Description

1. Model Definition

  • SGDM: Σ-II standard servo drive series

  • 08: Rated matched motor power 0.75kW (750W)

  • A: Single/3-phase AC200~230V main power input specification

  • DA: Universal dual command model, supporting pulse position + ±10VDC analog speed/torque control, three control modes switchable via parameter setting

Matching standard servo motors: SGMAH-08A / SGMPH-08A series 750W, rated speed 3000rpm with 20-bit serial incremental encoder.

2. Electrical Ratings

  1. Power Supply: Single-phase or Three-phase AC 200~230V, 50/60Hz; control power supplied together with main circuit power

  2. Output Rating: Continuous rated output current 5.7A, peak instantaneous overload current 13.9A (300% rated for short-time startup load)

  3. Output: 3-phase AC 0~230V, output frequency 0~300Hz, IGBT PWM sine-wave drive

  4. Encoder Interface: CN2 port for standard 20-bit serial incremental encoder; optional absolute serial encoder with backup battery

  5. Net weight: 1.7kg, natural air cooling, IP10 protection grade

3. Control Interfaces

CN1 (Control Signal Terminal Block)

  • Position command: Differential / Open-collector pulse input, max input frequency 500kpps, programmable electronic gear ratio

  • Speed & Torque command: ±10VDC analog voltage input

  • Built-in multi-point digital input/output for servo enable, fault reset, alarm output, zero-speed signal etc.

CN2 (Encoder Feedback Port)

Standard serial encoder wiring for motor position feedback, fixed pin definition same as original factory manual.

CN3 (RS232 Debug Port)

Connect to SigmaWin software for parameter read/write, auto gain tuning, running status monitoring and fault record check.

4. Core Functions

  1. Three control modes freely switchable: Position / Speed / Torque by parameter setup

  2. Automatic motor parameter identification & load adaptive auto-tuning function

  3. Built-in multiple protection functions: Overcurrent, overvoltage, undervoltage, overload, overspeed, encoder break, overheat, wiring error protection; fault code displayed on front LED panel

  4. Vibration suppression filter to eliminate mechanical resonance.

5. Environmental & Installation Spec

  • Operating ambient temperature: 0°C ~ +55°C; storage temperature: -20°C ~ +85°C

  • Working humidity ≤90%RH, no condensation; avoid corrosive gas, dust and liquid splash

  • Vertical DIN rail/base mounting; reserve ≥25mm upper/lower space for heat dissipation

  • Separate high-power motor cables and low-voltage control/encoder cables; single-end shield grounding for signal wires to reduce EMI.

6. Wiring & Commissioning Notes

  1. Cut off input power and wait ≥10min for DC bus capacitor discharge before wiring maintenance to prevent electric shock.

  2. Main AC input to L1/L2/L3 terminals; U/V/W connect three motor power lines; PE terminal reliable equipment grounding.

  3. Complete wiring inspection first, power on for self-check; no-load jog test after eliminating startup alarms, finish auto-tuning before formal load running.

7. Typical Application

CNC small feed axes, packaging machinery, automated feeding equipment, small indexing rotary fixtures, semiconductor automation equipment.
