The installation process for the Netzer DS-58 Absolute Rotary Encoder involves several steps. Here is a step-by-step guide:
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. The encoder stator is centered by a circumferential step and attached to the host stator using three 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. You can use rotor shims for mechanical mounting compensation, with the recommended distance being 1.6-0.05 mm.
3. Electrical Interconnection: The encoder can be connected in two operational modes: absolute position over SSi or BiSS-C, or setup mode over NCP (Netzer Communication Protocol). For SSi/BiSS-C interface, follow the color code for the interface wires. For NCP setup mode, use the pin assignment to connect the encoder to a 9-pin D-type connector to the RS-422/USB converter.
4. Software Installation: Install the Electric Encoder Explorer (EEE) software on your computer. The minimum requirements are MS Windows 7/10 (32/64 bit), 4MB minimum memory, and USB 2 communication ports. Run the software and start using it.
5. Mounting Verification: Before calibration, perform mounting verification and rotation direction selection to ensure optimal performance. Use the Mechanical Installation Verification feature in the software to collect raw data of the fine and coarse channels during rotation. The software will indicate whether the mechanical installation is correct or incorrect.
6. Calibration: After successful mounting verification, you can proceed with calibration. The software provides options for offset calibration and CAA (Coarse and Angle Alignment) calibration. Follow the instructions in the manual to collect data and calibrate the encoder.
7. Setting the Encoder Zero Point: You can define the zero position anywhere in the working sector. Rotate the shaft to the desired zero mechanical position and use the "Set UZP" option in the Calibration menu to set it as the zero point.
8. Jitter Test: Perform a jitter test to evaluate the quality of the installation. The test will show the reading statistics of absolute position readings over time. Higher jitter may indicate system noise or installation issues.
Please refer to the Netzer DS-58 Absolute Rotary Encoder User Manual for more detailed instructions and illustrations of the installation process.
