Example Program of Force Sensor Compliance Control
A program example is shown below.
Program Example Description
- This program shows the example of a fitting operation.
- Force Sensor Compliance Control starts once the robot brings a workpiece to the starting position of the force control.
- The value of the force sensor will be reset (0N, 0Nm) when the force control starts.
- Force Sensor Compliance Control ends when the robot has moved the workpiece a predetermined distance.
