Appendix 4.2 Force Control Operation 

When the force control function is used, the force control button (F button) is displayed at the bottom of 

the JOG operation screen. 

Pressing this button displays the screen for the force control on the left side of the JOG screen. 
On the FORCE screen, specifying enable/disable of the force control, checking the current status, and 

monitoring the force sensor are possible. (When the F button is not displayed, check the parameter 
setting of "

Chapter4 4.4 (1) Robot number (AXMENO), axis number (AXJNO)

".) 

(1) Checking the force sensor data communication 

Display the force sense control screen of the teaching box and ensure that the force sensor data is 
displayed correctly. 
If the data does not change even when force is applied to the force sensor, the device connection or 
parameter settings is possibly incorrect. 

 

Ensure that the force sensor data changes.
