5. Options de remplacement (Discontinued Model Selection)
6. Remplacement de la même série (Compatible with original MECHATROLINK-II): SGDV-5R4D05A (optional variant, spare part replacement only)
7. New-generation Σ7 series recommendation: SGD7S-120D10A (400V 1.5kW, MECHATROLINK III; different bus protocol, PLC program and cables require modification)
8. Alternatives nationales: Inovance IS650, HCFA X3 400V-class 1.5kW bus servo. Motor parameters and communication need re-commissioning.
9. Installation & Directives d'entretien
10. High voltage remains in capacitors after power-off. Attends au moins 5 minutes after power cut before opening the cover. Confirm the Charge lamp is extinguished.
11. Vertically mount inside control cabinet; reserve ventilation space top and bottom to avoid overheating caused by dust accumulation.
12. Motor power cable and encoder cable must be shielded with single-end grounding to reduce bus interference.
13. Regenerative circuit: Use internal resistor for normal operation. For frequent emergency stop / high deceleration loads, connect external braking resistor and modify resistor rating in parameter Pn600.
14. Common Alarms (SGDV Σ-V)

A.100: Surintensité / Heat sink overheat

A.400: Surtension (Excessive deceleration, insufficient regenerative resistance)

A.410: Sous-tension du circuit principal

A.C90: Drive overheating

A.810 / A.820: MECHATROLINK-II communication fault. Check bus wiring, station number, termination resistor.

UN.020: Parameter corruption. Restore factory defaults and reconfigure motor parameters.

8. Recommended Matching Motor

SGMGV-13D (400V, 1.5kW, inertie moyenne, most commonly matched motor)

8. Alarm History & Function Menu Fn (Non-storable parameters, record reference)

Fn000: View Alarm History

Fn005: Write Parameters to ROM (Mandatory after parameter modification!)

Fn006: Servo JOG Operation

Fn009: Factory Initialization (Restore all parameters to factory default)

⚠️Important: After Fn009 initialization, motor code Pn001 is cleared; motor identification must be re-run!

9. Sauvegarde & Restore Procedures (Papier + Software Dual Backup)

1) Sauvegarde

1. Allumer, Servo OFF; connect via SigmaWin+
2. Read all parameters and save project file (.wpj)
3. Record table parameters; log electronic gear ratio, station number and termination resistor status
4. Export alarm history via Fn000

2) Restaurer (Replacement of SGDV-5R4D01A drive)

1. Allumer, run Fn009 factory reset first
2. Write Pn001 motor code, power cycle
3. Import backed-up full parameters
4. Set MECHATROLINK station number and termination resistor
5. Execute Fn005 to save parameters to ROM
6. JOG test, confirm no alarms and normal bus communication
7. Remarques
8. SGDV-5R4D01A is MECHATROLINK-II version. Do not confuse with pulse-type SGDV. Wrong Pn000 control mode will trigger A.810 communication alarm.
9. 400V unit: DC24V control supply, 3-phase 380~480V main circuit. Power sequence: Apply 24V control power first, then main circuit power.
10. For drive replacement: SW1 rotary station number is hardware-prioritized. Software station number setting does not take effect.
11. When external regenerative resistor is installed, Pn600/Pn601 must be updated. Otherwise A.400 overvoltage alarm may occur and damage regenerative circuit.
