In the main interface, click on the "Paramater" button, the screen to enter the
"Parameter setting" interface, as shown in the following figure:
In the "Parameter setting" interface,click on the "Ruturn" button, the system returns to
the main interface
Each parameter interpretation:
Y speed setting：

"Manual" means that the speed of hydraulic cylinder to move the manual operation
"Start" said hydraulic cylinder move start speed
"forward speed" indicates the maximum speed of the cylinder when the cylinder is
positioned forward
"forward creeping" means the speed of the cylinder after it has decelerated before
moving to the target position
"Backward speed" indicates the maximum speed of the cylinder when the cylinder is
positioned backwards
"Backward creeping" means the speed of the cylinder after it decelerates before
moving to the target position
“reference point” means the speed of the oil cylinder's return after automatic
processing is completed;
Action in advance:
“Forward deceleration ”indicates the displacement of the cylinder after
deceleration during the forward positioning of the cylinder during automatic
processing;
"Backward deceleration" indicates the displacement of the cylinder after decelerating
when the cylinder is positioned backward during automatic processing
"Forward precision" indicates the number of pulses sent by the deceleration system
of the cylinder during the forward positioning of the cylinder during automatic
processing;
"Backward precision" means the number of pulses sent by the deceleration system of
the cylinder when the cylinder is positioned backward during automatic processing;
The others:
Auxiliary wheel diameter: The roller that moves with the curved profile, the accuracy
of its diameter determines the dimensional accuracy of the profile position;
Zero time delay: the time for the spindle to rotate after the automatic processing is
completed and the setback position is reversed;
Fixed wheel spacing D0: the distance between the left and right shafts;
X zero distance: the distance from the photoelectric sensor switch to the left axis;

Forward soft limit: the amount of displacement from the Y axis to the forefront;
Retreat distance: After the automatic processing is completed, the distance that the
moving wheel shaft retracts from the starting position;
Retreat sync length: After the automatic processing is completed, the Y-axis moves
backward from the end position to the starting position, and the corresponding
distance the workpiece moves in the discharge direction.

Calculate the radius parameter "R" and the arc length parameter "L"
6, Rebound calculator
"Rebound calculator" function is to correct the error by circular arc profile of the
rebound coefficient modification,
because the profiles of different sizes, the hardness of the material is different, so the
rebound coefficient profiles are also different, in the actual production process, the

rebound coefficient profiles for increase of bending radius increases,
it is a linear relationship between the irregular.
The coefficient of restitution of the input is a empirical data, in the processing of the
first workpiece, processing of the arc can not achieve the desired size, this needs to
be calculated by the "Rebound calculator" features a new rebound coefficient, so that
the processing of arc is more close to the demand.

"Rebound calculator " interface, as shown in the following figure:
The methods used are as follows：
A、Fixed wheel radius RA: the minimum radius of the fixed shaft mold
B、Fixed wheel spacing: 350mm or other data
C、The target radius：The radius of the circular arc needed
D、The measurement radius ：the measurement data of the radius measuring
instrument
Enter the radius: Through the "Auxiliary calculation" to calculate the radius
E、Old parameter K0: rebound coefficient data In profile formula
The input is completed, click the "calculate" button, the system will automatically

calculate the new parameter K1, in profile formula interface, the parameter of K1 to
replace the old K0 parameters, click on the "conserve" button, and then enter to
automatic processing.
