To install the Netzer DS-90 Everight Position Encoder, follow these steps:
1. Encoder Mounting: Attach the encoder rotor to the host shaft by pressing it against a dedicated shoulder. Use a xxxx and washer or circular spring and washer to maintain pressure. Center the encoder stator and attach it to the host stator using three M2 encoder clamps.
2. Encoder Stator/Rotor Relative Position: The rotor is floating, so the proper relative axial mounting distance between the shaft shoulder and stator mounting recess should be 1.5 mm nominal. For ease of mechanical mounting compensation, the recommended distance is 1.6 - 0.05 mm. Use rotor shims to achieve the optimal recommended amplitude values.
3. Unpacking: The standard DS-90 package includes the encoder with a 250mm shielded cable. Optional accessories are available for purchase separately.
4. Electrical Interconnection: The encoder can be connected in two operational modes: Absolute position over SSi or BiSS-C, or Setup mode over NCP. Follow the provided color code for connecting the wires of the encoder to the appropriate interface.
5. Electrical Connection and Grounding: Ensure that the cable shield does not connect to the power supply return line. Ground the host shaft to avoid interference from the host system.
6. Software Installation: Install the Electric Encoder Explorer (EEE) software on a computer running MS Windows 7/10. The software allows for mechanical mounting verification, offset calibration, and general and signal analysis setup.
7. Mounting Verification: Use the EEE software to verify the mechanical installation by collecting raw data of the fine and coarse channels during rotation. Ensure proper communication with the encoder and check for correct mechanical installation.
8. Calibration: Perform offset calibration to compensate for the DC offset of the sine and cosine signals. Collect data while rotating the shaft and follow the instructions in the EEE software to complete the calibration process.
9. Setting the Encoder Zero Point: Rotate the shaft to the desired zero mechanical position and use the EEE software to set the zero point.
10. Jitter Test: Perform a jitter test to evaluate the quality of the installation. The test presents the reading statistics of absolute position readings over time. Higher jitter may indicate system noise.
11. Operational Mode: The DS-90 supports SSi and BiSS operational modes. The operational mode can be selected using the NanoMIC interface.
12. Mechanical Drawings: Refer to the provided mechanical drawings for specific installation configurations, such as end installation or smooth installation.
