Description
Product Overview
The SINFONIA SDD-N-20A4K00-1-7 is an AC servo driver manufactured by SHINKO ELECTRIC / SINFONIA TECHNOLOGY. Industry equipment listings identify this exact model as a 4 kW AC servo DD driver, and repair-service references classify it as a motor driver / AC servo driver.
This model is intended for industrial motion-control applications where a servo amplifier is used to control a compatible motor and provide controlled acceleration, deceleration, speed, and positioning.
The same part number appears in multiple equipment-service and resale references, making the complete model number important when sourcing a replacement.

Key Features
- Original SHINKO / SINFONIA industrial servo drive.
- Exact model number: SDD-N-20A4K00-1-7.
- 4 kW class AC servo driver.
- Associated with SDD-N series motor-control equipment.
- Suitable for maintenance and replacement of older industrial motion-control systems.
- Useful as a spare for equipment where the original SDD-N driver is no longer readily available.
- Compact identification by complete model number makes equipment matching straightforward.
Typical Applications
This servo driver can be found in industrial motion-control equipment requiring controlled operation of a compatible servo or direct-drive motor.
Typical applications include:
- Industrial automation machinery
- Precision positioning equipment
- Semiconductor manufacturing equipment
- Factory automation systems
- Servo motor control
- Motor replacement and maintenance
- Legacy equipment repair
Because the exact motor and machine configuration cannot be determined from the driver model alone, the original machine documentation should be checked before installation.
Installation & Configuration
Before replacing an existing driver, compare the complete nameplate and wiring configuration.
- Confirm the model number SDD-N-20A4K00-1-7.
- Check the driver revision and connector arrangement.
- Verify the motor model and rated capacity.
- Confirm the original machine’s input power requirements.
- Inspect power, motor, encoder/feedback, and control connectors.
- Follow proper electrical isolation and discharge procedures.
- Install the driver using the original mounting arrangement.
- Restore wiring exactly according to the equipment schematic.
- Confirm motor parameters and control settings before operation.
- Perform a low-speed test before returning the machine to normal production.
Do not assume that another SDD-N model with a similar capacity can be substituted directly. Servo drivers must be matched to the motor, feedback system, and machine controller.
Inspection & Testing
For a used unit, recommended inspection includes:
- Nameplate and model-number verification
- Exterior and terminal inspection
- Connector inspection
- PCB inspection for corrosion or contamination
- Inspection for burnt components or abnormal discoloration
- Cooling fan and ventilation inspection, where fitted
- Power-up test with suitable equipment
- Servo enable / alarm check
- Motor-control test with a compatible motor
- Feedback and communication verification where applicable
One Korean industrial equipment supplier lists this exact model as a used SINFONIA AC servo driver and states that its unit was tested and confirmed operational. This is evidence for that particular unit, not a guarantee that every used unit is tested or functional.
Maintenance Notes
Keep the ventilation openings clean and avoid operating the driver in environments with excessive dust, moisture, oil mist, or conductive contamination.
For long-term storage:
- Keep the unit in a dry environment.
- Protect connectors from dust and oxidation.
- Use anti-static packaging when handling the PCB/electronic assemblies.
- Avoid unnecessary power cycling during storage.
- Record the complete model and revision before installation.
For older servo equipment, replacement planning is especially important because the motor, amplifier, feedback device, and host controller may have been configured as a matched system.
Frequently Asked Questions
Q: What is SINFONIA SDD-N-20A4K00-1-7?
A: It is an SHINKO / SINFONIA AC servo driver used for industrial motor-control applications.
Q: Is this a 4 kW servo driver?
A: Yes. Multiple listings for the exact model identify the SDD-N-20A4K00-1-7 as a 4 kW AC servo / DD driver.
Q: Is SDD-N-20A4K00-1-7 a motor?
A: No. It is the servo driver/amplifier. The compatible motor must be selected according to the original machine configuration.
Q: Can I replace another SDD-N model with this unit?
A: Not automatically. Voltage, current, motor compatibility, feedback, control signals, and parameter configuration should all be checked before substitution.
Q: Is the exact input voltage confirmed?
A: A reliable public technical datasheet for the exact SDD-N-20A4K00-1-7 configuration was not located, so the input voltage should be verified from the physical nameplate or original equipment documentation.
