5.3.2.1.1. Multistep squeeze control

 

This function is to change the squeeze force being applied to the servo gun spot welding. There are two ways to change the squeeze force. The first one is by generating a predefined profile, and the second one is by changing it by inputting a signal.

                                                                                                         

 

 

(1)   Condition number

This displays the condition number for the multistep squeeze and auxiliary conditions.

 

(2)   Initial squeeze force

This displays the initial squeeze force set in the welding condition.

 

(3)   Squeeze force change

Select the method to change the squeeze force. Profile generation is a method in which the point of time and the duration of time for change are designated, and the squeeze force is changed at the relevant time. Signal input is a method in which the squeeze force is changed when a signal is inputted from an external device.

 

(4)   Handling when the status changes

If the status changes while in the multistep squeeze process or the waiting process, it will be decided whether to proceed after stopping the multistep squeeze process or to proceed after completing the multistep process.

 

(5)   <Profile generation>

This will be activated when the profile generation method is selected as the means of changing the squeeze force.

                     vii.        The point of time for change: Divide the spot steps into [Initial squeeze force reached] → [Welding execution output] → [Welding complete input], and designate the point of time to start the multi-squeeze process.

                    viii.       Duration of time for change: Once the point of time for change is reached, the squeeze force will be changed after the duration of time for change.

                      ix.       Squeeze force: Squeeze force targeted after the change

 

(6)   <Signal input>

This will be activated when the signal input method is selected as the means of changing the squeeze force. It is required to input the necessary information to communicate with external devices.

                       x.        Communication range: The minimum to maximum range of the assigned signal

                      xi.        Value range: The minimum and maximum values of the assigned signal

                     xii.        Squeeze force port: The number of the signal assigned for input

                    xiii.        Port assignment: The count of bits assigned to the signal

                   xiv.        Change request: Input the signal port for the change request.

                    xv.        Delay time: Input the delay time, if necessary, after inputting the request.

                   xvi.       Squeeze force: Squeeze force for the change request. It can be designated or inputted as a signal. The squeeze force received through a signal input will be ignored when the squeeze force is designated.
