- Setting Up The Unit
- Error Compensation
- Your digital readout (DRO) system helps you to improve productivity. It decreases the number
- of scrapped parts, as you no longer have to be concerned about making mistakes related to
- counting the revolutions on the dials. Your DRO system also helps to eliminate some errors
- related to ballscrew backlash.
- Your DRO system will operate to its published accuracy, provided all components are in
- working order and properly installed. Field calibration is not necessary.
- Accuracy problems with machined parts may be caused by machine error, DRO system error,
- or a combination of both. The first step in determining the source of error is to check the DRO
- system. You do this by comparing the movement of the Newall reader head to the position
- reading shown on the display. You need a high accuracy standard, such as a laser
- interferometer. You can use a dial indicator to check short distances, but a laser
- provides the best results. If you have to use a dial indicator, be sure it is the highest available
- accuracy.
- To check the accuracy of the DRO system:
- 11
- 1. Place the target of the laser or the needle of the dial indicator directly on the Newall reader
- head. It is absoluy critical that you take the readings directly from the Newall reader head. If
- you have to use a dial indicator, be sure that the needle of the indicator is perpendicular to
- the reader head and not angled. If you take readings anywhere else on the machine, machine
- errors may distort the results.
- 2. When the reader head moves, the movement registers on the laser / indicator and DRO
- display.
- 3. Set the laser / dial indicator and DRO position displays to 0.
- 4. Make a series of movements and compare the position readings between the laser / dial
- indicator and the DRO display. If the readings match within the accuracy specified, then you
- know that the DRO system is operating properly. If this is the case, you can proceed to the
- next step: evaluating the machine errors. If the readings do not match, you must repair the
- DRO system before proceeding with error compensation.
- To evaluate machine errors:
- 1. Put the laser target / dial indicator on the part of the machine where the machining is done.
- 2. Make a series of movements and compare the position readings between the laser / dial
- indicator and the DRO display. The difference between the laser / dial indicator reading and
- the reading on the DRO display is your machine error.
- 3. Plot the machine error along the entire axis of travel to determine the nature of the error. If
- it is a linear error, you can use linear error compensation. If the error is not linear, you should
- use segmented error compensation.

- Linear Error Compensation
- In this mode, you can apply a single constant correction factor for each axis to all displayed 12
- measurements. You calculate the correction factor, and specify it in parts per million (ppm).
- In this mode a single constant correction factor for each axis is applied to all displayed
- measurements.
- Error
- Travel
- As you follow the procedure you must ensure that you either use a stepped standard, and
- approach each edge from the same direction; or if you must approach each edge from
- opposite directions, then subtract the width of the tool or measuring probe from the value
- displayed on the DP700.

- Setting Up The Unit
- Linear Error Compensation Setup
- This setting allows you to setup compensation factors for linear errors. There are two
- methods of entering compensation values Teach mode and Program mode.
- Teach Mode
- Teach Mode
- Teach mode is an easier way of calculating linear errors by using the DP700 to automatically
- calculate the error, by comparing the actual measurement and the physical movement.
- The procedure to do this is shown below.
- Error comp select screen is displayed
- Press the axis select key next to the ‘X’, ‘Y’ or ‘Z’ axis which requires linear compensation
- Press the key to Navigate to Linear. Press
- Press the key to Navigate to Teach. Press

- Program Mode
- First you must determine the correction factor required.To do this you use the following
- equation. (In the following example the standard distance is 500.000mm and the measured
- distance is 500.200mm.)
- Correction factor = error / actual x 1,000,000
- Correction factor = (500 - 500.200) / 500.000 x 1,000,000
- Correction factor = -400
- Error comp select screen is displayed
- Press the axis select key next to the ‘X’, ‘Y’ or ‘Z’ axis which requires linear compensation
- Press the key to Navigate to Linear. Press

- Segmented Error Compensation
- The scale travel is broken down into as many as 200 user-defined segments, each with their
- own correction factor, measured against a high-accuracy standard. The following parameters
- need to be identified:
- Starting point - zero
- 5
- 1
- Error
- 4
- 2 6
- 0
- Travel
- 3
- Reference point Correction points
- Each Correction Point is measured with respect to the Starting Point - zero - which is usually
- set close to one end of the scale. The Reference Point can be set anywhere along the scale,
- and does not need to coincide with either the absolute datum or any of the correction points.
- However, it may be convenient to make the absolute datum and the reference point the
- same.
- Always approach the Starting Point, Correction Points and Reference Point from the same
- 14
- direction. If you do not, then the size of the tool or probe will render the measurement
- inaccurate.

- Digifind / Reference Function
- The DP700 comes equipped with Digifind, a feature unique to Newall digital readout
- products. Digifind eliminates the risk of losing your position and datum Set-Up.With Digifind,
- precise Set-Up of a workpiece is carried out only one time.
- When the DP700 is powered on, it displays the position at power off, compensated for any
- movement of a Spherosyn transducer up to 0.2500" (6mm) and a Microsyn encoder up to
- 0.1000" (2.5mm) in either direction since the unit was last used. If the machine has moved
- beyond 0.2500" (6mm) - Spherosyn [0.1000" (2.5mm) - Microsyn], Digifind allows a
- quick means to find the datum if lost.
- A mark must be made on both a stationary part and moving part of the machine.The marks
- must be aligned and will serve as the machine "home" position.
- The mark must be indelible, and it must allow the operator to move the machine to within a
- 0.2500" (6 mm) - Spherosyn [0.1000" (2.5mm) - Microsyn ] band around the
- mark at any time. Alternatively, you can use a convenient reference point on the workpiece

- Standard Functions
- Sub Datums / Memory
- The DP700 can store up to 200 SDM (Sub-Datum) positions, or machining steps into the
- memory. Using SDM allows the operator to work to zero by calling up stored dimensions,
- instead of "working up" to drawing dimensions. This eliminates the need to constantly refer to
- the drawing, and reduces the possibility of scrapping parts due to miss-red dimensions. It also
- speeds up positioning because the operator works to zero.
- The SDMs are stored as co-ordinates relative to the absolute datum position. If the absolute
- datum position changes, the SDMs will "shift" to the new datum.
- Once a repetitive sequence of co-ordinates is entered into SDM, the co-ordinates can be
- recalled at any time.The positions remain in memory until altered by the operator. Simply
- assign any SDM number 1 - 200 to each machining step. When machining, call up each step
- (SDM) number and work to zero.
- There are two ways to store Sub datums, Teach mode and program mode. See example

- Trouble Shooting Guide
- Symptom Solution
- • The DP700 maybe in sleep mode. press any key to exit sleep mode
- • Check that the power supply is correctly connected to a working mains outlet
- The display is blank • Check that the power supply cables are not damaged
- • Check that the power supply voltage is 15 - 24Vdc ±10%
- • Check the power supply indicator is illuminated on the front of the DP700.
- Either the supply voltage is too low, or the power supply or mains supply has an intermittent
- The display works, but
- fault.
- resets from time to time
- without any keys being
- • Check that the power supply voltage is 15 - 24Vdc ±10%.
- pressed.
- • Check that all the connections are secure.
- The display works, but
- There may be a poor earth (ground) connection. Both the DP700, and the machine on which
- gives erratic readings,
- it is installed, must have proper earth (ground) connections.
- the last digit jitters or the
- measurements jump to
- There may be a problem with the encoder.
- new figures unexpectedly.
- The unit does not respond
- Disconnect the DP700 from its power supply, wait 15 seconds and then reconnect.
- to any key presses.
- This indicates that the unit is not receiving a proper signal from the encoder.
- ‘no Sig’ or ‘SIG FAIL’ • Check that the encoder connections are secure.
- appears in the display. • Check that there is no damage to the connectors or to the encoder.
- • Switch the DP700 off and back on again.
- • Swap the encoder to another axis to confirm whether the encoder or the DP700 is at fault.
- • Check the Encoder Type to ensure it is correct.
- • Check the Radius / Diameter setting. The Diameter setting causes the axis to read double.
- • Check the Error Compensation factors.
- • If using the Segmented Error Compensation, verify the datum position.
- • Swap the encoder to another axis to confirm whether the encoder or the DP700 is at fault.
- • Check that there is no damage to the encoder or its cable.
- Readings are incorrect.
- • Check that the encoder is fixed firmly and aligned correctly, as described in the Spherosyn / t
- t Microsyn Installation manual.
- • Check that there is no binding on the scale. With the scale brackets slightly loosened, you
- t should be able to slide the scale back and forth with minimal resistance.
- • If you have a Spherosyn scale, check that the scale is not bent, by removing it and rolling it
- on a flat surface.
- If the solutions suggested above do not solve your problem, contact Newall for further instruction.
- To swap encoders to trace a fault: 32
- 1. Check that the two axes are set to the correct encoder types.
- 2. Disconnect the DP700 power supply.
- 3. Disconnect the encoder from the malfunctioning axis and move to a working axis.
- 4. Reconnect the DP700 power supply and turn on.
- If the fault stays with the same encoder, then the encoder is at fault. If the fault does not follow with the
- encoder the DP700 is at fault.
- Providing you have not moved the machine more than 6.3mm (0.25”) for a Spherosyn Encoder or 2.5mm (0.1”)
- for a Microsyn Encoder, switching the power off and back on again does not lose the datum position.
