SGDC-30AJA-FY16(B) is a customized 3kW class AC servo SERVOPACK manufactured by YASKAWA, belonging to Sigma-I SGDC standard servo platform, derived from standard SGDC-30AJA base model with FY16 customized option specification and B-version revised hardware configuration. The suffix FY16 stands for factory-specific customized I/O definition, special encoder interface or exclusive internal function setting, while marking (B) represents secondary hardware revision for structural and circuit optimization compared with original FY16 variant. This drive is designed to pair with matched YASKAWA 3kW permanent magnet AC servo motor for high-precision motion control in special automation equipment.

The unit adopts three-phase AC 200V input power supply, compatible with 50Hz/60Hz industrial power grid, rated matching power 3.0kW, continuous output current designed for supporting rated operation of corresponding 3kW servo motor. Internal DC bus operates within standard 280V~330VDC working range, output three-phase adjustable AC 0~230V to drive servo motor. It applies natural air cooling via built-in radiator without dependent cooling fan under rated load running condition. Ambient working temperature ranges from 0℃ to +55℃, storage temperature between -20℃ and +70℃, permissible ambient relative humidity below 90% without condensation.

This servo drive supports three mainstream control modes including position control, speed control and torque control, switching via internal parameter configuration according to on-site mechanical demands. Built-in automatic motor tuning function can identify motor coil resistance, inductance and encoder parameters automatically after wiring completion to optimize servo gain, improving positioning precision and operating stability.Standard part retains universal pulse command input, analog speed/torque signal input and multi-channel digital I/O terminals; FY16 customized section modifies partial terminal signal assignment and reserved exclusive functional parameters which are not listed in standard SGDC-30AJA parameter manual, needing factory supplementary document for parameter setting. Version B optimizes partial internal power circuit and anti-interference circuit design to strengthen stability under harsh electromagnetic working environment.Real-time operation monitoring is available to check bus voltage, output current, operating temperature and fault alarm code via front panel or upper computer debugging tool.

Install the drive vertically on rigid metal mounting base, reserve enough ventilation space around the unit: above and below over 50mm clearance, left and right side more than 30mm gap for heat dissipation. Separate power cable and control signal cable during wiring construction to avoid electromagnetic interference; power terminals connect main AC input and motor output with thick power wire, encoder and control I/O signal adopt shielded twisted cable. Reliably connect drive protective earth terminal to equipment grounding loop to reduce surge damage risk. Cut off all power supply and wait minimum 15 minutes for internal capacitor full discharge before opening housing for maintenance or wiring modification to prevent electric shock from residual high voltage.

When fault alarm triggers and code displays on panel, cut off main power first then inspect failure cause: overcurrent fault mostly comes from motor wiring short-circuit or motor winding damage; overvoltage results from power grid surge or rapid mechanical braking without matching external braking resistor; overheating is caused by blocked radiator dust or long-time overload operation. After removing abnormal trigger factor, reset fault by power restart or panel reset function before restarting equipment. If identical fault repeats continuously after regular troubleshooting, stop running and send for professional repair to avoid secondary damage of drive and matched servo motor.Carry out regular maintenance every 3~6 months based on site dust level, clean dust on radiator surface and retighten loose terminal screws to prevent poor contact heating failure. For long-term idle storage, place unit in dry sealed environment; if storage period exceeds one year, perform 30 minutes no-load power-on test before formal assembly and commissioning.

Mainly used for customized automation production equipment, special-purpose CNC machining equipment, precision packaging machinery, semiconductor processing equipment and multi-axis synchronous automation fixture transmission system, especially for equipment requiring customized I/O logic defined by FY16 option specification.
