9.Function of External Inputs

Select the function of the external inputs.

Before starting a measurement

Ensure that the distance or angle actually traversed matches the displayed value and direction. Deviations may be due to the following causes:

•Signal period

•Counting direction

•Error compensation

•Scale factor

•Application (1 axis or 2 axes; formula for coupled position)

•Distance-to-go display

REF Reference Mark Evaluation

The ND 287's REF reference mark evaluation feature automatically re-establishes the relationship between axis-slide or measuring-probe positions and display values that you last defined by setting the datum.

If you do not use the REF feature, the datums will be lost once the ND is switched off.

Actual Value/Distance-To-Go

In the Actual Value operating mode, the ND always displays the current actual position of the encoder, relative to the active datum.

In the Distance-To-Go operating mode, you enter the desired nominal position and simply traverse to the display value zero.

The distance-to-go is displayed with a reversed algebraic sign. For example, the distance-to-go has a positive sign if the axis direction from the actual towards the nominal position is negative.

I: Actual position

S: Nominal position

R: Distance-to-go

Sorting and Tolerance Checking

=

=

<

>

To sort the parts, the ND 287 compares the displayed value with an upper or lower sorting limit, and displays the sorting result in color in the status display as a value or with one of the symbols < = >. In addition, a corresponding signal is available at switching output X41. Press the TOLERANCE CHECKING soft key to open the form for defining the sorting parameters and the sorting limits.

The sorting and tolerance checking function is always effective for the currently displayed value, also when measurement series, minimum/ maximum display, SPC or coupled positions are active.

Display Freeze

In order to read the display in spite of quickly changing values, the display can be frozen. The position value is counted internally until a new display value is called.You can freeze the display through a switching signal "Output measured value" to X41, the CTRL B command, or by pressing the PRINT soft key.

The MEASURED VALUE OUTPUT parameter in the Job Setup menu offers the following possibilities for settings:

•Concurrent Display

The display value always matches the measured value.

•Frozen Display

The display remains stopped, but is updated by every measured value output.

•Frozen/Con. Display

The display is only stopped during measured value output.

Measurement Series

The ND 287 can store measurement series with up to 10000 measured values. They can be evaluated internally or they can be read out in a block.

Setup Series of Measurements

•Measured-value recording through the ENTER key, an external signal or sampling intervals.

•Number of measured values.

•Definition of sampling intervals (20 ms to 60 s) and time slot.

Start Measurement Series

•By pressing START MEAS. SERIES.

•By sending an external signal to X41.

Switching-off the ND or starting a new measurement series deletes the values of the previously recorded measurement series.

Stop Measurement Series

•Automatic stop when the defined number of measured values is reached.

•By pressing STOP MEAS. SERIES.

Measurement Series Analysis

The measurement series can be displayed as

•Statistical data

•Diagram

•Measured value table

Export Measured Values

Press the EXPORT soft key to start transmission of the measured value table.

Minimum/Maximum Display

During the measurement series you can press the SELECT DISPLAY soft key to switch from the actual value display (ACTL) to the display of the minimum value (MIN), the maximum value (MAX) or the difference between minimum and maximum value (DIFF).

SPC Statistical Process Control

For Statistical Process Control, the ND 287 can store up to 1000 measured values in a non-volatile FIFO memory.

SPC Setup

•Number of samples and data per sample.

If you change these values, the data in the FIFO memory will be deleted.

•Upper and lower tolerance limits (same as sorting limits) and nominal value.

•Control limits for control charts.

•Distribution (symmetrical, left-hand or right-hand limit).

•Measured-value recording through the ENTER key or an external signal.

Record SPC Values

•Press the START SPC soft key to start data acquisition for SPC.

•Press the STOP SPC soft key to interrupt the SPC function. The ND 287 is then available for other measuring tasks.

•Press the START SPC soft key to restart measurement of the defined number of samples.

•The sample counter in the message line indicates the number of the current sample being measured, the number of the measurements performed and the total number of samples to be measured.

Before starting a new SPC measurement, select DELETE STATISTIC to delete old SPC values from the FIFO memory.

SPC Analysis

While the data is being measured, the ND can display the current status as

•Statistical data

•Graph (for the last 30 values)

•Histogram with 10 classes

•Control chart for average value x, standard deviation s and range r

(difference between maximum and minimum value) of a sample

Axis Coupling

Input X2 is available for an additional input assembly (option). Possible options:

•Encoder module for connecting a second encoder

•Analog module for connecting an

analog sensor with ± 10 V Descriptions are included with the modules.

X1 and X2 can be displayed separately or they can be coupled through mathematical functions. You can switch the display by soft key or through a switching input at any time.

The following axis displays are possible:

•Input X1

•Input X2

•Sum of X1 and X2

•Difference between X1 and X2

•Any function for coupling X1 and X2

Special features of coupled positions

•If PRESET is used, X1 is set to the value entered, and X2 is set to zero.

•If RESET is used, a value other than zero may be displayed depending on the programmed formula (e.g.: 5 if "X1 + X2 + 5").

•The values of the currently active axis display are used for SPC.

•If two axes are coupled, the finer of the two display resolutions will be used.

•If axis values are used as divisors, division by zero or display overflow may cause a temporary error message.

•If an analog sensor is connected to input X2 and the ENCODER TYPE field under Encoder Setup, Input X2 is set to COMPENSATION, the ND 287 behaves in the same way as a single-axis display unit.

•If COMPENSATION is selected, the formula for axis-error compensation is determined automatically. You only enter the coefficient of expansion and the reference temperature.
