1. Features and Applications
Position encoders in drive systems have to meet high and controversial demands. The demands opposing each other are high accuracy and resolution on the one hand and low mass, small dimensions and high measuring speed on the other hand.
• The concentration of multiple axes in rotation in very tight spaces, such as in semiconductorproducing machines, requires the miniaturization of the drives, bearings and encoders.
• High machining speeds and therefore high accelerations make low masses of the components in motion essential.
The optical RIK 4 incremental encoders from NUMERIK JENA are equipped with features which are supposed to fulfill these high requirements in an ideal way.
• Due to an interpolation circuitry which is integrated in a 15-pin D-sub connector, a resolutions down to 0.135 arc seconds is possible without any additional electronics.
• The permissible speed of rotation for a sinusoidal signal output amounts up to 22,000 rpm.
• The short-range position errors (interpolation errors) were significantly reduced by introducing an electronic compensation of amplitude and offset deviations of the coarse signals. This compensation functions without following error in all velocity ranges.
Additional features:
• Compact size and large mounting tolerances
• Low mass moment of inertia of the grating disk
• High measuring speed
• Online compensation (dynamic offset and amplitude control)
• Optional signal interpolation up to 100-times in the connector
• Possibility of electronic signal adjustment (signal optimization after mounting)
Applications:
• Automation technology
• Rotary axes
• Drive systems, especially direct drives and torque motors
• Instruments and machines used in semiconductor industry
• Robot and handling technology
• High-precision engineering
• Metrology
• Medical technology

2.3 Notes on Transport, Storage and Handling
Encoder
• Use the original packaging for transportation only!
• If possible, use only the original packaging for storage.
Grating Disk
• Use the original packaging for storage only!
!
• Please check the packaging and the seal for damages first! Once opened, scratches or contaminations on the grating disk cannot be complained anymore.
• Handle the grating disk carefully! Its surface is sensitive to scratching.
• Small surface errors evident at the time of shipping are due to the production process. These errors are no indication for a qualitiy defect and do not affect the encoder’s functionality.
• Handle the aluminum disk carefully please and protect it especially against mechanical deformation.
Unevenness of the disk influences the correct operation of the encoder.

6. Technical Data
6.1 Resolution and Accuracy (Definition)
Basically one has to differentiate between the resolution and the accuracy of a measuring system. The two parameters are not directly interdependent and may differ from each other.
Resolution
Resolution “A“ is defined as the smallest angular value that is still detected by the evaluating electronics
(display, control) when the grating disk is turned relative to the scanning head. The resolution can be calculated using the following formula:
A = Z · i · N [Increments/Revolution]
[Degrees]
Z i
Number of lines (grating disk)
Interpolation factor of the evaluation electronics
(5-times, 10-times, 25-times, 50-times or 100-times)
N Factor for evaluation mode (counter)
N for evaluation
Accuracy
Accuracy (extremes of direction deviations) is affected by
• graduation errors of the grating disk
• eccentricity of the graduation relative to the axis bearing
• radial eccentricity of the axis bearing
• deviations in the positions of the grating disk and the scanning head (mounting tolerances)
• interpolation error in signal processing
The accuracy is largely determined by the eccentricity of the graduation relative to the axis bearing and the radial eccentricity of the axis bearing. The error resulting from these factors is calculated using the following formula:
Δϕ = ± 412 e
Δϕ e

6.3 Calculation of the Attainable Speed of Rotation
The maximum attainable speed of rotation of the encoder is determined by the maximum output frequency of the interpolator and/or the maximum counting frequency of the operator‘s evaluation electronics.
In order to avoid counting errors, the interpolator‘s output frequency is matched to the counting frequency of the operator‘s evaluation electronics.
This adaptation is possible in discrete frequency steps.
The maximum attainable speed of rotation (n max
) is calculated according to the following formula: n max the [Hz]

6.5 Switch-On Behaviour
During power-up procedure of the encoder system the level of power voltage and signal lines must be below 250 mV.
!
If the encoder system will be powered-up at a residual voltage between a range of 250 and 400 mV, internal sensor parameter will not set correctly. This will lead to incorrect encoder signals.
This behaviour has to be observed especially during reset routines of controllers.

6.7 Cable
Scanning Head Cable (connection cable from scanning head to D-Sub connector)
• Provide a strain relief for the cable near the scanning head.
• The encoder cables and connecting cables must be laid away from sources of interference (e.g. mains cables, fuses, motors, magnetic valves or power supplies). Normally a distance of ≥100 mm will be sufficient.
• Install the cable in a way that it cannot be damaged by the rotating hub. Please pay attention to the

6.10 Electromagnetic Compatibility (EMC)
Please observe the following to ensure maximum protection against electrical and magnetic fields:
!
• The encoder must be mounted to a galvanic conductive surface. The mounting surfaces, the threads of the mounting screws and the threads in the machine must be free from electrically nonconductive coatings.
• Maintain the NUMERIK JENA shielding concept for the measuring system!
• Shielding for encoders without connectors:
- When connected directly with the evaluation electronics, ensure that the external shield of the
cable is well grounded
- If cable connectors (e.g. terminal strips, etc.) are used, connect the external shields of the
cables with each other and with the shielding of the cable connector
• When using additional electronics, connect the housing electrically conducting to ensure good galvanic conductivity. For insulated installation the housing should be connected at the shortest distance by an additional potential equalization line (Cu line with cross section ≥6 mm
2 machine’s protective ground.
) with the
• Please contact the NUMERIK JENA support or that of the appropriate manufacturer if you experience any problems when working with specific display or control units.

6.14 Online Compensation (Offset and Amplitude Control)
Contamination and mounting errors lead to interferences in the optical scanning of the grating disk by the scanning head and so to periodic deformations of the sinusoidal counting track signals, which are exemplified as
• Offset deviations
• Amplitude deviations
• Amplitude differences between the sine and cosine channels and lead to interpolation errors.

7.5 Mounting of the Grating Disk
To prevent deformation of the grating disk by external forces it is recommended to glue the disk to a hub (see image 19). Additionally the mounting and mechanical adjustment to a shaft will be simplified.
The use of a rotary table for mounting will be recommended. For optical vernier adjustment of the grating disk an adjustment microscope with line marking in the intermediate image plane should be used.
Recommended Mounting Steps:
2
3
1
4
Clean all adhesive surfaces by using a soft and lint-free rag. Use a solvent if necessary (e.g.
Acetone or Alcohol).
Center and fix the hub to the rotary table.
Apply an evenly spreaded adhesive layer to the bottom of the grating disk. The use of a twocomponent adhesive, e.g. “Epicol 230004” or an adhesive with similar properties is recommended.
Use an appropriate tool, e.g. a dispenser.
Place the grating disk on the hub carefully and center it primarily according to the outer diamter of the disk.
5
6
Focus the edge of the grating disk by using the adjustment microscope. Rotate the grating disk and determine the location of the minimum deviation a and the maximum deviation b of the concentricity (see image 20).
Focus the location of the minimum deviation a again and move the grating disk carefully by half the amount of the difference between deviation
a and deviation b. By doing so the centre of the incremental track and the pivot of the shaft will be aligned.
7
8
Weight down the grating disk by using an appropriate loading (see image 21) and let the adhesive cure for approximately 1 hour. Please prevent any damage or scratching of the grating disk by using an appropriate padding between disk and loading.
Focus the outer diameter of the incremental track of the grating disk for vernier adjustment. Rotate the disk and determine the location of the minimum deviation a and the maximum deviation b again.
9
Repeat as well as described in step 6. Examine the concentricity and repeat step 6 as often as necessary to reach the required concentricity deviation. Let the adhesive cure (e.g. “Epicol
230004”, curing time = 24 hours at room temperature).
10
Finally fix and center the hub to the shaft.
ATTENTION: Acetone and Alcohol are inflammable liquids!

Mounting Instructions
• Remove any residue of adhesive which appeared during the mounting procedure from hub and grating disk immediately.
• Please prevent any damage or scratching of the grating disk while removing the loading. The surface of the grating disk is very scratch-sensitive.
• Clean the surfaces by using a soft and lint-free rag. Use a solvent if necessary (e.g. Acetone or
Alcohol).
• Please pay attention to the data sheets and notes of the adhesive manufacturer!
ATTENTION: Acetone and Alcohol are inflammable liquids!

7.6 Mounting of the Scanning Head
• Clean all mounting surfaces of the scanning head and machine element before mounting. Remove the protection foil from the scanning window of the scanning head.
• Clean the scanning head surfaces carefully by using a soft and lint-free rag. Use a solvent if necessary (e.g. Acetone or Alcohol).
• The mechanical mounting of the scanning head can be done in two ways:

• Please pay attention to the indicated mechanical mounting tolerances (see point 7.3 and 7.4).
• Position the encoder cable including a strain relief near the scanning head (see also point 6.7).
• Connect the encoder cable to the evaluation electronics and pay attention to the pin assignment.
The evaluation electronics must be switched off!
• After connecting the encoder cable switch the evaluation electronics on and test the functionality.
• If there are errors in the function or during measurement, please read chapter 10 “Troubleshooting” first. If these information are not helpful for your problem, please contact the technical support of
NUMERIK JENA or an authorized subsidiary in your country.

8. Signal Adjustment with ADJUSTMENT TOOL
Before delivery the encoders from NUMERIK JENA will be tested and electronically adjusted under ideal mounting conditions. Furthermore, the sensor modules offer the possibility of an electronic signal adjustment after the mounting into the application. This allows the user optimize the encoder signals regarding to the mechanical mounting conditions (tolerances).
The ADJUSTMENT TOOL and the related EPIFLEX software was designed to simplify and make the signal adjustment more effective.
8.1 Functions of the ADJUSTMENT TOOL
• Representation of the sinusoidal counting signals with amplitude, offset and phase position
• Representation of the position and width of the index signal
• Evaluation of the mechanical mounting conditions
• Automatic signal adjustment and programming of the sensor module
• Electronic readjustment of the amplitude and offset of the sensor signals
• Adjustment of the position and width of the index signal
8.2 Dynamic Offset and Amplitude Control (Online Compensation)
The encoders of NUMERIK JENA are equipped with a dynamic amplitude and offset control (online compensation). The analog diode signals will be corrected to their nominal values in real time. This reduces measuring errors caused by contamination as well as from inaccuracies. The phase position between the sine and cosine signals and the position of the index signal are not influenced by the online compensation.
With help of the EPIFLEX Software the preadjusted nominal values of the online compensation can be influenced.
8.3 Scope of Delivery
• ADJUSTMENT TOOL black box
• Diagnostic cable to connect the measuring system
• USB cable to connect a PC
• USB - D-SUB - adapter cable (15-pin)
• Exchangeable 8-pin plug connectors
Image 25
SIMPLY PRECISE
33
8.4 EPIFLEX Software
The EPIFLEX software was especially designed for the ADJUSTMENT TOOL. It offers the user versatile possibilities to bring the encoder into service. It also allows the user to display the sensor signals and evaluate them without using an oscilloscope or other expensive hardware. Furthermore it is possible to program respectively optimize the encoder to the existing mounting conditions automatically.
The EPIFLEX software is available for free via download on the NUMERIK JENA website under www.numerikjena.de. Furthermore, one can order the software with an optional USB flash drive.
The EPIFLEX software is suitable for the following operating systems:
• Windows 7 / 8 (32 or 64 bit)

Further information about the ADJUSTMENT TOOL and the EPIFLEX software can be found on the
NUMERIK JENA website.

9. Cleaning
• Depending on the measuring system‘s mounting attitude and the ambient conditions, it may be necessary to clean the grating disk and sensor surface of the scanning head (scanning window for counting and reference track) occasionally.
• If the monitoring signal output by the scanning head is used, the encoder indicates that cleaning is necessary.
• When cleaning the components, ensure that the scanning window and grating disk are not scratched by any deposited particles!
• Dirt should be removed using a soft brush or oil-free compressed air.
• Use cotton balls or a soft and lint-free rag for cleaning. Use a solvent if necessary (e.g. Acetone or
Alcohol).
• Ensure that no solvent seeps under the grating disk! This could adversely affect the adhesive layer and thereby loosening the grating disk.
• ATTENTION: Acetone and Alcohol are inflammable liquids!

11.2 Speed Chart for Optical Rotary Encoder with Online Compensation
The maximum attainable speed of rotation of the encoder is determined by the maximum output frequency of the interpolator and/or the maximum counting frequency of the operator‘s evaluation electronics (e.g. controller or display).
Please take the suitable values for your application from the following charts and enter it into the corresponding place (for “X”) in the ordering key.
Pay attention to your chosen interpolation factor and the number of lines of the grating disk first. If you have found the respective information, please check if your evaluation electronics is able to achieve the needed counting frequency and the maximum speed of rotation. The maximum speed of rotation should not be exceeded.
The maximum scanning frequency of the encoder amounts to 200 kHz standardly, hence the maximum attainable speed of rotation will be derived from that. It is possible to increase the scanning frequency on request. This consequently enables a higher speed of rotation.
