96M12219

CAUTION

■ Usage

• Be sure to turn off the power to the LS-7000 Series and any connected devices before connecting or disconnecting the cables. Otherwise, the camera and connected devices may be damaged.

• Do not turn off the power while setting a parameter. Otherwise, the settings may be partially or completely lost.

• Do not block the ventilation slots on the LS-7000 Series and peripheral devices. A rise in inner temperature may cause equipment failure.

■ Proper environment and conditions

To use the LS-7000 Series properly and safely, do not install the LS-7000 Series in locations with the following conditions. Use of this equipment in an improper environment may cause fire, electric shock, or equipment failure.

• Locations with high humidity, a large amount of dust, or poor ventilation

• Locations where the temperature rises excessively due to direct sunlight, etc.

• Locations where corrosive or flammable gas exists

• Locations where the LS-7000 Series is directly subjected to vibration or impact

• Locations where water, oil or chemicals may splash the LS7000 Series

• Locations where static electricity is easily built up

■ Countermeasures against Noise

The LS-7000 Series may malfunction or fail to operate due to noise generated from power lines or high-tension lines. If the LS7000 Series is operated close to such noise sources, use a noise filter, wire the cable of the LS-7000 Series in an independent conduit, or locate the LS-7000 Series in an area with proper insulation from noise.

Note: ■ Influence of Ambient Operating Temperature

Ensure that the ambient operating temperature is constant. A change in the ambient operating temperature may result in measurement errors. If the ambient operating temperature changes by 10°C, it will take approximately 60 minutes for the interior temperature distribution of the LS-7000 Series to be uniform.

■ Warming Up

Do not operate the LS-7000 Series for approximately 30 minutes after it is turned on. The internal circuitry of the LS-7000 Series is not stable immediately after it is turned on. The measured value drifts gradually as a result.

■ Influence of Dust and Dirt

A measurement error may result due to dirt, dust, water, or oil in any of the following cases.

• Cover glass: Blow off the dirt, dust, water or oil on the cover glass with clean air. If the cover glass is excessively dirty, wipe the glass with a soft cloth moistened with isopropyl alcohol.

• Target surface: Blow off the dirt, dust, water or oil on the surface with clean air or wipe the surface.

• Intrusion of dirt, dust, water or oil blown or sprayed into optical sensing area: Install a protection cover or perform air purging.

■ Influence of Vibration

The measured value of an object may fluctuate if the object is vibrating. If that happens, increase the averaging number. This will ensure highly accurate measurement.

■ Targets

The measured value of an object may have an error due to the shape and surface condition. Locate a reference object within the measuring area and use the calibration function of the LS-7000 Series to correct the error if that happens.

■ Influence of Air Flow

The measured value of an object may fluctuate due to a slow flow of air. In that case, the following countermeasures are effective.

• Protect the measuring head with a cover.

• Use a fan to mix the air vigorously between the transmitter and receiver.

■ Maintenance

Do not wipe the LS-7000 Series with a damp cloth or a cloth moistened with benzine or paint thinner. This may cause the discoloration or deformation of the LS-7000 Series. If the LS7000 Series is excessively dirty, use a tightly squeezed cloth moistened with thin neutral detergent. Then wipe the LS-7000 Series with a soft dry cloth.

■ Precautions for LED

The LS-7010/LS-7030/LS-7070 Measuring Head uses an LED light source. Abide by the following precautions when using the unit.

CAUTION

• Do not look at the LED light source for a long time. The LED used as the light source is classified into class 1 according to IEC60825-1 standards. Basically the light beam of the LED is safe, but do not look at the LED for a long time.

• Do not disassemble the unit. The unit does not incorporate a mechanism to stop the emission of the LED when the unit is disassembled. Never attempt to disassemble the unit, otherwise you will be exposed to LED light.

iii

Precautions for CE Markings

Keyence confirms that the LS-7000 Series meets EC directive requirements. The LS-7000 Series bears CE markings. Keep the following conditions if the LS-7000 Series is used in European countries.

Chapter 1 Getting Started

Outline and Features of LS-7000 Series

The LS-7000 Series is a high-speed, high-accuracy digital micrometer used for the dimensional measurement of objects without coming into contact with the objects. It is such a versatile model that it has a wide range of applications including in-line measurement and offline measurement.

■ Special Features

High-speed Sampling of 2400 Times per Second

Ensures high-speed sampling that is twice as fast as the sampling speed of conventional models. The continuous measurement of extruded products and the in-line measurement of moving workpieces are possible.

Repeat Accuracy of ±0.15

μm

Incorporates the latest optical system, thus ensuring excellent repeat accuracy that is twice as high as the accuracy of conventional models, thus supporting the manufacture of high-precision products.

Connecting Two Measuring Heads for two-channel Simultaneous Measurement

Two measuring heads can be used in combination for the simultaneous measurement of two targets.

Stable Detection of Transparent Objects with Threshold Change

The threshold change function supported by the DE processor makes it possible to detect transparent objects stably.

■ Principle of Measurement

The high-intensity GaN green LED radiates light, which will be changed into uniform parallel light through the special diffusion unit and collimator lens and emitted to the target in the measuring range. Then the shadow image of the target will appear on the HL-CCD (high-speed linear CCD) through the telecentric optical system. The output incident signal of the HL-CCD will be processed by the DE (digital edge-detection) processor in the controller and CPU. As a result, the dimensions of the target will be displayed and output.

Area Settings

Area settings are used to determine the measurements taken from a variety of objects placed in the beam. The LS-7000 Series can use up to two measuring heads to set two measurements (AREA1 and AREA2) for simultaneous measurements.

Area Settings

Area settings include the following items.

• Area: Select the measuring head number together with the DIA, T-EDGE, B-EDGE, or SEG mode.

• Focus monitor: A function to check whether the target is within the measuring range. Set the best measuring range (i.e., the distance between the target and transmitter) with this function.

• Area check: Set the total number of edges to be measured. If the number of edges detected does not coincide with the set value, the measured value will be invalidated.

• Difference check: If there is a radical change between measured values, the change will be detected and output. Set the value for the change to be detected.

• Function output selection: Set the items to be output from the output terminal on the rear panel.

• Edge detection threshold change: Set the threshold to be detected when measuring highly transparent objects.

Area

When a target is located in the measuring area as shown below, the light into the receiver is partly obstructed, thus creating a shadow. The contour of the shadow is called “edge.” The area is surrounded by the edge line. The LS-7000 Series can measure objects with area designation or edge designation. Area designation is possible in DIA, T-EDGE, or B-EDGE mode. Edge designation is possible in SEG mode.

Calibration Settings

The measured value of a target may have a subtle error due to the surface condition and angle of the target. Calibration settings correct for this error. It is possible to make calibration settings for each area independently.

■ Types of Calibration Settings

Select the type of calibration from the following ones in advance. Refer to Calibration Type Selection on page 4-23. Logic calibration: Logic calibration requires two types of master workpieces that are

different to each other in size. Calibration is performed according to pre-calibration and post-calibration values that are input by the user. This type of calibration is used for the measurement of the distance between two workpieces, for example.

Two-point calibration: Two-point calibration requires two types of master workpieces that

are different to each other in size.

One-point calibration: One-point calibration requires a single master workpiece. This

calibration is used for the size measurement of a single type of workpiece.

Logic Calibration/Two-point Calibration

Prepare target 1 (T1) and target 2 (T2) as two measuring points. The LS-7000 Series performs calibration on these points based on the T1-A and T2-A display values, which are obtained before calibration, and the T2B and T2-B display values, which are obtained after calibration. In this case, the non-calibrated display values are converted into the calibrated display values with the span value (inclination) and shift value of the workpiece determined by the LS-7000 Series internally.

One-point Calibration

Prepare target 1 (T1) as a single measuring point. The LS-7000 Series performs calibration on this point based on the display value before calibration and that after calibration. In this case, the non-calibrated display value is converted into the calibrated display value with the span (inclination) and shift value of the workpiece determined by the LS-7000 Series internally. The span value is always set to 1.

● Self-timing Hold and Area Settings

The LS-7000 Series in self-timing hold operation will detect a target when the target is within the optical axis. Then the LS-7000 Series will start sampling after a certain period (i.e., a self-timing period) elapses. Therefore, the target may enter the measuring area from any direction as shown below.

The LS-7000 Series will detect the target within the optical axis when the LS-7000 Series confirms a certain number of edges and not at the moment the target enters the optical axis. The confirmation condition varies with the measurement method selected as an area setting. Refer to the following examples.

Diameter (DIA) Measurement

The target will be detected when the number of edges in the optical axis is four or over.

Edge

1 2

3 4

The number of edges in the optical axis is two. The target has not been detected yet.

The number of edges in the optical axis is four or over. The target has been detected.

Segment (SEG) Measurement

The target will be detected when the number of edges in the optical axis coincides with the number of edges specified. In the following example, settings are made so that the width between edges 002 and 003 will be measured.

Edge

The specified edge value (003) has not been detected within the optical axis. The target has not been detected.

The specified edge value has been detected within the optical axis. The target has been detected.

Note: The LS-7000 Series in self-timing hold mode cannot be used for the following

measurement applications, when the LS-7000 Series will be always in measurement operation regardless of whether there is a target or not (because the internal measured value always exists). Example: • T-EDGE (Top edge) measurement

• B-EDGE (Bottom edge) measurement

• SEG (Segment) measurement of 001 and 002 edge widths

Analog Output Settings

The LS-7000 Series has analog voltage output according to the measured value. The range of analog voltage output is between –10 and +10 V.

Setting Range

The following analog output settings are available.

• Scaling (reference value): In reference value mode (LIMITS), the deviation is output as a positive or negative voltage based on the reference value of 0 V. Select the scaling of deviation from the following: 1, 2, 5, 10, 20, 50, 100, 200, 1000, 2000, 5000, and 10000 μm/V

• Scaling (threshold): In threshold mode, set the measurement values to be output at +10 V and –10 V respectively so that the scaling value will be decided. The absolute value of the difference between these values must satisfy the following condition. {(Measured value at +10 V) – (Measured value at –10 V)} X Value X varies with the minimum display unit. The relationship between value X and minimum display unit is shown below.

• Analog Update Mode The measured value after area calculation is output after the analog scaling of the value regardless of whether the display value is held or not. The function is ON/OFF selectable.

• Output Waiting Voltage Set the output voltage of the LS-7000 Series when the display shows “---.-----.” The items selectable are 0 V, 10.5 V, and HOLD (holding the previous voltage before the LS7000 Series began waiting for the result of the measurement).

■ Scaling

There is a difference in scaling settings between the LS-7000 Series in tolerance mode with reference values used and that with thresholds used. Refer to Tolerance Mode (LIMITS) on page 4-56 for details.

● Tolerance Mode with Reference Value

Based on a reference value of 0 V, the deviation is output as positive or negative voltage. The voltage can be changed while the result waiting status is “---.-----.” (See page 4-47)
