Location Pin Length
Specify the length in mm of any locating pins on the shape if they are present. This setting is especially required if using the insertion pressure function.
Specify the point on the leads (measured from the end of the lead) that is checked. If 0 is specified, the check occurs at the lead’s 30% position. The following settings represent general guidelines for various parts.
Quantity Check Limit
Specify the number of leads on leaded parts which must be detected for the part to pass inspection. If this is set to 100%, all the leads must be detected; if set to 90%, 90% of the leads must be detected. This is normally set to 100%.
This sets the brightness level for leads (bumps) that is used when automatic determination of lead brightness is difficult. Correspondingly larger values should be specified for brighter leads. When set to 0, brightness is determined automatically.
3. Process – Nozzle
Specify the minimum nozzle diameter which can be used to pick up the part with the shape.
Specify the maximum nozzle diameter which can be used to pick up the part with the shape.
Set this parameter for special nozzles. Although a nozzle is normally identified by the size of its circular pickup area, a name is specified for special non-circular nozzles.
4. Process – Pick
Do Auto Offset
Specify whether automatic compensation is performed for pick-up offsets. When No is specified, the center of the part is used as the part pick-up position. However, pick-up at the part center may not be possible for various reasons. To counter this, the amount of offset is calculated by vision processing and this information can be fed back to the pick-up position so that the part can be picked up at its center.
If parts are not being correctly picked up at their centers and “Do Auto Offset” is set to Yes, the offset between the nozzle center and the part center is calculated and fed back to the control software so that subsequent parts can be correctly picked at their centers.
Offset X, Y
Normally, parts are picked up at the center of their bodies. However, for some odd shaped parts this is not possible. If necessary, specify an offset from the center of the packaging cavity to the pickup point on the body for the part to pick-up such parts. If 0 is entered, the pickup point is the center of the packaging cavity. The value specified in Offset X, Y are the point at which the part is picked up, and the center of the camera field of view is aligned with the center of the nozzle during vision processing.
Specify an up or down offset for the pickup position of the part in a feeder cavity.
Tray Pick Offset Z
Specify an up or down offset for the pick-up point of the part in a tray cavity.
Soft Pick Speed
Specify the percentage of the maximum possible Z-axis speed at which the part is carried after pick-up.
Enable Pressure Sensor
This specifies whether or not the part using the shape data is picked with 220 gf when using the H01 head. If set to “Yes” the part is picked using pressure control, while if the setting is “No” the pressure control is not used when the part is picked. This setting is only applicable for the H01 head on the NXT. This setting has priority over soft pick-up settings.
Tolerance X / Tolerance Y
This sets the tolerance for misalignment of the nozzle center and part center. The machine rejects the part if these tolerances are exceeded.
Specify the tolerance for misalignments between the nozzle and part centers in the Q direction. Generally, 30 degrees is entered for Tolerance Q. For parts with a body dimension larger than 20 mm, input 15 degrees.
Specify the shuttle speed at which an MTU tray is loaded into the machine. A setting of 4 is the fastest speed, while a setting of 1 is the slowest.
Specify the acceleration/deceleration rate used when raising and lowering trays in the MTU.
5. Process – Place
Specify an offset value for part placement height.
Specify the force to be used to place a part using this shape when placed using a H01 head. The valid range for the NXT is 220 gf to 1020 gf. If “0” is specified here, the part is placed using no pressure control. When settings less than the minimum are specified, the part is placed using the minimum pressure. When settings more than maximum are specified, the part is placed using the maximum pressure. This setting is only applicable for H01 heads on the NXT. This setting has priority over soft placement settings.
Specify, as a percentage of the maximum transport speed, the speed at which the placing head carries the part from the pick-up position to the placing position.
Transport Speed Z
Specify the maximum speed at which the nozzle moves along the Z axis while transporting a part (i.e., from pickup to placement).
Transport Speed Q
Specify the maximum speed at which the nozzle rotates while transporting a part (I.e., from pickup to placement).
Soft Place Speed
This sets the Z-axis transport speed. This is the speed at which the part is lowered to the surface of the board. If this speed is too high, the part will spring back when the nozzle retracts, resulting in a misalignment.
Place Motion Selection (from NXT V3.10)
Specify the pressure (torque) method to be used for insertation pressure. This can be used with the H01 head. In order to use this function, Fuji Flexa V2.2.0 or higher must be used. The default setting of “0” disables this function. Enter a value between 1 to 4 to enable insertion pressure placing. If 5 is entered, insertion pressure is not used but if a claw is used to pick the part, the margin between the top of the part and the ledge on the claw will be 0 mm (normally there is a clearance of 0.5 mm).
Note: Always ensure to use backup pins underneath the panel when using insertion pressure.
Note: When an insertion error occurs and the user then clears the error, the machine determines that the part has been placed and proceeds to the next placement sequence when production is resumed. (Recovery is not performed)
Placing Thrust Pressure
Specify the force between 39.2 N to 98 N to be used to insert the part in newtons when insertion pressure is to be used (a setting of 1 to 4 is set for [Place Motion Selection]).
Placement Wait Time
Specify the time that the axis stops at the lower Z-axis limit for the placement. If a value shorter than the default time specified for the head type is specified, then the time specified in this setting is ignored and the time for the head type is used instead.
6. Process – Error
Alt Feeder Trigger
This setting is not used from the part data, but is set for the NXT through Accessory Software.
Specify the location where parts are dumped when an error occurs.
Forcing Recovery Times As 0 (from NXT V3.10)
Specify whether to force the number of recovery times to be zero (0) or to use the recovery times set in the shape/machine data. In order to use this function, Fuji Flexa V2.2.0 or higher must be used.
Specify the number of times a recovery is attempted when an error occurs. If no setting is specified here, the Recovery Count value in the configuration data is used.
