Caution
8.1.2.7 Mode Switching Judgment Value
Sets the threshold used for switching between "speed priority mode" and "force priority mode" when the speed
command value is set for force sense control (force control).
The speed priority mode and force priority mode switch as follows based on the force command value and
switching judgment value, and force sensor data magnitude correlation.
Data Magnitude Correlation
Force Command Value and
Switching Judgment Value
Force command value >
switching judgment value
Force command value <
switching judgment value
Force command value =
switching judgment value
The speed specified with the speed command value is the force sense control offset
speed, and not the actual robot movement speed. If the robot is not moving in other
than in force sense control, such as when performing interpolation commands or JOG
operation, but moving only in speed priority mode, the "specified offset speed = robot
movement speed".
If interpolation commands or JOG operation are being performed in speed priority
mode, the "(specified offset speed + speed specified for interpolation, JOG operation)
= robot movement speed".
