TR Electronic CEV58M SSI Encoder | 33-Bit Programmable

Description Product Overview TR Electronic CEV58M-SSI-1-D-1 is a high-precision rotary encoder. Specifically, this device combines single-turn and multi-turn measurement in one unit. Therefore, you get absolute position over many rotations without any need for homing. For example, it offers 33-bit total resolution with up to 32768 steps per turn. Moreover, the encoder handles up to 256000 revolutions. Furthermore, this encoder runs on 24 VDC (11 to 27 VDC range). Consequently, it draws only 80 mA when unloaded. As a result, the unit weighs between 0.3 and 0.5 kg.

Then, use flexible couplings to avoid shaft misalignment. Next, connect SSI clock and data lines with shielded cables. Also, keep cables away from high voltage sources. After that, tighten the mounting flange screws evenly. Finally, do not exceed the specified shaft loads. Commissioning & Maintenance First, download TRWinProg software from TR Electronic. Next, connect via SSI interface to set parameters. Then, program resolution, counting direction, and preset values. After programming, test the encoder at low speed first. For maintenance, check shaft alignment every 6 months. Also, clean the housing with a dry cloth only. Finally, no lubrication is needed for standard use. Compatibility This encoder works with any SSI master controller. For instance, it is compatible with Siemens, Rockwell, and Beckhoff PLCs. Additionally, optional incremental outputs provide dual feedback. Finally, use TRWinProg on Windows-based computers for programming.

What does “Single-/Multi-Turn” mean for this encoder? Single-turn measures position within one full rotation (360°). However, multi-turn counts total revolutions up to 256000 turns. Therefore, this combination gives you absolute position over many rotations. 2. Can I use this encoder at temperatures below 0°C? Yes, but you need the optional -20°C to 70°C version. Specifically, the standard version works from 0°C to 60°C only. Therefore, check your part number or ask us for the low-temperature option. 3. How do I set the resolution and other parameters? First, download TRWinProg software from TR Electronic. Next, connect the encoder to your computer via SSI. Then, the software shows all programmable settings. Finally, save your configuration to the encoder’s memory. 4. What happens if I exceed the maximum shaft load? Unfortunately, the bearing life will decrease significantly. As a result, you may see premature wear or binding. Therefore, always stay within 50 N axial and 100 N radial loads. Also, use flexible couplings to reduce stress. 5. Is this encoder short-circuit proof on all outputs? Yes, the 8 programmable push-pull outputs have short-circuit protection. However, the SSI data output and power input do not have this protection. Therefore, double-check your wiring before powering on. 6. Which shaft diameter option should I choose? First, match your existing coupling or motor shaft. Available sizes include: 6 mm, 8 mm, 10 mm, 12 mm, and 3/8 inch. Therefore, measure your shaft carefully. Then, choose the same size for a direct fit. 7. Can I get both SSI and incremental outputs on one encoder? Yes, the incremental interface is an optional feature. Consequently, you get square wave signals (K1±, K2±) along with SSI data. However, specify this option when ordering if you need both outputs. Selection Guide Choose CEV58M-SSI-1-D-1 when you need absolute SSI feedback with high resolution. Pick this model for single-turn and multi-turn measurement in one device. Select the standard temperature version (0 to 60°C) for indoor factory use. However, order the optional -20 to 70°C version for cold storage or outdoor applications. Additionally, add the incremental output option if you need speed feedback and position data. For shaft sizes, match your existing coupling exactly to avoid adapter costs. Finally, avoid this encoder if you need higher than 12000 rpm or Profibus/EtherCAT interfaces.
