9.17 Nozzle Protrusion Adjustment - Automatic
Adjustment
9.17.1 Calibrate the Carriage Home Position
WARNING
This procedure requires visual inspection of the machine while it is moving.
Wear eye protection.
The first time the E-Multi injection unit is installed, and any time it is
transferred to a new machine with a different mold, the carriage home
position and contact force must be set.
IMPORTANT
For proper calibration, ensure the nozzle protrusion is set correctly. See
“Nozzle Protrusion Adjustment - Toggle Link Models” on page 9-13 before
setting the home position.
9.17.2 Calibrate Manually
1. Put the E-Multi injection unit into Setup mode.
2. Navigate to the Reference Settings page. See the E-Multi Controller User
Manual for more information.
3. Move the carriage forward until the nozzle is just touching the manifold
inlet. This is the reference position as described in 9.16 on page 9-13.
4. Choose Set.
5. Press the [
F4
] button on the controller to increase nozzle contact force.
Continue pressing until the motor stops moving and the “Contact force
Set” display field stops increasing. At this point, the value in the display
field is the maximum contact force that can be generated with the current
setup.
6.
Use the “Contact force Set” entry field (the field to the right) to set the
desired nozzle contact force. A typical setting is 25-50% of the maximum
observed in the previous step.
7. Put the controller in Manual mode.
8. Use the [
F3
] button to move the nozzle away from the mold until there is a
gap.
9. Press and hold the [
F4
] button to move the nozzle towards the mold until
it stops. Verify that the contact force is equal to or slightly greater than the
set point chosen in step 6.
