Procedure 3)
In case the condition has not improved in Procedure 2, try to change the force control
transition threshold (Parameter No. 173).
When changing the setting, increase or decrease gradually
(Note 3)
referring to the following
conditions.
Condition 1 : When an overshoot is occurred to the pressing force, decrease the force control transition
threshold.
Condition 2 : When the stiffness of the work piece is low, increase the force control transition threshold.
Note 3 Increase or decrease the setting value in Parameter No. 173 by 5 to 10 (in the range between
10 to 90).
(3) Torque Level Detection during Pressing Operation (Valid in PIO pattern 6)
