15 – 1 PRELIMINARY OPERATIONS
– Start-up: refer to section 11.2.
– The type of numerical control and the date of the software program are displayed for a few
seconds (24). This display is followed by another, indicating the number of startups.
– The flashing entry START appears on the alphanumeric display device (item 31).
– One of the indicator lights up (inches or millimeters).
– Various segments appear on the displays (17 and 18).
– After this first operating phase, which takes place in a very brief time, the microprocessor is ready to carry out a first origin setting operation (X, V, R or Z).
– Press the flashing START key, (31) to start the origin setting. 
– When resetting is completed (beep), go into write mode by pressing the 
key (29).
– Display the adjustment values; hold down the 
key (11) for more than 2 seconds.
– The adjustment values are then displayed and can be modified. Check that they indeed correspond to the values shown on the inspection sheet that comes with your machine.
– Follow the procedure in section 15.4 to change the resetting values.
15 – 2 OPERATION
15 – 2 – 1 MANUAL MODE
– Press the 
key (30) to go into manual mode.
– Select the mm or inch unit by holding down 
(13) for 2 seconds.
– By pressing the
([ X ],[ Y ], [AUX]) (1, 2 or 3) keys, the alphanumeric display (24)
shows the entry MANUAL [ X ], MANUAL [ Y ] or [ A ] = nn.n.
a) MANUAL [ X ]:
– Pressing the [ X ] key (7) makes the X-axis move away from the bending axis.
– Pressing the [ – ] key (8) makes the X-axis move closer to the bending axis.
b) MANUAL [ Y ]:
– Pressing the [ + ] key (7) makes the distance between the punches and dies increase (pedal up, engaged).
– Pressing the [ – ] key (8) makes the distance between the punches and dies decrease (pedal up, engaged).
A short impulse on (7) or (8) results in a movement of 0.01 mm.
NOTE:
Simultaneous pressing of (7) or (8) and (6) results in high-speed rotation of the motor of the axes In question (X or Y).
c) A = nn.n
– Pressing the [ + ] key (7) makes the rear gauge stop lingers rise or separate (as
per R or Z configuration of gauge assembly).
– Pressing the [ – ] key (8) makes the rear gauge stop lingers descend or come
closer to each other.
When the values X, V, R or Z have been reached in accordance with the procedure below, the operator can carry out the bending operation.
15 – 2 – 2 PROGRAMMING
– Go into programming mode by pressing:
(29). All the display windows are empty, except for 19 (bend number) and 20 (program number set to 1).
– The indicator lights (27) light up in accordance with the last selection made (inches or millimeters).
– Select the program number (from 1 to 9) then press key [ P ] (9).
The amount of available memory is displayed (maximum of 81 steps). The program number selected is displayed on (20). The number of the first non-programmed bend is displayed on (19).
1 – ENTERING X-AXIS VALUE
– Enter the dimension on the numeric key-pad (26).
– Press [ X ] key (1); the value appears on the display (18).
2 – ENTERING Y-AXIS VALUE
– Enter the dimension on the numeric key-pad (26).
– Press [ Y ] key (2); the value appears on the display (17).
– A sound signal indicates and confirms that it has been stored in memory.
3 – ENTERING AUX-AXIS VALUE
– Enter the dimension on the numeric key-pad (26).
– Press [ AUX ] key (3); the value appears on the display (24).
4 – RELEASE OF PART
– Between two successive bends, it may prove necessary to provide a withdrawal on the X-axis, or simply a waiting time for this axis, before positioning a new part.
– After a bend has been made, the rear gauge assembly is locked for a time that can be programmed from 0 to 9 seconds.
– Program this time on numeric key-pad (26).
– Press 
key (4).
– The withdrawal time is then entered in memory.
_ Programming of a withdrawal time validates this value on the selected bend(s).
_ To cancel the withdrawal time programming, simultaneously press the 
and the key (4).
5 – CHANGING THE REAR GAUGE BLOCK WITHDRAWAL VALUE (IN PROGRAMMING MODE)
– Use the key (11) to call up the calibration values.
– Hold down (4) for two seconds to read the withdrawal values.
– Enter the selected dimension on the numeric key-pad (26) (0 to 600) and press (4).
For example:
– Gauge assembly value (X) = 100
– Required withdrawal = 50
– Enter 50 on the key-pad (26)
– The maximum withdrawal value must not exceed the capacity of the gauge assembly, i.e. 600 mm.
– Press the key (4) to validate,
– The gauge assembly moves back to 150 mm, awaits the program time “t” before positioning itself for the next bend.
6 – MACHINE FUNCTION
– Key [ M ] (5) is used to confirm an external all or nothing function (for example, a solenoid).
– This function can be associated to making the selected bend, within a given program.
– Type the number of the function on the numeric key-pad (26) (from 1 to 6).
– Then press the [ M ] key (5).
To cancel a machine function, type 0 on the numeric key-pad (26) and press [ M ] (5).
7 – PROGRAMMING OF NEXT BEND
– Press the [ N ] key (10); program the bend according to the same procedure used for bend number 1.
15 – 2 – 3 – RUNNING A PROGRAM
– Press the 0 key (29) to go into programming mode_ Type the number of the program you wish to use on the key-pad (25), then press the ~ key (9).
– Press ~ (10) to display 1 in window 19.
– Press 0 (28) to go into run mode.
– The START indicator light (31) lights up.
– Press START. The axes are positioned for bend number 1.
– Make the bend (see cycle selection heading in section 11.3).
– Each time the press starts to open, the axes are positioned for the next bend.
15 – 2 – 4 CORRECTION OF A BEND WITHIN A PROGRAM
Corrections may be made to the following parameters:
– Back position value (X).
– Penetration value (Y).
– Gauge assembly withdrawal value.
– Gauge assembly withdrawal delay.
– Machine function (auxiliary axis).
In all cases, press I’~ I (29) to go into programming mode.
1 – BACK POSITIONING OR PENETRATION VALUE
– Select the correction sign on the key-pad (26): <10 mm on X axis.
– Type in the correction value on the key-pad (26): <10 mm on the Y axis.
– Type ~ (1) or ~ (2), according to the axis selected.
2 – GAUGE ASSEMBLY WITHDRAWAL DELAY
The gauge assembly withdrawal delay consists of reprogramming with new value(s),
according to the procedure described in 15.2.2.
Warning: Only one withdrawal value per part can be selected for n bends.
3 – MACHINE FUNCTIONS (SEE 15.2.6)
4 – DELETING A BEND
– Enter the number of the bend to be deleted on the key-pad.
– Press ~ key (10) and hold down; press the 0 key (25).
– WAIT appears on the alpha-numeric display (24).
– Release the keys.
– A sound signal indicates cancellation.
– The numbering of the bends is automatically changed.
