| Component | Inspection Interval | Action | |-----------|---------------------|--------| | Cooling fan | Every 6 months | Listen for unusual noise; replace if bearing fails (part # ESDA-FAN-01) | | DC bus capacitors | Annually (under 40°C) | Measure capacitance; replace if below 85% nominal | | Battery (absolute encoder) | Every 2 years or when battery low alarm (A-91) appears | Replace with CR17450 lithium cell – manual warns not to use alkaline | | Shaft seal | Every 5000 operating hours | Check for oil/grease leakage in vertical mounting |
: Always confirm the one-to-one correspondence between U, V, W output terminals and motor binding posts to prevent overspeeding or equipment damage.
| Alarm Code | Error Description | Typical Causes & Solutions | | :--- | :--- | :--- | | | Low Voltage | - Input power phase loss or low voltage. - Main circuit capacitor deterioration. | | AL-02 | Overvoltage | - Power supply voltage is too high. - Regenerative braking resistor is open or disconnected. | | AL-03 | Overload | - Motor shaft is locked or load is excessive. - Motor output wiring (U, V, W) is incorrect. | | AL-04 | Overcurrent | - Drive output short-circuit or ground fault. - Power transistor (IGBT) module failure. | | AL-05 | Encoder ABZ Signal Error | - Faulty encoder wiring or connector. - Encoder internal failure. | | AL-10 | Motor Overcurrent | - Incorrect motor parameter settings. - Load inertia is too high for the selected gain settings. | | AL-11 | Position Error Excess | - Position command pulse frequency is too high. - Motor is unable to follow command due to stall or gain settings. | | AL-12 | Motor Overspeed | - Speed command input voltage is too high. - Speed loop gain (Pn101) is set too high. | | AL-15 | Drive Overheating | - Ambient temperature exceeds specification. - Cooling fan failure or blocked ventilation. | esda servo motor manual
ESDA servo motors are high-performance industrial automation components known for precision speed, torque, and position control. This comprehensive manual provides the technical specifications, wiring configurations, parameter settings, and troubleshooting steps required to safely commission and maintain your ESDA servo system. 1. Safety Guidelines and Precautions
If your motor features an integrated holding brake, it requires an external 24VDC power supply. Do not power the brake directly from the drive's internal 24V I/O supply. Use a surge-absorbing diode or varistor across the brake relay contacts to suppress voltage spikes when the brake engages or releases. 4.

Every ESDA servo motor features a nameplate detailing its electrical and mechanical boundaries. Ensure your drive output matches these requirements. Standard Range / Values 220V AC (Single/Three-Phase) or 380V AC (Three-Phase) Feedback Device | | AL-02 | Overvoltage | - Power supply voltage is too high
The ESDA servo system requires distinct separation between high-power lines and low-voltage control signals.
The ESDA servo motor manual provides detailed specifications for each motor model, including:
