You can display the features on the servogun from the SETUP Servogun General screen.
The SETUP Servogun General screen displays the items in Table 1, " SETUP Servogun General Screen Items " .
Table 1. SETUP Servogun General Screen Items
ITEM | DESCRIPTION |
Tip Wear Comp |
This item specifies whether to perform tip wear compensation.
DISABLE = current tip wear measurement values are NOT applied as compensation to spot locations ENABLE = current tip wear measurement values are applied as compensation to spot locations. To use the tip wear compensation function, it is necessary to acquire a reference position and calculate a compensation value using TP programs. |
Gun Sag Compensation |
This item specifies whether to perform the spot gun
deflection compensation based on the Gun Sag amount for the pressure schedule
selected.
DISABLE = gun deflection compensation is not performed. ENABLE = the gun deflection compensation is performed. |
Close Direction (Gun) |
This item specifies the direction in which the movable tip is to be closed. |
Close Direction (Robot) |
This item specifies the tool coordinate system frame number and which axis of the tool coordinate system indicates the direction in which the stationary tip closes. |
Max Motor Torque (%) |
This item specifies a limit to the maximum torque of the servo gun motor in usual operation. The torque specified here is applied to the servo gun axis when pressurization is not taking place. Usually, the limit should not be adjusted by the user. The valid data range is between 1.0 and 10 |
Max Pressure (kgf) |
This item specifies a limit to the pressure to be applied during pressurization. Any pressure higher than specified here will not be generated. A similar limit is also placed during pressure input. This value should be specified by the gun manufacturer. |
Tip stick detect distance [mm] |
This item sets the tip opening after the weld complete signal to check the tip stick detection signal, if used. Set the tip stick detection signal in the weld I/O screen. |
Tip Wear Detection |
Items in this screen are used to specify how tip wear measurements are executed and how to process tip wear related alarms. |
Pressure Cal |
To display the Pressure Calibration screen, put the cursor on <*DETAIL*>, then press ENTER. This item specifies the motor torque to be generated, then measuring the pressure applied by the specified torque can yield a relational expression between the motor torque and pressure. When pressure adjustment is completed, the display changes from INCOMP to COMP. If the display remains at INCOMP, it is impossible to perform a spot welding sequence, manual welding, manual pressurization, and pressurization operation. |
Tip Wear Standrd |
This screen displays information about the status of tip wear compensation including data recorded during tip wear setup/initialization. When the reference positions are set, the display changes from INCOMP to COMP. |
Thickness Check |
This screen displays information about the setup of Part Thickness check. |
Gun Stroke Limit |
This screen displays the stroke limits for the gun axis. These limits are referenced from the master position, and more specifically, from the “reference zero position” when tip wear compensation is initialized. The stroke limits can be changed from this screen. |
Overtorque Protection |
This screen displays the Overtorque Protection status and settings. It is recommended to keep this function enabled to protect the gun axis from damage caused by the user jogging the tips to a high pressure. |
