SEW-EURODRIVE OG73SSN1024 Sine Encoder
An OG 73 S motor-feedback encoder with 1024 sine/cosine signal periods per revolution.
Key Information
OG73SSN1024 identifies an SEW-EURODRIVE OG 73 S sine encoder execution used for motor speed and position feedback. The SN1024 designation identifies the sine/cosine feedback type and 1024 signal periods per revolution.
Mechanical mounting, connector or terminal execution, supply, explosion-protection marking and the motor option must be confirmed from the complete encoder and motor labels.
Functions
- Generates incremental sine/cosine feedback for speed and position evaluation by the connected drive system.
- Provides 1024 signal periods per revolution for interpolation by compatible feedback electronics.
- Mounts as part of a documented SEW motor-feedback arrangement rather than as a universal stand-alone encoder.
- Supports controlled motor replacement and commissioning when encoder alignment and drive parameters are preserved.

Installation
- Record the motor, encoder and drive nameplates together before disassembly.
- Protect the encoder from impact, shaft load, contamination and electrostatic damage.
- Use the manufacturer alignment and coupling procedure for the exact motor execution.
- Verify signal tracks, direction, shielding, feedback recognition and zero or commutation reference before running the axis.
Lifecycle
- Keep the encoder code linked to the complete SEW motor option and drive parameter record.
- Do not substitute a different OG 73 output variant because signal interface and evaluation electronics can differ.
- For a replacement enquiry, include both the encoder and motor labels plus connector and mounting photographs.
FAQ
Can OG73SSN1024 be selected from the 1024 designation alone?
No. The motor option, mechanical mounting, electrical interface, connector and approval marking must also match.
Is OG73SSN1024 interchangeable with another OG 73 encoder?
Only an exact cross-reference covering signal type, mounting, shaft, connection and drive evaluation can establish interchangeability.
What motor data is needed with an OG73SSN1024 enquiry?
Provide the complete SEW motor order code, serial number, drive type, encoder label and photographs of the installed mounting and connection.
What installation error most threatens OG73SSN1024 operation?
Incorrect mechanical alignment or feedback wiring can cause signal faults, unstable control or wrong direction; follow the exact motor procedure.
Should the drive project be saved before changing OG73SSN1024?
Yes. Preserve feedback settings, motor data, direction, offsets and commissioning records before removal.
What should be checked after installing OG73SSN1024?
Confirm encoder recognition, signal quality, direction, speed feedback, zero or commutation reference and controlled low-speed axis behavior.
