QUICK SIX
Software Sequence
Seq. # Description
1. Checks if amplifier is O.K.
Checks torques – forces STOP mode
Initializes unit/startup conditions of PLC
2. Channels open
Checks that the loading flag is in its home position (SQ7 ON).
3. Loading flag advances material for measuring
Detects and measures barstock using SQ1. If using long barstock, the
measuring will take place with the loading flag otherwise the pusher will
advance the barstock for measuring.
4. Loading flag advances past front of pusher
The loading flag advances 10mm past the front end of the pusher. This is to
ensure there is no barstock under the pusher support when it closes.
5. Loading flag retracts to its home position
Confirms that SQ7 is ON.
6. Pusher channel closes
Checks that channels are not still open (SQ3 OFF).
7. Confirms pusher support is closed
Confirms that the pusher support is closed (SQ4 ON).
Front two channels close according to the pusher position.
8. Advances barstock for measuring calculation
If using profiled material, the barstock is positioned to the back of the
clamping device. If loading a short barstock, the pusher will advance the bar
forward to be measured by SQ1.
9. Advances barstock to top-cut position
Barstock has been measured and proceeds to top-cut position. If using
profiled material the pecking cycle is activated.
10. Barstock in top-cut position
Top-cut position is achieved and is waiting for clamping device to close.
11. Production cycle
Channels open according to pusher position.
12. Pusher retracts to home position
The pusher retracts to its home position to initiate the new bar loading (SQ7
ON).
