2. Basic Electrical Specifications

2.1 Power Ratings

Main circuit input: 3-phase AC200V~230V ±10%, 50/60Hz; single-phase 200V also available with derated output
Rated continuous output per axis: 18.6A RMS; peak transient output per axis: 56A (max 3 seconds overload)
Total rated capacity: Dual 3kW, total 6kW integrated in single chassis
Control power supply: Independent AC200V auxiliary input or external DC24V ±10V external power option
Cooling structure: Built-in internal cooling fan forced air cooling; IP20 protection grade; net weight approx 3.9kg.

2.2 Control Hardware & Interface

  1. CN1 (50pin standard control connector): Dual-axis shared control terminal, receive CNC pulse command/±10V analog speed reference, servo enable, fault output, digital IN/OUT for both Axis1 & Axis2, differential/open-collector pulse input, max pulse frequency 500kpps, electronic gear ratio programmable separately per axis.

  2. CN2 / CN3 Dual encoder ports: CN2 for Axis1 serial encoder, CN3 for Axis2 serial encoder; compatible 17bit incremental serial encoder, optional battery-powered absolute encoder for CNC zero-point retention.

  3. Built-in RS485 serial communication: Connect SigmaWin+ parameter software for parameter upload/download, auto-tuning, real-time axis monitoring, fault history check.

  4. Independent dual-axis closed-loop control: Axis1 and Axis2 operate fully independently, separate parameter group, separate overcurrent/overload/overheat protection for each channel.

2.3 Working Control Modes (Parameter configurable)

  1. Position Control: Pulse command from CNC controller (differential line driver / open collector input), widely used for CNC feed axis positioning

  2. Analog Speed Control: ±10VDC analog voltage from CNC spindle/axis board for continuous speed regulation

  3. Analog Torque Control: ±10VDC torque reference for tension control or special CNC rigid tapping application

3. Installation & Environmental Requirements

Operating ambient temperature: 0℃ ~ +55℃; storage temperature: −20℃ ~ +70℃
Operating humidity ≤90%RH non-condensing; installation environment free of corrosive gas, conductive dust, oil mist, explosive vapor.
Mount vertical on solid metal mounting plate; top clearance ≥40mm, left/right clearance ≥30mm for fan heat dissipation; install away from high-power contactor, transformer to reduce EMI interference.

4. Wiring Safety & Wiring Rules

Important Safety Warning

Cut all AC input power and wait minimum 15 minutes after power-off for internal DC bus capacitor full discharge before any wiring or cover removal to prevent electric shock hazard.
  1. Main power terminals R/S/T: Connect 3-phase AC200~230V main input power; PE protective ground terminal must reliably connect equipment earth ground.

  2. Axis1 motor terminals U1/V1/W1 → 3kW Axis1 servo motor power leads; Axis2 U2/V2/W2 → Axis2 servo motor power leads, strictly no cross connection between two axes.

  3. CN2 encoder cable → Axis1 motor encoder; CN3 encoder cable → Axis2 motor encoder; all signal cables use shielded wire with single-side grounding for shielding layer.

  4. CN1 control cable connect CNC system control signal per standard SGDK-AEA pin definition (no customized pinout for suffix A version).

    Separate high-current power cable and low-voltage control/encoder cable routing to avoid electromagnetic interference causing position drift or random servo alarm.

5. Commissioning Step-by-Step Guide

  1. Pre-power check: Double-check main power, dual motor power, dual encoder, CN1 control wiring correctness, confirm no short circuit between terminals.

  2. Power on the unit, complete internal self-diagnosis; confirm no hardware fault alarm codes displayed on front panel LED.

  3. Execute Axis1 no-load auto-tuning first: automatically identify motor resistance, inductance, optimize servo gain parameters; repeat same auto-tuning operation for Axis2 separately.

  4. Set control mode and related motion parameters (electronic gear ratio, speed limit, acceleration/deceleration value) respectively for Axis1 & Axis2 per CNC machine specification.

  5. Low-speed jog test without mechanical load for each axis individually, verify smooth rotation without abnormal noise/vibration; after jog test pass, install mechanical load and complete formal CNC linkage running test.

6. Standard Alarm Codes & Troubleshooting Guide

表格
Alarm CodeFault DescriptionRoot Cause & Solution
A.10Overcurrent per axisMotor winding short, U/V/W wiring wrong, IGBT module damage; power off inspect cable insulation and power module
A.20Encoder fault (Axis1/Axis2)Loose CN2/CN3 connector, broken encoder wire, encoder damage; replace defective cable
A.30Main circuit undervoltageAC input voltage insufficient, unstable power supply, loose main terminal screw
A.40Overheat protectionLong-time continuous overload, fan failure, poor cabinet ventilation; clean fan dust or improve cooling
A.02EEPROM parameter errorInternal memory data corruption; reset factory parameter and redo auto-tuning
After fault root cause eliminated, cut full power supply for 3min then restart servo to clear alarm; repeated same alarm needs professional circuit board maintenance.

7. Periodic Maintenance Specification

  • Every 3 months: Clean cooling fan and internal accumulated dust inside chassis, check terminal screw tightness to avoid loose contact overheating failure.

  • Every 6 months: Check encoder cable aging and shielding grounding status, inspect fan running noise for abnormal wear.

  • Long-term storage over 12 months: Pre-power on no-load running for 40min before formal machine installation to activate internal capacitor.

8. Manual Supplementary Note

Official standard English base manual document No: SIEPS80000006 (SGDK-AEA general series manual covers SGDK-3030AEA standard specification), no exclusive separate manual for SGDK-3030AEA dual 3kW model; custom modified suffix model needs OEM wiring document, this model suffix A is standard version fully following general SGDK-AEA manual standard pin definition.
