(3) After the first screw reaches the escapement unit and when the screws that follow are aligned along
the track to the photoelectric sensor detection point, the hopper track stops swaying automatically.
4.6. Checking of screw feeding
After screws arrive at the escapement unit, the screw feeding solenoid valve is operated by the screw feeding
signal from the outside, and they are fed to the chuck unit of the driver unit by compressed air through the
screw feeding hose from the escapement unit. Attach a sensor to the screw feeding hose as necessary and
check if the screws are fed to the chuck unit correctly by compressed air. We have adjusted the screw feeding
to the specification. However, if a screw feeding failure happens, adjust the feeding. (Refer to “7.3
Adjustment of screw feeding time” and “7.4 Adjustment of screw feeding air flow rate”.)
5. Start of operation
5.1. For automatic type (Type:FF503H)
In sync with the screw tightening operation, input a screw feeding signal from an external control device, such
as a PLC, into the No. 7 pin of the FF/FM503H external I/O receptacle (CN IO). With this signal, the
FF/FM503H starts to feed screws by compressed air.
If you use the machine of this type, you need to set the type setting parameter (Pa.E1) to “Automatic type” in
advance. (For details of setup and adjustment mode, refer to “8.2.3 FF/FM503H Setup and adjustment
mode function list”.)
(Each machine is shipped from the factory with the parameters set in accordance with specified
specification.)
5.2. For hand driver type (Type:FM503H)
Connect the screw feeding signal cable of the hand driver tool to the screw feeding receptacle (CN FEED)
(hand driver type) of the FF/FM503H. When you tighten a screw with the hand driver tool (or when you
expand/contract the driver unit), the built-in switch of the driver unit is activated to input a screw feeding
signal to the FF/FM503H through the screw feeding receptacle (CN FEED) (hand driver type). With this signal,
the FF/FM503H starts to feed screws to the driver unit automatically.
IF you use this type, you need to set the type setting parameter (Pa.E1) to either “Hand driver type (micro
switch)” or “Hand driver type (reed switch)”. (For details of setup and adjustment mode, refer to “8.2.3
FF/FM503H Setup and adjustment mode function list”.)
(Each machine is shipped from the factory with the parameters set in accordance with specified
specification.)
5.3. For screw taking-out type
The escapement unit of the screw taking-out type differs in construction from that of the standard type; it is
equipped with a photoelectric sensor etc. in order to check whether there are screws in the taking-out position.
If you want to purchase the taking-out type, order the FF503H of taking-out type.
If you use this screw taking-out type, you need to set the type setting parameter (Pa.E1) to “Screw taking-out
type”. (For details of setup and adjustment mode, refer to “8.2.3 FF/FM503H Setup and adjustment mode
function list”.)
(Each machine is shipped from the factory with the parameters set in accordance with specified specification.)
