Description

1. Model Coding Definition

  • SGDC: Shared common DC-bus compact SERVOPACK (multi-axis shared DC power architecture, different from AC input SGDB series)

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

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

  • J: Internal circuit dedicated for common DC-bus power supply connection

  • A: Standard universal factory firmware, no OEM parameter lock, full parameter editable

  • -F: Custom factory variant with built-in cooling fan (standard SGDC-20AJA uses natural convection cooling without fan; F=fan equipped for high-load continuous operation)

Matching Servo Motor: SGMG-20A2AB (2.0kW, 200V-class Sigma-I motor; compatible with 8192P/R incremental encoder & battery-backup absolute encoder)

2. Key Electrical Specifications

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

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

  • Independent separated control power terminal, isolated from main DC bus circuit

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

  • Cooling mode: Forced air cooling by internal built-in fan (unique for suffix -F model vs natural cooling standard version)

3. Supported Control Modes

Three configurable working modes via parameter setup:

  1. Pulse Position Control: Accept open-collector / differential line-driver pulse (CW/CCW dual-pulse or A/B quadrature pulse); full adjustable electronic gear ratio

  2. Analog Speed / Torque Control: External ±10VDC reference signal input; gain, offset and filter parameters fully programmable

  3. Reserved hardware interface for MECHATROLINK-I fieldbus, enable via parameter setting as required

Interface Terminals

  • CN1: Universal digital I/O port (Servo ON, fault reset, positioning complete output, dry-contact fault relay output)

  • CN2: Exclusive encoder connection socket for incremental / absolute encoder

  • RS232 debug port: Connect SigmaWin software for parameter upload/download, real-time status monitoring & fault history reading

4. Built-in Protection Functions

Overcurrent, DC bus overvoltage/undervoltage, power module overheat, continuous overload, encoder wire break, brake overheat, abnormal auxiliary power protection; fault codes displayed on front LED panel with independent relay alarm output for machine interlock stop.

5. Environmental & Mechanical Data

  • Protection class: IP20, cabinet panel mounting only (DIN rail mounting unavailable)

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

  • Weight: approx 4.54kg; CE industrial safety certified

6. Application & Replacement Note

  • Support auto inertia identification & auto gain tuning; front-panel JOG function for manual motor forward/reverse test without external controller

  • SGDC-20AJA-F cannot directly interchange with standard SGDC-20AJA: Cooling structure differs; only replaceable with same -F suffix fan-equipped model

  • Typical use: Multi-axis automated assembly equipment, CNC auxiliary axis, plastic injection peripheral servo system
