1. Full Model Code Definition

• SGDC: Compact multi-axis shared DC-bus SERVOPACK series (differentiated from AC mains input SGDB series)

• 20: Rated continuous output power: 2.0kW (2.68HP)

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

• J: Circuit design dedicated for common shared DC bus power supply

• A: Base standard hardware platform

• -F: Built-in cooling fan (forced air cooling; standard SGDC-20AJA uses natural convection without fan)

• Y16: OEM customized factory firmware variant, fixed parameter preset, modified CN1 I/O pin definition & special factory setting locked by original program; cannot restore to universal standard firmware

2. Electrical Rating Specifications

• Main DC bus input: DC280V～DC330V, rated input current: 10.4A

• 3-phase PWM output: 0~230VAC, rated continuous output current: 19A, 300% short-time overload (max 3s peak)

• Control power terminal is fully isolated from main DC bus circuit

• Built-in dynamic braking circuit; external brake resistor available for frequent high-cycle deceleration

• Cooling system: built-in DC fan forced cooling (unique for -F suffix) for continuous heavy-load operation

3. Control Modes & Interface Description

1. Pulse position control: differential / open-collector CW/CCW or A/B quadrature pulse input; partial electronic gear ratio range locked by Y16 OEM setting

2. ±10VDC analog speed / torque control: gain & offset preset fixed values from factory customization

3. MECHATROLINK-I fieldbus hardware reserved onboard, bus function pre-set per Y16 specification

Terminals

• CN1: Customized digital I/O pin assignment (different from standard SGDC-20AJA definition due to Y16 modification, fixed OEM I/O logic)

• CN2: Standard encoder dedicated connector for incremental/absolute encoder

• RS232 port: Supports SigmaWin parameter upload/download, partial core parameters are read-only and locked for Y16 customized version

4. Full Protection Functions

5. Environmental & Mechanical Parameters

• Protection grade: IP20, cabinet panel installation only, DIN rail mounting unavailable

• Operating ambient temperature: 0℃~+55℃ non-condensing; storage temperature: -20℃~+85℃; humidity:10~90%RH no dew

• Net weight: approx 4.54kg, CE certified industrial standard

6. Replacement & Application Notes

1. Interchange restriction: SGDC-20AJA-FY16 can only be replaced with identical FY16 variant; incompatible with standard SGDC-20AJA / SGDC-20AJA-F without Y16 suffix (different firmware & I/O definition)

2. Auto inertia identification & JOG test function available, partial auto-tuning parameters locked by Y16 OEM program

3. Typical application: Special customized multi-axis automation equipment, dedicated OEM production lines, customized peripheral servo for precision machinery
