1. Product Introduction & Model Decoding

Model definition breakdown

• USAGED: Totally enclosed self-cool servo base series with brake configuration;

• 30: 2.9kW power class;

• AS: Modified special stator winding + customized internal wiring layout (different from standard A-type);

• 2: Solid parallel key output shaft;

• S: Custom encoder pin definition & internal cable arrangement;

• E: European specification standard, EU connector layout, CE wiring standard for overseas export machine original matching.

2. Electrical Specifications

• Rated continuous output: 2.9kW, rated current: 26A;

• Rated speed: 1500rpm, continuous rated torque: 18.6Nm; peak overload torque reaches 3×rated torque for heavy startup & shock load resistance;

• Built-in DC24V electromagnetic brake: energize to release shaft, power cut locks output shaft mechanically to prevent vertical slide down;

• Feedback: UTMAH-B15ASB differential line incremental encoder, exclusive SE-version pinout only fit CACR-SR70E EU-spec servo amplifier without wire modification;

• Stator insulation Class F, built-in winding temperature sensor to feed overheat signal to drive for thermal protection; built-in surge absorption circuit for anti-interference against field power spike and EMI disturbance.

3. Mechanical & Environmental Parameters

• Operating ambient temp: 0℃ ~ +40℃; storage temp: -20℃ ~ +70℃;

• Working humidity: 5%~80%RH non-condensation; derate load when install elevation＞1000m due to degraded heat dissipation;

• Anti-vibration: withstand 10Hz~55Hz industrial regular vibration; forbid installation in corrosive gas, splashing liquid and heavy conductive dust environment.

4. Drive Matching & Control Mode

5. Multi-protection & Fault Alarm

1. Winding overheat → drive overload stop protection;

2. Encoder open circuit/poor contact → dedicated encoder fault alarm on drive panel;

3. Winding short/input overcurrent → hardware overcurrent immediate shutdown;

4. Brake coil open/short → auxiliary warning output on servo unit;

   All signal circuits adopt noise suppression component to improve anti-electromagnetic interference ability for complex workshop environment.

6. Replacement & Maintenance Instruction

• Direct replacement requires identical USAGED-30AS2SE; domestic K-version USAGED-30A22K or non-brake variant cannot direct swap unless rewire connectors and reset full servo parameters;

• Before disassemble brake/bearing/encoder maintenance: cut off main 3-phase power + DC24V brake supply, wait ≥15min for DC bus capacitor full discharge to avoid high-voltage shock hazard;

• Periodic maintenance: tighten rear triple connector terminals every 3 months; replenish high-temperature bearing grease after 8000 cumulative running hours; clean housing dust every half-year to maintain original heat dissipation efficiency; random wiring change of encoder/brake leads will cause runaway or driver permanent fault lock.
