Shaft Options
The TR Electronic CEV58M-SSI-1-D-1 supports multiple shaft diameters. Choose the version that matches your mechanical coupling.
Installation Guide
Follow these steps to install the CEV58M-SSI-1-D-1 correctly.
Mechanical Mounting: Secure the encoder flange to a rigid surface. Use flexible couplings to avoid shaft load.
Shaft Alignment: Keep axial load below 50 N and radial load below 100 N. Measure the load 10 mm from the mounting flange.
Electrical Connection: Apply 24 VDC power (11 to 27 VDC range). Use a Class 2 power supply for UL/CSA compliance.
SSI Wiring: Connect SSI-Clock+/- to your controller’s clock output. Connect SSI-Data+/- to the controller’s data input.
Parameter Setup: Connect TRWinProg software to program resolution and output code. Save settings to the internal memory.
Functional Test: Rotate the shaft slowly. Verify position data changes correctly on your SSI master.
Do not exceed 12000 rpm mechanical speed. The CEV58M-SSI-1-D-1 encoder requires proper grounding to avoid electrical noise.

Common FAQs
1. What is the maximum total resolution of the CEV58M-SSI-1-D-1?
This TR Electronic encoder supports up to 33 bits total resolution. That equals 32768 steps per turn over 256000 revolutions.
2. Can I use this CEV58M encoder in freezing temperatures?
The standard model works from 0°C to +60°C. Order the optional -20°C to +70°C version for cold environments.
3. How do I change the counting direction on the CEV58M-SSI-1-D-1?
You can program the direction using TRWinProg software. Alternatively, use the external F/R input pin for dynamic direction control.
4. What happens if the SSI clock frequency is too high?
The CEV58M-SSI-1-D-1 accepts 80 to 1000 kHz. Frequencies above 1000 kHz may cause data transmission errors.
5. Does this 9200 model require an external battery for multi-turn data?
No, the CEV58M-SSI-1-D-1 uses mechanical gears for multi-turn counting. It retains position even after power loss.
