23 Technical Information Useful functions of counter units LT1A/LT11A/LT3 The combination of a high-accuracy digital gauge and an LT-series multifunction counter allows the following measurements to be made. The internal counter always holds current value, maximum value, minimum value, and peak-to-peak value irrespective of the measuring mode (current, maximum, minimum, and peak-to-peak values). Latch function The latch function holds output data and go/no-go judgment output with respect to its value in the current value mode. Datum [Latch conditions] Start input signal is set as latch input in parameter setting. Current value mode Note: This function does not work if the measuring mode is in peak-value mode. When to are traced in the current-value measuring mode, current value is displayed at position. Here (at position ), if the measuring mode is changed to the maximum value, indication becomes as in. In the same way, if the measuring mode is changed to minimum value, indication becomes as in and when it is set to peak-to-peak value, indication becomes as in -. In this way, the measuring mode is Latch ON Latch OFF Current value switched through the BCD terminal for models with BCD output or switched externally using command to display and output data. Datum-point reproduction function using a DK Series digital gauge and LT3 Series counter Up to now, even when master (datum point) calibration is made, the current position is reset if power supply is turned OFF. Thus, master (datum point) calibration needs to be made again using the master (datum point) at power ON. The DK Series Digital Gauges incorporate the reference point; once master (datum point) calibration is made, the counter can store data and reproduce the datum point without master (datum point) calibration in the reference-point referring function. First, a difference value between a digital gauge s built-in reference point and master (datum point) is measured to preset the master (datum point). If the master (datum point) is (zero), a difference value is preset to (zero). * The reference point is at the position where the spindle is pushed by 1 mm or more. When the counter s power supply is turned ON again, the counter starts up in the reference-point referring mode and display blinks in, causing the counter to enter reference-point detection waiting status. When the spindle is pushed and passes through the reference point, counting is made by the current value display from the master (datum point) position. (The counter stores internally a difference value between the master (datum point) and reference point in memory.) BCD output connector Using an LT Series as a multistage comparator For the LT Series counters, comparator settings are lower and upper limit settings as standard; no setting range can be increased. The LT Series BCD output specifications allow up to four sets of combinations of setting values (upper and lower limits) of the comparator to be registered. This allows an LT Series counter as a multistage comparator. Combining ON/OFF of pins 35 and 36 of the BCD output connector allows four ways (4 sets) of switching to be made. (Four sets of comparators can be set from 1st set (smallest range) to 4th set (largest range).) No. 35 pin No. 36 pin Upper and lower limits of comparator values H H Upper and lower limits of 1st set L H Upper and lower limits of 2nd set H L Upper and lower limits of 3rd set L L LED display Conditions High Go Low Measured data > upper limit Lower limit > measured data display display Count display blinking in After referencepoint detection (zero) setting by master calibration Higher than mater by 2 mm Count display blinking in (zero) setting by master calibration Higher than mater by 2 mm Combination (lower limit 1, upper limit 2) Combination (lower limit 1, upper limit 2) Combination (lower limit 2, upper limit 3) Combination (lower limit 2, upper limit 3) Combination (lower limit 3, upper limit 4) Combination (lower limit 3, upper limit 4) 2 Reference point Master (datum point) Workpiece 2 Reference point Workpiece Combination (lower limit 4, upper limit 5) Combination (lower limit 4, upper limit 5) Example 1: Case where the counter is used as a 6-stage comparator Example 2: Case where the counter is used as a 9-stage comparator In measurements where judgment output GO (OK) signal and In measurements where judgment output LO, GO, and HI signals and comparator combinations comparator combinations (4 sets) are observed in PLC I/O, four sets (4 sets) are observed in PLC I/O, if four sets of comparators are switched from the 1st set to the of comparators are switched from the 1st set to the 4th in turn and a 4th in turn and judgment output becomes high limit (HI), which judgment output (LO, GO, or HI) comparator for which judgment output becomes GO has an OK region. is produced in next combination is seen to determine which region applies. (If judgment output becomes GO in the 3rd set, the comparator (If judgment output becomes HI in the 2nd set and judgment output is LO in the 3rd set, an area concerned has the region of 3 mm or more to 4 mm inclusive.) of over 4 mm to 5 mm not inclusive applies.) 44 45
