(3) Place the feeder on the lower rail (feeders can be placed touching each other).

(4) Tighten the Allen screw until snug (do not overtighten).

(5) In the System Setup Interface (on any of the four screens), press the Modify Feed ID button.

Using the menus, change Feeder ID 50 to the desired ID. The interface should report that the ID was

successfully changed.

(6) If the interface reports that the change failed, check for the following:

(7) Feeder is not plugged in correctly.

(8) Feeder ID was not set to 50 when installed. Proceed to the Feeder Configuration page, and test

various feeder IDs to activate the feeder. If the feeder was installed so that it inadvertently shares an

ID with another feeder, both will activate.

(9) If the feeder has a unique ID other than 50, change it to the desired value.

(10) If the feeder shares an ID, unplug one of the feeders. This will enable the change of ID on a

single feeder.

(11) Once satisfied that the new feeder has been assigned the correct ID, go to the Feeder

Configuration page, and press “calibrate feeder”. The feeder should run continuously for several

seconds. Repeat this step to verify smooth operation of the feeder.

4.7.2 Physical installation of peelers:

Using a short 3mm Allen wrench, loosen the bolt in back of the peeler a few turns.

Plug the 2-pin connector into a numbered power port (the side of the connector with visible pin

detents faces up).

Place the peeler on the upper rail (peelers can be placed touching each other).

Line up the peeler so that it is parallel with the tape path in the feeder.

Tighten the Allen screw until snug (do not overtighten).

Go to the Peeler Configuration page, and press “Click to Test”. The peeler gears should turn, and

the peeler motor should be audible.

If both feeder and peeler tests are successful, proceed to the SMD Configuration page.

4.7.3 SMD configuration page

(1) This page contains the master configuration settings for the feeder/peeler combinations. Use this

page for the electric feeders (1- 48). It is not necessary for the special feeders (49-98). Following is

a description of the data displays and functions of the screen:

(2) For each feeder, the X-Y coordinates of the component location are listed. These coordinates

should be set by pressing the “Click to align” button to center the crosshairs in the pocket in the tape,

not necessarily the center of the component. This is because components shift significantly in the

tape, and any errors in component positioning can be corrected by the upward-looking camera

during pick and place operations.

(3) The “Feeder” and “Peeler” columns contain dropdown menus that allow the user to assign any

combination of feeder and peeler to serve as the numbered feeder indicated in the leftmost column.

By default, the Feeder and Peeler numbers are set to the same values.

(4) The “Click to test” button activates both the feeder and peeler assigned to the numbered feeder,

and each will advance according to the parameters defined in the Feeder Configuration and Peeler

Configuration pages.

4.7.4 Feeder configuration

Figure 4.25

Feeding Rate. For each feeder, this dropdown menu allows the user to set the distance in mm

that the feeder advances. For 0402 and 0201 components, this value is normally set at 2. For

components including 0603, 0805 and 1206, the value is normally set at 4. Certain larger

components will require larger values. See the Figure 4.25.

Strength. Determines the torque applied to the component tape. Values from 50-80 are common,

but the value should be adjusted so that the tape feeds consistently and smoothly.

Test. Clicking “Test” for any feeder on this screen will advance the feeder (but not the peeler)

by the distance set in the Feeding rate column.

Calibration. “Click to calibrate” advances the feeder continuously for several seconds. This

function verifies the smooth operation of the feeder motor and transmission. Because the feeder

advances quite far, it is best to avoid clicking this button when components are present in the feeder.

The button can be useful if needed to exhaust a long section of leader that contains no components.

4.7.5 Peeler configuration page

Figure 4.26

Function: Peeler configuration as above figure show, used to set the values for all peel boxes, see

the Figure 4.26.

Feeding rate: Similar meaning in Feeder, mean length of rotation each time. It determines the

approximate distance that the peeler will attempt to peel the cover tape. The default value for this

setting is 16, and there is often no need to reduce it the distance. The cover tape normally can slip

inside the moving gears of the peeler, and a larger peeling distance helps keep the cover tape taut

and out of the way of the components that have advanced into the pick position inside the feeder.

Strength: Torque setting of Peeler (Plastic tape will be difficult strip away in the case of being

affected with damp, can adjust bigger values of torque here). Smaller values (e.g. 50) result in

quieter operation, and are often adequate for smooth peeling.

Test: activates the peeler (but not its associated feeder). This function, when activated, should leave

the cover tape stretched tightly between the feeder and peeler, with no loose tape slop over the

components to be fed. If the cover tape does not advance when the peeler is activated, check the

installation. For proper operation, the tape must lie flat between the peeler gears; it must not be

wrinkled, stretched to deformity or twisted. The tape also must not be installed so that any part lies

outside the width of the gears. Tapes with long leaders make peeler installation much easier.
