3. Set a value to {GUN PUSHING COEF}.
– Set the value (0 to 10.0 [mm/1000N]) to the gun pushing coefficient
to compensate the registering position when press teaching is
performed.
– Press [SELECT] to input the numerical value.
4. Press [ENTER].
Calculation of Gun Pushing Coefficient
To {GUN PUSHING COEF}, set pushing amount [mm] per 1000N.
Fig. 1-2: Relation Between Pressure and Gun Axis Position [mm]
Following the relation mentioned above, calculate the change of gun axis
position per 1000N pressure and set it to {GUN PUSHING COEF}.
{GUN PUSHING COEF} is set with [mm] unit.
Pressure direction
