To install the , 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 six M2 screws with a recommended torque of 0.3Nm.
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 1.5mm nominal. For ease of mechanical mounting compensation, the recommended distance is 1.6 - 0.05mm. Use rotor shims to compensate for any mechanical discrepancies.
3. Electrical Interconnection: The encoder has two operational modes: absolute position over SSi or BiSS-C, and setup mode over NCP (Netzer Communication Protocol). Connect the encoder according to the color code of the interface wires. For SSi/BiSS-C, connect the clock and data wires, as well as the ground and power supply. For NCP, use a 9-pin D-type connector to connect the encoder to the RS-422/USB converter.
4. 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. Use a 4.75 to 5.25 VDC power supply.
5. 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, USB 2 communication ports, and NET Framework V4 minimum. Run the software and verify proper communication with the encoder.
6. Mounting Verification: Use the Encoder Explorer tool to perform mechanical mounting verification. Start the data collection and rotate the shaft to collect fine and coarse channel data. The software will indicate whether the mechanical installation is correct or incorrect.
7. Calibration: After mounting verification, perform offset calibration to compensate for the DC offset of the sine and cosine signals. Start the data acquisition while rotating the shaft and collect data over the working sector. Then, perform CAA calibration to align the coarse/fine channels by collecting data from each point. Set the encoder zero point to the desired mechanical position.
8. 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. Check for even distribution of the reading data on a thin circle. Higher jitter may indicate system noise.
