1 3.1 3 BASIC OPERATIONS This chapter describes the basic operation of the KA counter. Explanatory Notes The explanations of operations in this chapter are organized in such a manner as shown below. Read this chapter with understanding of the way of explanation. Operation procedures described in this manual are mainly based on the case of using the 2-axis counter. Operation procedures unique to 1- or 3-axis counters are described when necessary. Q Operation example display No.
3.2 Basic Operations in the Standard Counter 3.2.1 Turning ON/OFF the power • Main power switch on the rear panel The switch on the rear panel is the main power switch. It turns ON/OFF of the main power to the counter. • Display ON/OFF switch on the front panel This is the switch to ON/OFF the counter display. The display will be on/off every time the switch is pressed.
3. BASIC OPERATIONS ● Where AT100 series is connected: 1) Turning the power on To turn the power on, turn on the main power switch on the rear panel. If this is the first time since setting up the KA counter, the display will blink. (This indicates that the displayed value is of no use.) By pressing the Cancel key, the counter is ready to display a normal count value. By referring to “3.2.3 Zero-set”, “3.2.4 Preset”, and “3.2.
● Where AT700 series is connected: 1) Turning the power on To turn the power on, turn on the main power switch on the rear panel. At this time, the display indicates the distance from the scale reference point. By referring to “3.2.3 Zero-set”, “3.2.4 Preset”, and “3.2.6 Setting the machine origin with the AT700 series”, set a machining datum point. 2) Turning the power off Use the display ON/FF switch on the front panel to turn the power off while remaining the main power switch on the rear panel on.
3. BASIC OPERATIONS 3.2.3 Switching the coordinate Moves from the current Coordinate to the specified coordinate. • Moves from the current Coordinate 3 to Coordinate 5. KA counter coordinate Coordinate No. Function 0 A coordinate system that displays coordinate values from the machine origin. It does not allow zero-setting and presetting. To use this function, perform either of “3.2.5 Saving and recalling a datum point using the scale reference point” or “3.2.
• Call up the value preset to preset it as is for the X-axis. • Canceling the key input before loading the preset value. If the Load key has not yet been pressed, it is possible to cancel all of the input numbers by pressing the Cancel key. After the numbers have been canceled, the display returns to the value before key input. If the Load key has already been pressed, use the preset operation again to set the correct value.
3. BASIC OPERATIONS NOTE If the following operations 1 and 2 are repeated at the occurrence of an overflow when using the AT100 series linear scale, an overflow error (Error30) may occur even if a value smaller than the maximum preset value shown below is preset. If presetting a large value and error occurrence are repeated multiple times, the above-mentioned situation will be encountered due to overflow of offsetting in the counter.
3.2.6 Saving and recalling a datum point using the scale reference point (when the AT100 series is connected.) Where the AT700 series is connected, refer to “3.2.6 Setting the machine origin with the AT700 series”. 1) Saving the scale reference point This operation saves the dimension between an appropriate reference point of the Linear Scale and the datum point of the workpiece being machined, in the KA counter as “origin data”.
3. BASIC OPERATIONS After the buzzer sounds off, the counter automatically returns to normal counting. IMPORTANT • When detecting the scale reference point move the worktable at a traveling speed of 50mm/s or less. If the worktable is moved faster than 50mm/s, the measuring error will increase. • When saving the scale reference point, be sure to remember the following two points. In order to recall the machining datum point, the same scale reference point that was saved must be used. 1.
If the axis was specified in the scale reference point recall operation, the saved origin data will be called up, however it is possible to key in a different value using the ten-key pad. TIP Step 2 Move the machine table and detect the same scale reference point that was saved by the scale reference point save operation. At the instant the reference point is detected, the KA counter starts counting. The machining datum point is recalled.
3. BASIC OPERATIONS 3.2.7 Setting the machine origin using the AT700 series With the AT700 series if the machine origin is once determined, that reference point cannot only be maintained through the subsequent normal operations such as zero setting, etc., but also be protected from being lost even when the power is off. Use the following procedure to set the machine origin offset value to Parameter 33. (1) Make sure that Parameter 33 is 0.000. 1.
2. Feed the table to align with the machine origin. 3. Record the displayed value. (3) Enter the machine origin offset value. 1. Turn off the power. 2. Substitute the machine origin offset value in Parameter 33. + In this substitution, note that the sign of the value recorded in above 3. of (2) must be reversed. 3-12 No.
3. BASIC OPERATIONS 3.2.8 Datum setting, centering and measuring with the touch signal probe (Possible only when the AT100 series is connected.) 1) Datum setting with the touch signal probe The KA counter can be connected to a touch signal probe (optional), and it is possible to set the datum point for a workpiece. • Setting up the datum point in the X-axis direction of the workpiece. Step 1 Preset the radius of the ball tip of the touch signal probe in the X-axis of the counter as shown below.
• Determine the center in the X-axis direction of the workpiece Step 1 Set up using keys so that the counter starts counting from zero in the X-axis at the time the touch signal probe comes into contact with the reference surface of the workpiece. (For centering, it is not necessary to correct for the radius of the probe ball tip.) Step 2 After setting us a function of holding the display move the touch signal probe to the opposite end, and bring it into contact.
3. BASIC OPERATIONS Step 3 With the Cancel key, release the Hold mode of the display, and move the machine table so the counter reads zero. Centering is now complete. IMPORTANT • Leave an interval of at least one second from the time the touch signal probe comes in contact with the workpiece until the next contact. If the interval is less than one second, it may be impossible for the counter to detect the measurement point. • Do not displace any axis scale during numeric entry.
Step 3 Before the touch signal probe is in contact with the measured surface on the other side, set up the Hold mode using the key. Step 4 Bring the touch signal probe in contact with the opposite end. The held display value is the dimension of the workpiece. Step 5 Quit the touch signal probe measurement function. IMPORTANT • When measuring with the touch signal probe move the worktable at a traveling speed of 50mm/s or less.
3. BASIC OPERATIONS 2) Halve the preset value for the X-axis. • Halve the preset value, 469.000. IMPORTANT • The value displayed at the time of the axis designation during the preset operation is the previous preset data. • The data entered with this operation is saved in the counter as preset data. 3.2.10 Bolt-hole circle machining This function is available exclusively with both 2- and 3-axis counters. (In case of using 3-axis counter, this function is available with X- and Y-axis settings.
The input range for the setting items are as follows: Setting item Input range Diameter ± 9999.999mm or ± 999.9999” Number of divisions 2 to 360 divisions Offset angle 0 to 359.9 degrees (unit: 0.1 degree) IMPORTANT • When using the bolt-hole circle machining function, the resolution for the X- and Y-axis should be the same. • If an error occurs in the KA counter, press the Cancel key to quit the bolt-hole circle mode.
3. BASIC OPERATIONS Step 4 While the “n” at the left end of the display is blinking, enter the number of divisions using the ten-key and press the Load key. If an auto-recalled value is used, only press the Load key. The KA counter display becomes ready for input of the offset angle. Step 5 While the “Ang” at the left end of the display is blinking, enter the offset angle using the ten-key and press the Load key. If an auto-recalled value is used, only press the Load key.
Step 7 After the hole has been made, press the Load key and call up the target value for the next hole, then move the machine table and drill the next hole. Each time the Load key is pressed, the target value is updated, so repeat the same procedure. Step 8 After machining the holes according to the set number of divisions, the counter returns to the display of the target value of the first hole.
3. BASIC OPERATIONS 3.2.11 Pitch machining This is the mode in which a certain interval between two points on the X-Y plane can be machined at even spaces. For this pitch machining the errors produced from positioning the table can be automatically corrected. Setup items and their ranges are shown below: • Setup item Input range X-axis start point ± 9999.999 mm Y-axis start point ± 9999.999 mm X-axis end point ± 9999.999 mm Y-axis end point ± 9999.
Step 3 Enter the Y coordinate of the start point. Step 4 Enter the X coordinate of the end point. Use the auto-recall value without modifying it. Step 5 Enter the Y coordinate of the end point. Use the auto-recall value without modifying it. Step 6 Enter the number of divisions. The maximum number of divisions is 999. Step 7 Perform the machining. 000 implies the completion of setting, while 010 shows implies the number of divisions.
3. BASIC OPERATIONS Feed the table so that the display shows 0.000. Even when a machining error is produced, it will never be accumulated because the error correction to the next target is automatically undertaken. Continue the machining while recalling the target values successively by pressing the LOAD key. Step 8 If the set numbers of the pitch machining is completed, the counter returns to the display of the first target value.
3.2.12 Zero approach machining If this function is used in the drilling process, the given pitch of the hole is entered in the counter and the target value from the current position to the hole is automatically displayed. The machine table is fed until the displayed value becomes zero, and the hole is drilled. By repeating this procedure, holes can be drilled efficiently. Errors involved in positioning the machine table are automatically corrected for the target value of the next hole.
3. BASIC OPERATIONS Step 5 Enter 12mm, the distance to the next machining point. The KA counter corrects the previous positioning error, -0.010mm and displays the actual distance the machine needs to move to reach the next machining point. Step 6 To quit the zero-approach machining function, press the Cancel key. IMPORTANT • Do not displace any axis scale during numeric entry. If displaced during entry for presetting, etc., the scale unit may be damaged due to an overrun.
3.2.14 Addition mode This function applies only to the 3-axis counter. By setting parameter 43, the KA counter will display the summed value of the Y- and Z-axis display values on the Y-axis display. (For information about parameter setup, refer to the appropriate parameter section.) An example of using the addition mode This mode is used if the feed table consists of two stages. If the addition mode has been set, “o” is displayed in the position of the most significant digit of the Z-axis display.
3. BASIC OPERATIONS - Restrictions when the addition mode is set Origin and touch signal setup operations If the addition mode is selected, the touch signal SET/HOLD and origin SET/HOLD functions on the Y- and Z-axis cannot be used. Example No. 1 ▼ [Y] The buzzer sounds twice. Example No. 2 [TSP] [HOLD] [Z] The buzzer sounds twice. The X-axis touch signal HOLD function can be used. Presetting • The presetting operation for only the Z-axis cannot be performed.
3.3 Outline of the Lathe Counter 3.3.1 Setting parameters for the lathe counter When this counter is used as the lathe counter, it is required to modify the initial values of parameters. For detail refer to “4.3.4 Setting parameters for the lathe counter”. Also for the method of turning on and off the power, refer to “3.2.1 Turning ON/OFF the power”. 3.3.2 Lathe counter operation modes The lathe counter operation modes in the KA counter are as illustrated below. 3-28 No.
3. BASIC OPERATIONS • Explanation of each operation mode is as mentioned below. No. Item Description 0 Power OFF The main power is turned off. 3 Count mode Counter basic mode in which machining operation is performed. 4 Display OFF mode Entered from the count mode with the [ON/OFF] key. Counting is still performed. 5 Parameter mode Parameters are input in this mode. 6 Origin recall Recalls the scale origin. 7 Origin storage Stores the scale origin.
Step 1 Check that the counter is set to the ABS coordinate in the count mode. If it is not set to the ABS coordinate, press the After confirming the display, press the key to switch to the ABS coordinate. key twice. (Press twice) “t” on the sub-display blinks to indicate that the counter is in the tool offset setup mode. NOTE If the current coordinate is the ABS coordinate, the decimal point in the sub-display is illuminating. For more information about the ABS coordinate, refer to “3.3.
3. BASIC OPERATIONS Step 3 Perform trial machining using the tool number 1. After moving the tool aside, measure the diameter of a workpiece with a caliper or a micrometer, then preset the measured value. Here, set 50.000 as the measured value. This completes the tool offset of tool number 1. Step 4 Switch the offset tool number to 2. Press the 2 key to select tool number 2. Tool number 2 will be displayed. Step 5 Perform trial machining using the tool number 2.
3.3.6 Zero-setting/Presetting The KA counter appends convenient capabilities to the zero-set and preset functions to facilitate lathe-machining operation. Zero-setting or presetting in the KA counter is performed not only for the currently displayed value, but also for the display values of other tools. Each reference point is parallel translated. If the tool No. 1 tip is on the workpiece surface as shown in the figure, the reference point of tool No.
3. BASIC OPERATIONS 3.3.8 A/I coordinate system switch The KA counter has two kinds of coordinate systems: Absolute (ABS) coordinate system, and Incremental (INC) coordinate system. • Change the coordinate system currently used. The coordinate system changes in the following order: ABS coordinate system INC coordinate system ABS coordinate system Illumination of the dot (.) in the sub-display shows they are ABS coordinates. No.
NOTE 1. Features of ABS and INC coordinates on the X-axis • The reference point in the ABS coordinate is designated as the center of a workpiece. Therefore, the display value in the ABS coordinate indicates the diameter of the workpiece. • In the INC coordinate zero-setting and presetting can be performed at an arbitrary position. For example, this function allows the real-time depth of cut to be displayed by zero-setting on a workpiece surface.
3. BASIC OPERATIONS 3.3.9 Halving the display The KA counter is capable of halving the display value or preset value and displaying the halved value. 1) Halve the display value for the X-axis. • Halve the currently displayed value, 100.000. NOTE Halving the displayed value on the ABS coordinate system cannot be performed. If the ABS coordinate is selected on the counter, select the INC coordinate using the key, then perform the halving operation. 2) Halve the preset value for the X-axis.
3.3.10 Zero approach machining If the pitch given on the design drawing is entered in the counter, the target value from the current position to the machining position is automatically displayed. Perform the machining until the displayed value becomes zero. By repeating this procedure, machining can be performed efficiently. Errors occurred in performing the machining are automatically corrected for the next NOTE target value. • Perform the machining on the Z-axis as shown below.
3. BASIC OPERATIONS Step 5 Enter 30mm, the distance to the next machining point. The KA counter corrects the previous positioning error, -0.005mm and displays the actual distance the machine needs to move to reach the next machining point. Feed the machine table to the machining position. Step 6 To quit the zero-approach machining function, press the Zero-approach key or the Cancel key. NOTE • It is recommended not to perform zero-approach machining on the X-axis.
3.3.11 Changing the unit of measurement It is possible to switch the unit of measurement between mm and inch (1/25.4). NOTE • The indicator “mm” on the front panel turns on if mm is selected. The indicator turns off if inch is selected. • When the display ON/OFF switch is turned on, the unit set when the switch was turned off will be displayed. 3.3.12 Saving and recalling a datum point using the scale reference point Refer to “3.2.5 Saving and recalling a datum point using the scale reference point”.

4.3.4 Parameters for the lathe counter mode When the KA counter is used as a lathe counter, it is necessary to modify the related parameters from their initial values. Set the required parameters while consulting with the table below. Parameter No.
4. PARAMETERS 4.3.5 Initializing the internal memory To restore the factory-set parameters, or when an error occurred in a parameter, it is necessary to initialize the internal memory. This restores factory-set initial values. Refer to sections 4.2.1 and 4.2.2 for the initial parameter settings. IMPORTANT When initializing the internal memory, be aware that the data (preset data, scale reference point data, bolt-hole circle data) in the KA counter memory is also initialized (initial value 0).
4.3.6 Display contents and parameters in the addition mode The display conditions of the Y-axis where the summed value (Y + Z) is displayed are as follows, depending on the parameter setup for the Y- and Z-axis. Error compensation (Parameters 12, 31) If the addition mode is set, do not use the error compensation function. Lower digit blank-out (Parameter 41) The erasure depends on the Y-axis setup for the number of lower digits to be blanked out.
1 5 MAINTENANCE This chapter describes measures to be taken against trouble with the counter and a guide to daily maintenance. Read this section carefully and take appropriate measures against problems. 5.1 Troubleshooting 5.1.1 Error messages The KA counter displays five kinds of error messages. When an error message is displayed, check the cause of the error before treating it. Error display Error20 Cause of error Treatment The table moved too fast and a Press the Cancel key.
If E20 occurs on the Z-axis If E20 occurs on the Y-axis E30 : If an overflow occurs on either the Y- or Z-axis, the counter display is the same as that for an E20 error. If the sum of the Y- and Z-axis values overflows, the counter displays E30 error and the b-segment on the most significant digits is not turned on. 5-2 No.
5. MAINTENANCE 5.1.3 Wrong key operation Event 5.1.4 Treatment The buzzer sounds twice. (Warning for invalid operation.) Perform the operation again correctly. Error when entering data with the ten-key. Cancel the operation using the Cancel key, and enter the data again. Troubleshooting Phenomenon Probable cause Inspection and treatment The power does not go on. • Poor power outlet connection. • Use a circuit tester to test the power cord for conductivity. If it is faulty, replace it.
5.2 Daily maintenance for the counter Wipe away any dirt or stains using a well-wrung, soft cloth that has been soaked in water. For stubborn stains, use a small amount of detergent. IMPORTANT • Absolutely do not use benzine, alcohol, thinner or a chemically treated cloth. They could discolor the panel on the counter. • Do not use an air gun to blow away dust. The dust could get inside the counter. • Some type of cutting oil may fuse the resin portion of this product.

6.4 Precautions for Using the Code Out Unit Precautions for data output via the RS-232C Code Out Unit of the KA counter that is connected to the AT700 series is shown below. ・ For ordinary data outputting (by using a command or touch signal probe), the KA counter does not use latch signals for sampling count values. For this reason, if a data request is made while the scale is traversing at a speed greater than 70 mm/s, incorrect data may be output.
