General Overview This manual will guide you through the installation, setup, and operation of the 100S GP system. Use it to get your system up and running “out of the box” and as a quick reference guide for your day-to-day operations.
General Preparation Packing List Verify that you have received all of the components for your system: • • • • Readout instructions Installation instructions Mounting arm ENC 125 scales - Cable mounting hardware - Scale mounting hardware • Warranty card If a component is missing, contact your 100S GP distributor immediately for replacement. Warranty Records Complete the warranty card included with your 100S GP system.
General Installing the Scales Please see the manual included with the scale for installation instructions. Installing the Readout Follow the readout installation instructions that are included with your mounting arm bracket kit. The electrical specifications for the readout are listed on pg. 25.
General Power Up Press the switch on the back of the readout to power up the system. A series of tests will check that the display, keypad, and memory are all working properly. If a problem is detected, an error code will appear on the screen. (Error messages and solutions are listed on pgs. 23 - 24.) It is important to note that the E1 message will appear every time you power up your system and does not indicate a problem. It merely indicates that the system had lost power.
Setup Parameter Setup These are the parameters that you can define on your system: • • • • • • Display resolution (diS) Linear error compensation (LEC) Scale resolution (rES) Scale count directions (Ct dir) Radius/Diameter (dIA) Position Recall (rECAll) Establish each setting the first time you power up the system. You can change the parameters later by returning to Setup and then using the ENTER key to scroll to the appropriate category.
Setup Display Resolution The display resolution determines how detailed each scale’s position will be displayed on the readout. Use the setting that best suits each job. To change the display resolution: • Press the SETUP key. (“diS” will show on the display.) • Press the AXIS key for the display you want to change. For 10µm scales, the display resolution will toggle between 0.01 mm (0.0005”) and 0.02 mm (0.001”). For 5µm scales, it will toggle between 0.005 mm (0.0002”) and 0.01 mm (0.0005”).
Setup Linear Error Compensation With 100S GP, you can compensate for machine tool wear. If you know the linear error compensation (LEC) value in parts-per-million (PPM), you can enter it directly. If you don’t know the LEC, use the formula on the next page to determine the value for each axis. To change the linear error compensation: • Move to the “Linear Error Compensation” display in the Setup mode. (Press SETUP and then the ENTER key until “LEC” (appears).
Setup How to Determine the Linear Error Compensation Follow this procedure for each axis: • In the DRO mode. • Place a standard of known length on the machine. Make sure it’s parallel with the axis being measured. • Put the readout in the absolute display mode (ABS/INCR key). • Using an indicator, locate one end of the standard. • Press the ZERO key twice for the axis you are measuring. “0” should appear on the display.
Setup Scale Resolution To ensure accurate readings, the scale resolution shown for each axis must correspond with the resolution of the scales on your machine. To change the scale resolution: • • • • If necessary, choose “Scale Resolution” from the Setup menu. (Press SETUP and then the ENTER key until the screen appears). Press the appropriate axis key (X, Y or Z) until the appropriate resolution appears. Choose 0.01 mm for 10µm (0.0005”) scales, 0.005 mm for 5µm (0.0002”) and 0.001 mm for 1µm (0.
Setup Radius/Diameter The Radius/Diameter parameter determines which axes will be effected by the RAD/DIA key. To change the Radius/Diameter mode: • Move until the display reads “DIA” in the Setup mode. (Press SETUP and then the ENTER key until “DIA” appears). “1” indicates the Diameter mode will be enabled. “0” indicates it will disable the Diameter mode. • Press the corresponding Axis key to enable or disable the Radius/Diameter mode. • Press ENTER key once you have chosen the correct mode.
Operation Power On Position Recovery With the 100S GP there are two means of position recovery, Position Recall and Reference Mark Evaluation. Position Recall When this feature is active (see setup parameters) the last displayed position is stored in memory when power is lost or turned off. When power is restored, the stored position is recalled and displayed. Note: Any movement that occurs while power is off will be lost.
Operation Reference Mark Evaluation ENC 125 encoders contain internal reference marks, approximately 4" apart along the length of the encoder. These marks enable you to easily re-locate your correct position after a power interruption. You relocate your position, relative to the last established datums, by traversing across one reference mark on each encoder.
Operation Setting the Datum (Absolute Zero) 100S GP allows you to measure both absolute and incremental dimen- sions. A dimension measured from the point you define as the datum is an absolute dimension. A dimension measured from any other point on your print is an incremental dimension. Datum, also known as absolute zero or workpiece zero, is the reference point from which 100S GP will base all of your part’s coordinates.
Operation To set the datum at the tool’s current position: • Touch the wheel to the edge of the workpiece. • Make sure the absolute position is displayed (ABS). • Press the ZERO key of the appropriate axis. Grinding wheel To set the datum using an offset: • Using the ABS/INCR key, select the absolute (ABS) mode. Also check that the proper measurement (inch or mm) is selected. • Using RAD/DIA key, select the Radius mode. • Move the tool to a known point, i.e.
Operation Incremental Dimensions As described earlier, incremental dimensions are measured from the current tool position. If your tool is currently at 2” and you want to move an additional 3.125”, you would select the incremental mode, zero out the axis, and move the axis until the display reads 3.125. An example of how to measure using incremental dimensions is shown on the next page.
Operation Example: Incremental Dimensions Absolute and Incremental Displays Absolute Display Shows the distance from your current position to absolute zero. Grinding wheel Absolute Zero, also called Datum or Workpiece Zero 1.625 X 1.625 ABS Incremental Display Shows the distance from your current position to incremental zero. An incremental zero is set when you preset a dimension or zero the incremental display. Grinding wheel Absolute Zero 3.250” 1.625” X -1.625 ABS The wheel is 1.
Operation Absolute and Incremental Presets To maintain the best tolerance and to minimize the chance for errors, use: • • absolute presets for absolute dimensions. incremental presets for incremental dimensions. Ensure tht the ABS or the INCR LED is lit accordingly. When you enter an absolute preset, it does not matter where the tool position is. The 100S GP calculates the desired location automatically. The display will show this. 2.44 1.44 ABS INCR X 0.72 . 7 2 ENTER X 1 .
Troubleshooting Troubleshooting Introduction Refer to this troubleshooting guide whenever you have questions or concerns about the operation of your 100S GP system. This guide is arranged in three columns entitled Symptom, Probable Cause and Recommended Corrective Action. The symptoms are listed in the order of the most common, easiest to check, and least expensive to correct. First locate the symptom that best describes the problem you are trying to solve.
Troubleshooting Symptom Probable Cause Screen is blank No power to the readout Recommended Corrective Action Check that the power switch on the back of the console is “on.” Check that the readout’s power cord is properly connected to the power supply Check the fuse. (Located below the power switch). Check that the power source meets the specifications required by your system (pg.25) LED failure Contact your 100S GP distributor for repair/replacement procedures.
Troubleshooting Recommended Corrective Action Symptom Probable Cause Dashes appear on screen Display overflow Move the axis toward the “0” position. As the scale counts down, the display will show the correct position. Error message (E1) appears Power loss occurred This is a normal message at power up. If the message appears at any other time during operation, a problem may have occurred. Refer to pg. 23 for details.
Troubleshooting Recommended Corrective Action Symptom Probable Cause Scale won’t count Loose cable Check that the scale cable is securely connected to the readout Wrong input Check that the scale cable is connected to the correct input on the back of the readout. Scale not installed properly Check the scale and reading head for proper installation (refer to scale installation instructions).
Troubleshooting Recommended Corrective Action Symptom Probable Cause Setup does not save values Improper procedure Press the ENTER key after each parameter value is entered. If you press another key instead, the new value may not be saved. Refer to pgs. 5 - 10 for proper procedures. Numbers don’t appear/ are faded on the display LED failure Turn the system “off” and then “on” again, using the switch on the back of the readout.
Troubleshooting Error Messages (General) When 100S GP is powered up, it will run a series of tests to ensure that the software is working properly. If an error message appears, refer to the charts below for a diagnosis and solution. E1 A power loss has occurred. This message will appear everytime you power up the system and can be cleared by pressing the CLEAR key. If the E1 message appears at any time other than at power up, a power interruption has occurred and your current position may be lost.
Troubleshooting Error Messages (Keypad Test) The messages below indicate that a problem was found during the keypad test at startup. If an error message appears, turn the system off, press the appropriate key to release it back into position, and then restart the system. (Or you can press the CLEAR key to clear the error message.) If the key does not work during normal operation, contact your distributor for repair/replacement procedures.
Reference Electrical Specifications Follow these specifications when installing your 100S GP system.
Reference Factory Default Settings 26 Display Resolution 0.0005”/0.01 mm (10µm) Linear Error 0 parts per million Scale Resolution 0.0005”/0.
Reference Keypad Here’s an overview of the 100S GP keypad. Each key’s function is described below. X, Y, Z (depending on how many axes are re Correspond with the scales on the X, Y,and Z-axes. Used to specify a change to a particular axis. ZERO These keys reset the incremental or absolute display position at “0” for the corresponding axis. ABS/INCR Used to switch between absolute (ABS) and incremental (INCR) measurements. The active mode will be displayed at the top of the DRO display.
Reference CLEAR Acts as backspace key during numeric entry; otherwise, it clears or cancels the last operation. ENTER Completes numeric operations; selects next parameter in SETUP. ± Changes the sign of the entered value from positive (+) to negative (-) or vice versa. Numbers are positive unless a (-) appears in front of them. . Decimal point can be used during numeric entry; also used to access the recall feature. 0-9 Used to enter a distance.
Reference Conventions This section identifies the standard conventions that apply to your 100S GP system. Count Direction 100S GP uses positive and negative numbers to determine the position of the table and tool on each axis. The graphic below shows a typical setup for the positive and negative count directions for the X-, Y-, and Zaxes. All of the examples in this manual are based upon this setup.
