Vibratory Track Screw Feeder FF/FM503H ver2
12
Caution: You can select only one type of screw feeding signal according to the specification.
If the hopper track driving motor continues swaying movement exceeding a preset time (2 minutes),
the machine enters into an intermittent operation mode with intervals preset by “Hopper track
intermittent running ON time setting (Pa.88)” and “Hopper track intermittent running OFF time
setting (Pa.89)”. If the swaying movement continues further, the machine enters into a suspend mode
assuming that there are no screws in the basket. In the suspend mode, “LED4 (=4 RUN)” LED on
the setup panel flashes at 1 second intervals. (Refer to
“10.1 Malfunction”.) To exit from the
suspend mode, turn on the machine again or input the screw feeding signal.

Caution: 1. Pa.8A and Pa.8B in the figure are operation parameter Nos. of the FF503H. Each of them can be
adjusted within the range of 0.5 to 10.0 seconds.
2. The escapement unit does not operate unless the operation enable signal is turned ON.
In order to prevent interference, perform screw taking-out with the external equipment with the
operation enable signal turned OFF to stop the escapement unit from operating.
3. To check the result of screw taking-out after taking out the screw with the external equipment,
check at the time shown in the figure above if the taking-out enable signal is OFF.
7. Instructions on adjustment of each part
Although the parts of the machine have been adjusted optimally at the factory before shipment, you can adjust
them again following the instructions described below. This chapter explains some major adjustment items.
After adjusting the following items, be sure to tighten the set screws and carefully check the operation before
starting to operate the part. The (Pa.**) in the instructions denotes a parameter number to be mentioned later
that allows setting change or adjustment. For details of parameter setting, refer to
“8. Setup procedures”.
