ModEva Pac Manual
Getting started with ModEva Pac Depending on software evolutions and the press brake controlled by the ModEva (configuration/capabilities), the present manual may not fully correspond to the ModEva that you currently have. However, differences are only minor.
Touchscreens are pressure sensitive. Do not press down hard on the screen. Pressing hard on the screen will damage the display. Such damage is not covered by manufacturer warranty!
Do not use sharp and/or pointed objects (sheet metal, screwdriver, metal pen ball, etc.) to touch the screen; only use your fingers (with or without gloves on) or a plastic pen. Make sure that your gloves do not have metal particles encrusted in the finger tips as they may also damage the screen. Take a few minutes to practice pressing gently on the screen, you will find that the screen is very reactive and it is pleasant to use.
Screen Cleaning
Turn off the ModEva to clean its screen. Use only a damp and smooth cloth with soap or a neutral detergent.
NEVER use solvent, petrol, benzene, alcohols, etc.

Bend Numerical Page (Direct Programming) → Bend Numerical
This type of programming is often used for simple products or by operators having worked on conventional press brakes without numerical controls. This page is very -friendly, for the operator has on one single screen all the information and fields necessary for the programming of his product.
The bending order is chosen by the operator, since he programs directly each bend. In this example, we will program the part described in Creating a Part Program (see page 15).
Setting Instructions: 1. Touch the
button and select New Product in the list.
2. On the top of the screen, select the material, enter its thickness and Sigma, and select the tools to be used for the part by touching their respective fields. 3. Program the required Angle (here 90.0°). The Y depth will be calculated according to the tools and the material already programmed. It is also possible to directly enter the Y1 / Y2 values without programming the angle. 4. Program the real position of the back gauge X1 (here 43.00). X2 can be individually modified if different from X1.
The programming of the real position of the back gauge requires of the operator to subtract (approximately) the steel thickness from the external dimension of the product. 5. If necessary, program the specific data for the current sequence (see Position of axes and other functions, page 23) 6. The two bends of section 1 (see Creating a Part Program, page 15) being identical, enter 2 in the CY field (CY stands for cycle, meaning this sequence is repeated twice in the program). button and select Copy 7. To create the subsequent sequence, press the Bend in the list. It can be seen that all the data has been copied into the second sequence. Feb. 22/34 2015 V2.0
ModEva Pac Manual
8. Proceed in the same manner as for section 1 to define lengths and angles values.
There is another way to program on this page, which has however some limitations depending on the product and the chosen bending order. It consists of entering the external flange dimension in the X field of the back gauge, and then programming a constant negative correction (see Bending, Tests and Corrections, page 24) corresponding to (approximately, according to your experience with the tools and the material) the material thickness.
Position of axes and other functions
The bottom section of the Bend Numerical page contains all the extra parameters for a bend. Some, like the bending force, are calculated automatically. But all these values can be modified by the operator.
→ Bend Numerical
According to his needs, the operator can modify the following items: • TDC, for Top Dead Center. If not programmed, the beam will rise to the maximum TDC. • Retraction BG, for the back gauge retraction. • Bending Length, defines the length of the part being bent, this parameter must already have been defined during the part programming phase. • SP, for Switch Point. The point where the beam switches from High Speed to Bending Speed. • Start Axes/AF, setting this parameter to External gives manual control over the back gauge movement. This means the operator must personally give the start to the back gauge movement, using for example the foot switch or the start button. • Crowning, if available, is automatically calculated. • Dwell Time, defines the amount of time during which the pressure is maintained. Feb. 2015 23/34 V2.0
ModEva Pac Manual
• Bending Speed, defines the downward bending speed and the upward moving speed from BDC to Pinch Point point. • Low Speed Distance, defines the portion (expressed in %) of the upward movement between the TDC and the Pinch Point which will be carried out at low speed; the continuation of the upward movement is made at high speed.
Complementary explications are found in the 2D Reference Manual.

ModEva Pac Manual
Getting started with ModEva Pac Depending on software evolutions and the press brake controlled by the ModEva (configuration/capabilities), the present manual may not fully correspond to the ModEva that you currently have. However, differences are only minor.
Touchscreens are pressure sensitive. Do not press down hard on the screen. Pressing hard on the screen will damage the display. Such damage is not covered by manufacturer warranty!
Do not use sharp and/or pointed objects (sheet metal, screwdriver, metal pen ball, etc.) to touch the screen; only use your fingers (with or without gloves on) or a plastic pen. Make sure that your gloves do not have metal particles encrusted in the finger tips as they may also damage the screen. Take a few minutes to practice pressing gently on the screen, you will find that the screen is very reactive and it is pleasant to use.
Screen Cleaning
Turn off the ModEva to clean its screen. Use only a damp and smooth cloth with soap or a neutral detergent.
NEVER use solvent, petrol, benzene, alcohols, etc.

Bend Numerical Page (Direct Programming) → Bend Numerical
This type of programming is often used for simple products or by operators having worked on conventional press brakes without numerical controls. This page is very -friendly, for the operator has on one single screen all the information and fields necessary for the programming of his product.
The bending order is chosen by the operator, since he programs directly each bend. In this example, we will program the part described in Creating a Part Program (see page 15).
Setting Instructions: 1. Touch the
button and select New Product in the list.
2. On the top of the screen, select the material, enter its thickness and Sigma, and select the tools to be used for the part by touching their respective fields. 3. Program the required Angle (here 90.0°). The Y depth will be calculated according to the tools and the material already programmed. It is also possible to directly enter the Y1 / Y2 values without programming the angle. 4. Program the real position of the back gauge X1 (here 43.00). X2 can be individually modified if different from X1.
The programming of the real position of the back gauge requires of the operator to subtract (approximately) the steel thickness from the external dimension of the product. 5. If necessary, program the specific data for the current sequence (see Position of axes and other functions, page 23) 6. The two bends of section 1 (see Creating a Part Program, page 15) being identical, enter 2 in the CY field (CY stands for cycle, meaning this sequence is repeated twice in the program). button and select Copy 7. To create the subsequent sequence, press the Bend in the list. It can be seen that all the data has been copied into the second sequence. Feb. 22/34 2015 V2.0
ModEva Pac Manual
8. Proceed in the same manner as for section 1 to define lengths and angles values.
There is another way to program on this page, which has however some limitations depending on the product and the chosen bending order. It consists of entering the external flange dimension in the X field of the back gauge, and then programming a constant negative correction (see Bending, Tests and Corrections, page 24) corresponding to (approximately, according to your experience with the tools and the material) the material thickness.
Position of axes and other functions
The bottom section of the Bend Numerical page contains all the extra parameters for a bend. Some, like the bending force, are calculated automatically. But all these values can be modified by the operator.
→ Bend Numerical
According to his needs, the operator can modify the following items: • TDC, for Top Dead Center. If not programmed, the beam will rise to the maximum TDC. • Retraction BG, for the back gauge retraction. • Bending Length, defines the length of the part being bent, this parameter must already have been defined during the part programming phase. • SP, for Switch Point. The point where the beam switches from High Speed to Bending Speed. • Start Axes/AF, setting this parameter to External gives manual control over the back gauge movement. This means the operator must personally give the start to the back gauge movement, using for example the foot switch or the start button. • Crowning, if available, is automatically calculated. • Dwell Time, defines the amount of time during which the pressure is maintained. Feb. 2015 23/34 V2.0
ModEva Pac Manual
• Bending Speed, defines the downward bending speed and the upward moving speed from BDC to Pinch Point point. • Low Speed Distance, defines the portion (expressed in %) of the upward movement between the TDC and the Pinch Point which will be carried out at low speed; the continuation of the upward movement is made at high speed.
Complementary explications are found in the 2D Reference Manual.
Bending, Tests and Corrections This chapter explains how to proceed in order to execute a product. This way of doing is destined only to demonstrate how to use the numerical control. The testing and adjusting operations can be carried out in the order decided by the operator.

8. Touch the Angle field, Bend column, and enter the measured angle (93.0 in this case). The software automatically calculates the necessary correction (-0.436, which can be seen in the Y1, Y2 fields, in the Bend column).
See also the Corrections section in the 2D Reference Manual. 9. Carry out a second test bend (on the same sequence, with a second test product). If necessary, make a new correction.
Depending on the material, the machine adjustment and the exactness of the data introduced, 2 or 3 corrections can be necessary for a bend. This can be considered as being a normal situation. 10.
