Description

1. Product Introduction & Model Decoding

SGDB-2BADYS80A is a 2.0kW customized OEM AC servo amplifier belonging to Yaskawa original Sigma-I (S-series SGDB platform, pre Sigma-II) servo drive lineup, discontinued original mass production; available units are tested spare/refurbished parts for legacy equipment maintenance.

  • SGDB: Yaskawa original first-generation Sigma SERVOPACK drive series

  • 2B: Rated output power = 2.0kW, 200V input grade

  • AD: Dual command interface: ±10VDC analog speed/torque + external pulse position control

  • Y: Special internal regenerative circuit + customized I/O terminal pin definition

  • S80A: Exclusive factory OEM custom firmware version for designated machine setups, unique preset parameter table different from standard SGDB-2BADA general model.

    Matching motor: corresponding 2kW SGMG/SGMS series 200V-class Yaskawa rotary servo motor.

2. Main Electrical Specifications

  • Input power: Single-phase / Three-phase AC200~230V, 50/60Hz main circuit power supply; control power sourced internally from main circuit without separate auxiliary power input.

  • Rated continuous output power: 2.0kW; transient peak overload capacity up to 300% rated current for instantaneous heavy startup load. Max three-phase output voltage: AC0~230V PWM sine-wave output.

  • Built-in dedicated regenerative circuit (Y spec): no need for external regenerative resistor under conventional deceleration workload; S80A customization modifies regenerative threshold parameter by factory default.

3. Multi-Mode Control Configuration

Three switchable working modes via internal parameter setting:

  1. Pulse Position Control: Accept open-collector or line-driver differential pulse command via CN1 connector; supports CW/CCW dual pulse or A/B quadrature pulse input, configurable electronic gear ratio function.

  2. Analog Speed / Torque Control: ±10VDC analog reference signal for speed or torque command, adjustable input gain and offset via drive parameters.

  3. Optional fieldbus compatible (parameter enabled): reserve MECHATROLINK-I hardware base for bus command control (limited by S80A customized firmware setting).

CN1 terminal integrates standard digital I/O signals: Servo ON enable, fault reset, external JOG, positioning completion output, fault relay dry-contact output. CN2 is dedicated encoder feedback port supporting incremental encoder and battery-backed absolute serial encoder connection. Onboard RS232 port for Yaskawa proprietary adjustment software for parameter upload/download and runtime monitoring.

4. Complete Built-in Protection Functions

Full protection set including overvoltage, overcurrent, continuous thermal overload, power module overheat, encoder cable breakage, regenerative overvoltage, abnormal input power voltage, control circuit failure, communication error protection. Fault codes display on front LED digital tube, with external dry-contact alarm output for upper machine interlock stop control.

5. Environmental & Mechanical Specifications

  • Protection grade: IP20; mandatory installation inside closed electrical cabinet, prohibited direct splash, oil mist or conductive dust exposure.

  • Working ambient temperature: 0°C ~ +55°C (no condensation); storage temperature: -20°C ~ +85°C. Operating humidity: 10%~90%RH non-condensing.

  • Cooling method: forced air cooling with internal built-in cooling fan; mounting via cabinet screw fixing or DIN rail adapter. Product complies with CE industrial safety certification.

6. Function & Replacement Instruction

Equipped with automatic inertia identification and auto-gain tuning function to simplify field commissioning; front panel JOG inching operation for no-controller manual forward/reverse motor test. Internal dynamic brake circuit ensures rapid motor stop during emergency stop or unexpected power cut to avoid mechanical overrun; on-board nonvolatile memory stores historical fault records for troubleshooting.
Replacement note: Due to S80A OEM customized firmware and preset parameters, standard SGDB-2BADA cannot directly substitute this model; full parameter rewriting and I/O signal verification is required before replacement. Mainly applied on special customized automation equipment, precision feeding axes and original OEM processing machinery using this dedicated servo system.
