esd noTes
Although the DF-150 Electric Encoder is insensitive to ESD and parasitic capacitive coupling from adjacent AC voltages, we highly recommend to enable a discharge path with <20 kΩ between the machine shaft and the electronics ground. Shielding: the Electric Encoder housing material is non­conductive polymer – ULTEM, the internal ground (return) path of the 5V power supply IS NOT CONNECTED to the cable shielding. We highly recommend grounding the cable shielding through the connector body or by other means.
Note: During high-speed rotation, bearings may isolate the shaft from its grounding. It is essential the shaft remain grounded using a sustainable method during such high-speed operations.

3. PRODUCT OVERVIEW
3.1
oVerView
The DF-150 absolute position Electric Encoder™ is a revolutionary position sensor originally developed for harsh environment critical applications. Currently it performs in a broad range of applications, including defense, homeland security, aerospace, and medical and industrial automation.
The Electric Encoder™ non-contact technology relies on an interaction between the measured displacement and a space/ time modulated electric field. The DF-150 Electric Encoder™ is semi-modular, i.e., its rotor and stator are separate, with the stator securely housing the rotor.

5. ELECTRICAL INTERCONNECTION
This chapter reviews the steps required to electrically connect the DF-150 with digital interface (SSi or BiSS-C).
connecting the encoder
The DF-150 operates has two operational modes: (i) i. Absolute Position over SSi or BiSS-C: This is the power-up default mode.
(ii) Configuration and setup mode:
This service mode provides access via USB to a PC running Netzer Encoder Explorer application (on MS Windows 7/8). Communication is via Netzer Communication Protocol (NCP) over RS-422 using the same set of wires. Use the following pin assignment to connect the encoder to a 9-pin D-type connector to the RS-422/USB converter CNV-0003.

5.3 Electrical connection and grounding
The DF-150 does NOT come with specified cable and connector, however, do observe grounding consideration:
[1] The cable shield does not connect to the power supply return line. [2] Ground the host shaft to avoid interference from the host system,
which could result in encoder internal noise.
Note : 4.75 to 5.25 VDC power supply required

■ Mechanical Mounting
■ Electrical Connection
■ Connecting Encoder for Calibration
■ Encoder Explore Software Installation
Run the Electric Encoder Explorer tool (EEE). Ensure proper communication with the encoder: (a) The status bar indicates successful communication. (b) Encoder data displays in the Encoder data area. (CAT No., serial No.) (c) The position dial display responds to shaft rotation.
7.2
meChaniCal insTallaTion VerifiCaTion
The Mechanical Installation Verification provides procedures to ensure proper mechanical mounting by collecting raw data of the coarse and fine channels during rotation. (d) Select [Mechanical Mounting Verification] on the main screen.

8.1
offseT CalibraTion
For optimal performance of the DF-150 Electric Encoder, the inevitable DC oset of the sine and cosine signals must be compensated over the operational sector. After successfully completing the Mounting Verification procedure: (a) Select [Calibration] on the main screen.
(b) Start the data acquisition while rotating the shaft.
The progress bar (c) indicates the collection progress. Rotate the axis consistently during data collection—covering the working sector of the application end to end—by default the procedure collects 500 points over 75 seconds. Rotation speed is not a parameter during data collection. Data collection indication shows for the fine/coarse channels, a clear “thin” circle appears in the center (d) (e) with some oset.

Caa CalibraTion
The following calibration aligns the coarse/fine channel by collecting data from each point of both channels. Select [Continue to CAA Calibration]
In the CAA angle calibration window, select the relevant option button from the measurement range options (a):
• Full mechanical rotation – shaft movement is over 10deg -
recommended.
• Limited section – define operation of the shaft in a limited
angle defined by degrees in case of <10deg
• Free sampling modes - define the number of calibration
points in the total number of points in the text box. The system displays the recommended number of points by default. Collect a minimum of nine points over the working sector.
• Click the [Start Calibration] button (b)
• The status (c) indicates the next required operation; the
shaft movement status; the current position, and the next target position to which the encoder should be rotated.
• Rotate the shaft/encoder to the next position and click the
[Continue] button (c) - the shaft should be in STAND STILL during the data collection. Follow the indication/interactions during the cyclic process for positioning the shaft --> stand still --> reading calculation.
• Repeat the above step for all defined points. Finish (d)
• Click the [Save and Continue] button (e).
The last step saves the osets CAA parameters, completing the calibration process.

JiTTer TesT
Perform a jitter test to evaluate the quality of the installation; the jitter test presents the reading statistics of absolute position readings (counts) over time. Common jitter should be up +/­three counts; higher jitter may indicate system noise.
