Irrespective of the operation parameter setting “Screw feeding time setting (hand driver type) (Pa.41)”,
screws are fed while the screw feeding signal is being input from the external I/O receptacle.
To adjust the time, use an external control device, such as a PLC.
(2) For hand driver type
To adjust the screw feeding time, change the operation parameter “Screw feeding time setting (hand driver
type) (Pa.41)”. For how to change the parameter, refer to “8. Setup procedures”.
[1] For hand driver type (micro switch)
Such a contact is used for the screw driving signal that turns ON during screw tightening operation.
When this contact turns OFF
→
ON
→
OFF, the screw feeding starts and the screw feeding solenoid
valves and the track driving vibrator (to be more precise, Pa.41 + Pa.87 for the track driving vibrator)
operate for a preset time (Pa.41).
[2] For hand driver type (reed switch)
Such a contact is used for the screw driving signal that turns ON during screw tightening operation.
The screw feeding starts in a specific time (Pa.82) after this contact turns OFF
→
ON
→
OFF. The
screw feeding solenoid valve and the track driving vibrator (to be more precise, Pa.41 + Pa.87 for the
track driving vibrator) continue operations for a preset time (Pa.41).
7.4. Adjustment of screw feeding air flow rate
This adjusts the air flow rate at screw feeding operation. To adjust the flow rate, loosen the lock nut (as shown
in the figure below) and rotate the speed controller (4K type) or the screw feeding air flow rate adjustment
screw (4G type) according to the table below. The air flow rate is influenced by the screw size, air pressure,
screw feeding time, and screw feeding hose diameter. For this reason, after adjusting the air pressure, you need
to adjust the flow rate by actually feeding the screws. After the adjustment, be sure to tighten the lock nut.
CAUTION
Be careful! If the amount of air flow is too large, the screw may be removed from
the chuck unit and thrown away.
The screw thrown may cause an injury (You may lose your eyesight if it hits against your
eye), or damage to peripheral devices.
<Relation between adjustment methods and results>
Rotating direction of the speed controller or

Screw feeding air flow rate
Rotate to the right. (Tightening direction) Flow amount decreases. (Screw feeding time increases.)
Rotate to the left. (Loosening direction) Flow amount increases. (Screw feeding time decreases.)
