3.2Basic Operations in the Standard Counter

3.2.1Turning 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. If the main power switch is on and this switch is off, only the display will be off, although the power is supplied to the counting circuits and the Linear Scales.

NOTE • For normal operation after the power has been turned on the main power switch on the rear panel should be left on, and the counter should be turned ON/OFF using the display ON/OFF switch on the front panel.

•If the display is blinking after the power is turned on using the display ON/OFF switch, this indicates that the displayed value is of no use. If this happens, cancel the value using the Cancel key, then reset the machining datum point.

•Always operate the keys only with fingers. If a key is pressed with a sharp tip such as a screwdriver, it may be damaged.

3-2	No. 99MBE032A

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 “3.2.5 Saving and recalling a datum point using the scale reference point”, set a machining datum point.

2)Turning the power off

By pressing the display ON/OFF switch, the display can be off.

3)Turning the power on again

Press the display ON/OFF switch on the front panel. The display will be on.

NOTE • If there happened an abnormality in the power line, such as a power failure, the next time the power is turned on using the display ON/OFF switch, the display will blink as described in 1) above. If this happens, set the reference point for machining again.

•When the display is blinked even if parameter No. 15, described in Chapter 4, has been set to “Save display”, this indicates that the displayed value is of no use. If this happens, set the reference point for machining again.

No. 99MBE032A

3-3

● 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.

By pressing the display ON/OFF switch, the display can be off.

3)Turning the power on again

Press the display ON/OFF switch on the front panel. The display will be on.

3.2.2Counting and displaying

This section is for the user who is using the KA counter with a minimum resolution of 0.0005 or 0.0001mm (0.5 or 0.1µm).

The user who is using it with a minimum resolution of 0.005 or 0.001mm (5 or 1µm) may skip this section.

•In order to expand the display range of the KA counter, the counting range in the + count direction and the - count direction are different.

The counting range when the KA counter is used with the minimum resolution of 0.0005 or 0.0001mm (0.5 or 0.1µm) is as follows:

+9999.9999 to -999.999 (approximately +10m to -1m)

3-4	No. 99MBE032A

3. BASIC OPERATIONS

3.2.3Switching 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

0A 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 “3.2.6 Setting the machine origin with the AT700 series”.

1 to 9

A coordinate system used for performing usual machining operation.

3.2.4Zero-set

Resets the display value for each axis to zero.

•Resets the X-axis value to zero.

*Zero-adjustment cannot be performed at coordinate 0.

3.2.5Preset

Set an arbitrary value onto the arbitrary axis through the key entry. Preset values can be saved in memory for each coordinate so that they can be retrieved even after the system power is reset.

•Preset -12.3 for the X-axis.

No. 99MBE032A

3-5

•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.

IMPORTANT • Preset data stored in the KA counter is the data input by the most recent preset operation.

•The preset data stored in the KA counter has been saved on the basis of coordinate systems described later.

•If data is preset through operation of the touch signal probe or zero-approach function (described later), the preset data stored in the KA counter will be changed to those values.

•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.

•Even if the counter exceeds the counting range, Error 30 will not be displayed during numeric entry. The error message will be displayed after numeric entry has been completed.

•Do not displace any axis scale too much while presetting is being performed.

•Zero-adjustment cannot be performed at Coordinate 0.

3-6	No. 99MBE032A

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. If this is the case, perform offset correction procedure described below for the axis where Error30 has occurred, then the normal state will be restored.

Exercise care when presetting a large value exceeding the maximum preset value.

•Operation at the occurrence of an overflow

1.Preset a value (larger than the maximum preset value).

2.An error occurs. (E.g. Error20)

3.Repeat steps 1 and 2.

•Maximum preset value

Resolution	Maximum preset value
0.01/0.05 mm	+500000.00 (500 m)
0.001/0.005 inch	+200000.00 inch
0.001/0.005 mm	+50000.000 (50 m)
0.0001/0.0005 inch	+2000.0000 inch
0.0001/0.0005 mm	+5000.0000 (5 m)
0.00001/0.00005 inch	+200.00000 inch

•Overflow correction procedure

a.Press the [▼], [SET], [X] (or [Y] or [Z]), [0], and [LOAD] keys in this order.

b.Move the linear scale to pass through the origin mark.

For the user who is using the KA counter with a minimum resolution of 0.0005 or 0.0001mm.

When data to be preset is smaller than or equal to 1m, the display method of the most significant digit and the sign differ from the normal preset. It alternately displays the sign and the most significant digit as shown in the figure below.

•Example) +9999.9999

Alternately displays a cursor and a numeric.
