please move the robot and clear the load.
2 Reconnect power. If an alarm still occurs even after doing this, take the countermeasures in step 3.
3 This phenomenon may occur due to severe acceleration and deceleration. Reduce the weight of the tool installed on the force sensor and reduce the movement of the position when the alarm occurs Speed or acceleration.
4 When a grinder, automatic nut tightening device, etc. are installed on the robot, it may receive large external force from these devices. Consider whether it is possible to reduce the Rotation speed and other methods to reduce external forces.
5 Replace the sensor head.
