The work data section controls the ram\u2019s top dead center (T.D.C.), bending force, hydraulic crowning, pinch point, mute point, bend time, speed, repetitions, and even special functions like pneumatic dies. If these parameters are not configured correctly, you may experience collision risks, inaccurate angles, excessive cycle times, or machine overload. In this guide, I\u2019ll explain every field in the ESA S650 work data \u2013 what each value means, how to adjust it, and when to use advanced options like C.S.T., Match, and Repetitions. By the end, you\u2019ll be able to set up a safe and efficient bending cycle for any job.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Understanding the Core Parameters of ESA S650 Work Data<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The work data section is where you fine\u2011tune the behavior of the ram and backgauge during each bend.\u00a0Correctly setting ESA S650 work data\u00a0starts with mastering these essential fields.\u00a0Every parameter in the ESA S650 work data\u00a0has a specific role in the bending cycle.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"936\" height=\"592\" src=\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20.png\" alt=\"ESA S650 Work Data\" class=\"wp-image-85211\" srcset=\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20.png 936w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-400x253.png 400w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-768x486.png 768w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-18x12.png 18w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-360x228.png 360w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-430x272.png 430w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-700x443.png 700w, https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/05\/image-20-150x95.png 150w\" sizes=\"(max-width: 936px) 100vw, 936px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">T.D.C. (Top Dead Center) \u2013 Safe Opening Height<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">T.D.C. defines how far the ram opens at the end of a bend (the space between the punch tip and the die edge).\u00a0When configuring ESA S650 work data, a higher T.D.C. makes it easier to remove and reposition the workpiece, but increases cycle time.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00.01 \u2013 999.99 mm\/inch<\/li>\n\n\n\n<li><strong>Empfehlung:<\/strong>\u00a0Set to at least the material thickness + 20 mm for safe clearance. For thick plates or complex parts, increase further.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Force \u2013 Bending Tonnage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the force required to bend the sheet metal.\u00a0Within ESA S650 work data, the control calculates an initial value based on material, thickness, and V\u2011die opening, but you can override it manually.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00.1 \u2013 9999.9 tons \/ short tons<\/li>\n\n\n\n<li><strong>Tipp:<\/strong>\u00a0If the angle is consistently over\u2011bent, reduce force slightly; if under\u2011bent, increase force. However, for precise angle control, use Y\u2011axis corrections instead of force changes.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Crown. (Hydraulic Crowning) \u2013 Compensating for Deflection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your press brake is equipped with hydraulic crowning, this field sets the percentage of maximum crowning force (0\u2013100%) needed to straighten the machine\u2019s base.\u00a0Correctly setting ESA S650 work data\u00a0for crowning ensures uniform angle across the entire workpiece length.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Standard:<\/strong>\u00a00 (no crowning)<\/li>\n\n\n\n<li><strong>Tuning:<\/strong>\u00a0Run a test bend on a long workpiece and measure the angle at both ends and the center. Increase the crowning percentage if the center angle is too open.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">C.S.T. (Change Step Time) \u2013 Delay Between Bends<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is a delay time (in seconds) between the completion of one bend and the movement of the backgauge for the next bend.\u00a0In ESA S650 work data, C.S.T. gives the operator time to remove or reposition the workpiece manually.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00 \u2013 99.99 seconds<\/li>\n\n\n\n<li><strong>Special value:<\/strong>\u00a099 means the machine waits indefinitely until the operator presses \u201cDown\u201d to continue. Use this for complex manual handling.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Pinch Point \u2013 Adjusting the Clamping Position<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The pinch point is the ram position where the workpiece is securely clamped before bending begins. This field adds an offset (positive or negative) to the calculated pinch point.\u00a0When you set ESA S650 work data, a positive pinch point value increases the clamping height, which can help avoid material slip.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a0-99.99 to 999.99 mm\/inch<\/li>\n\n\n\n<li><strong>When to adjust:<\/strong>\u00a0If the sheet slips during bending, increase the pinch point. If the punch hits the die too early, reduce it.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mute \u2013 Speed Change Point Offset<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The mute point is where the ram switches from fast approach to bending speed. This field offsets the calculated mute point. A positive value makes the speed change happen earlier (higher position), which can reduce cycle time but may increase collision risk.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a0-99.99 to 999.99 mm\/inch<\/li>\n\n\n\n<li><strong>Important:<\/strong>\u00a0The order must always be: T.D.C. > Mute > Pinch point > L.D.C. If you break this order, the program will not run in automatic mode.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Bend Time \u2013 Holding at Lower Dead Center<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The time (in seconds) that the ram remains at the lower dead center (L.D.C.) to allow the material to yield (especially for thick or springy materials). Longer bend time improves angle stability but increases cycle time.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00 \u2013 99.99 seconds<\/li>\n\n\n\n<li><strong>Use case:<\/strong>\u00a0For stainless steel or high\u2011strength materials, set 0.5\u20131 second. For soft aluminium, 0 is often sufficient.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Match \u2013 Controlled Rise Speed<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The speed (m\/min) at which the ram returns from L.D.C. to the pinch point after bending. A lower match speed prevents heavy plates from overturning toward the operator.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00 \u2013 10 m\/min<\/li>\n\n\n\n<li><strong>Empfehlung:<\/strong>\u00a0For thin sheets (\u22642 mm), use 5\u201310 m\/min. For heavy plates, reduce to 1\u20132 m\/min for safety.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Speed \u2013 Bending Ram Speed<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The speed at which the ram moves during the actual bending phase (from mute point to L.D.C.). Slower speeds give better angle accuracy, especially for air bending.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00 \u2013 10 m\/min<\/li>\n\n\n\n<li><strong>Tipp:<\/strong>\u00a0Start with 5 mm\/s and decrease if you see angle overshoot or vibration.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Advanced Work Data Functions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Functions 1 to 20 \u2013 Special Output Management<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These are ON\u2011OFF flags (0 or 1) that control external devices via the machine\u2019s I\/O. Function 2 is particularly important: when enabled, it manages pneumatic dies and folding bases, and allows the backgauge to move while the ram is still at T.D.C.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>To access functions not displayed:<\/strong>\u00a0Refer to the \u201cspecial functions\u201d chapter of your machine manual. You may need to scroll or use a secondary menu.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Rep. (Repetitions) \u2013 Repeat the Same Bend<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Number of times (1\u201399) that the current bend should be repeated before moving to the next bend. Useful for coining or when multiple hits are needed to achieve the final angle (e.g., large radius bumping).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Standard:<\/strong>\u00a01<\/li>\n\n\n\n<li><strong>Beispiel:<\/strong>\u00a0Set Rep.=3 for a coining operation where each hit closes the angle by 2 degrees.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Direct \u2013 Insertion Direction (Graphic Programs Only)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This field is not used in numeric programs. For graphic programs, it defines the direction of sheet insertion (forward or backward). Values: -1, 0, 1. Leave at default unless you have a specific workholding requirement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Ri (Internal Radius) \u2013 Calculated or Forced Radius<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Shows the calculated internal radius of the bend. In a numeric program, changing Ri directly influences the development (blank length) calculation. In a graphic program, it shows the operator what radius will be obtained.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Range:<\/strong>\u00a00 \u2013 9999.99 mm<\/li>\n\n\n\n<li><strong>Caution:<\/strong>\u00a0Modifying Ri in a numeric program will recalculate the stretch. Only do this if you know the exact radius from a test bend.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Step\u2011by\u2011Step \u2013 How to Correctly Set ESA S650 Work Data<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1 \u2013 Set Basic Safety Values<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>T.D.C.:<\/strong>\u00a0Material thickness + 20 mm (or more for deep boxes).<\/li>\n\n\n\n<li><strong>Gewalt:<\/strong>\u00a0Accept the calculated value initially.<\/li>\n\n\n\n<li><strong>Crown.:<\/strong>\u00a0Start at 0, adjust later if needed.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2 \u2013 Configure Cycle Timing<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>C.S.T.:<\/strong>\u00a00 for automatic feed; 2\u20133 seconds if manual handling is required.<\/li>\n\n\n\n<li><strong>Bend time:<\/strong>\u00a00 for thin materials; 0.5\u20131 second for thick or springy materials.<\/li>\n\n\n\n<li><strong>Match:<\/strong>\u00a05 m\/min for thin sheets, 1 m\/min for heavy plates.<\/li>\n\n\n\n<li><strong>Geschwindigkeit:<\/strong>\u00a05 mm\/s as a starting point.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3 \u2013 Fine\u2011Tune Ram Position Offsets<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pinch point:<\/strong>\u00a0Leave 0 unless material slips.<\/li>\n\n\n\n<li><strong>Stumm:<\/strong>\u00a0Leave 0. If you want faster cycles, increase slightly, but verify the order T.D.C. > Mute > Pinch point > L.D.C. still holds.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4 \u2013 Set Special Options if Needed<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Funktionen:<\/strong>\u00a0Enable Function 2 for pneumatic dies.<\/li>\n\n\n\n<li><strong>Repetitions:<\/strong>\u00a0Set >1 only for coining or bumping.<\/li>\n\n\n\n<li><strong>Ri:<\/strong>\u00a0Only modify in numeric programs if you have precise radius data.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5 \u2013 Test and Adjust<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Run a test bend.

By understanding the role of T.D.C., Force, Crowning, Pinch point, Mute, C.S.T., Bend time, Match, Speed, Repetitions, and special Functions, you can tailor the machine\u2019s behavior to the material and part geometry.\u00a0Mastering ESA S650 work data\u00a0allows you to start with conservative values and incrementally optimize after successful test bends. Remember the golden rule: T.D.C. > Mute > Pinch point > L.D.C. \u2013 breaking this order will stop automatic execution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now that you know how to correctly set\u00a0ESA S650 work data, I encourage you to open a simple numeric program and experiment with changing the Mute offset (e.g., +5 mm) and observe how the ram speed change point moves. Practice setting C.S.T. to 2 seconds to give yourself time to handle the sheet.\u00a0Correctly setting ESA S650 work data\u00a0will become second nature with a little practice.
