Description

1. Model Definition & Product Overview

SGDC-10AJA is standard non-customized 1.0kW compact DC-bus servo amplifier belonging to discontinued Yaskawa Sigma-I SGDC series, designed for multi-axis shared DC-bus industrial automation systems, universal general-purpose model without OEM locked firmware modification.
  • SGDC: Compact shared DC-bus type Sigma-I servo drive series (different from AC mains powered SGDB series)

  • 10: Rated 1.0kW output power grade

  • A: Dual command hardware supporting pulse position + ±10VDC analog speed/torque input

  • J: Standard internal power circuit for common DC-bus power supply architecture

  • A: Standard universal factory firmware, full parameter adjustable, no fixed OEM customized setting

Matching Servo Motor: SGMG-10A series 1.0kW, 200V-class Sigma-I servo motor, compatible with 8192P/R incremental encoder or battery-backed absolute encoder.

2. Electrical Ratings

  • Main Power Input: Common DC bus DC280~330VDC; independent separated terminal for control auxiliary power supply

  • Rated Continuous Output: 1.0kW, rated output current 7.6A, three-phase AC 0~230V PWM output; 300% short-time overload capacity for instantaneous startup/impact load

  • Built-in standard dynamic braking circuit; external brake resistor optional only under frequent high-cycle deceleration condition; no fixed braking threshold limitation as customized Y-suffix models.

3. Control Mode & Interface Specification

Three freely configurable control modes via full adjustable internal parameters:
  1. Pulse Position Control: Accept open-collector or differential line-driver pulse input (CW/CCW dual pulse / A/B quadrature pulse); electronic gear ratio fully editable without factory lock

  2. Analog Speed/Torque Control: External ±10VDC analog reference input; speed loop gain, zero offset all adjustable via parameter setup

  3. MECHATROLINK-I PCB pads reserved on PCB; bus communication function can be enabled by parameter modification upon customer requirement

  • CN1 Connector: Standard universal I/O pin definition including Servo ON enable, fault reset, positioning complete output, dry-contact fault relay alarm; standard industry pin assignment compatible with generic automation wiring, unlike Y-custom variant (such as SGDC-05AJAY16) with revised CN1 mapping

  • CN2 Connector: Exclusive port for incremental/absolute encoder connection

  • Onboard RS232 serial port: Connect SigmaWin software for parameter upload/download, real-time running status monitoring and historical fault record reading.

4. Full Protection Functions

Complete built-in protective functions: overcurrent, DC bus overvoltage/undervoltage, power module thermal overload, encoder cable disconnection, dynamic brake overheat, abnormal input DC voltage detection. Fault codes displayed by front-panel 7-segment LED; independent dry-contact fault output for equipment safety interlock stop.

5. Environmental & Mechanical Specifications

  • Protection Class: IP20, cabinet bolt mounting only, DIN rail installation unavailable

  • Cooling Mode: Natural convection passive cooling without built-in cooling fan for compact structure

  • Ambient Condition: Operating temperature 0℃ ~ +55℃ (non-condensing); storage temperature -20℃ ~ +85℃; relative humidity 10%~90%RH without dew formation

  • Certification: CE industrial safety certified.

6. Commissioning & Replacement Instruction

  • Support automatic load inertia identification and full-range auto servo gain tuning; front-panel JOG jog function enables independent forward/reverse motor test without external controller; all fault logs stored in nonvolatile memory for maintenance troubleshooting

  • Direct interchangeable with other standard SGDC-10AJA units; no mandatory wiring rearrangement required during replacement; incompatible with Y-suffix customized models (like SGDC-XXAJAYXX) due to fixed customized firmware and exclusive CN1 definition.

  • Typical Application: Multi-axis automated assembly equipment, small CNC auxiliary axis, standard general injection molding peripheral servo axis.

7. Difference from Y-suffix Customized SGDC Models (e.g. SGDC-05AJAY16)

  1. SGDC-10AJA (Standard): Universal open firmware, all parameters fully editable, standard CN1 pinout, flexible braking parameter setting, adaptable for various general automation equipment.

  2. Y-suffix customized variant: Partial parameters factory locked, revised CN1 I/O definition, fixed braking threshold and optimized loop gain dedicated for designated OEM machine, cannot be directly replaced by standard SGDC-AJA model.
