The YASKAWA SGD7S-5R5A00A Servopack is a Sigma-7 single-axis AC servo drive designed for precise control of rotary or linear servo motors in modern industrial machines. It sits in the 0.75 kW power class and operates on a 200 VAC supply (single- or three-phase), giving machine builders a flexible option for medium-capacity axes that still require high-end performance.
As part of the Sigma-7 family, this model combines a 3.1 kHz speed frequency response with advanced tuning functions and safety features, delivering very short settling times, smooth motion profiles, and high reliability over long production runs.
Because it uses analog voltage or pulse train command interfaces, the SGD7S-5R5A00A is a strong choice for both new projects and retrofit applications where existing controllers output analog or pulse signals but users still want the performance benefits of the latest Sigma-7 servo platform.

3. Motion Performance and Control Capabilities
The SGD7S-5R5A00A is engineered to make axes both fast and stable:
-
High-speed control loop
A 3.1 kHz speed frequency response allows the drive to react rapidly to changes in command or load, cutting down on overshoot and reducing settling times.-
Improves throughput in repetitive pick-and-place or indexing operations.
-
Helps maintain precise tracking in contouring and synchronous motion tasks.
-
-
Analog and pulse train flexibility
The drive accepts analog voltage commands (for speed or torque control) and pulse train inputs (for position control), which means it can be connected to:-
Legacy motion controllers that only provide ±10 V analog outputs.
-
PLCs or boards with high-speed pulse outputs.
-
-
Tuning-less and enhanced autotuning
Sigma-7 Servopacks offer a tuning-less mode and improved autotuning functions that automatically set gains based on load conditions.-
Greatly reduces commissioning time.
-
Helps non-experts achieve stable performance without deep servo control knowledge.
-
-
Mechanical vibration and ripple compensation
Built-in algorithms handle typical problems such as:-
Structural resonance in lightweight frames.
-
Residual vibration after high-speed moves.
-
Torque ripple effects that can compromise surface finish or registration accuracy.
-
4. Safety, Reliability, and Compliance
Safety is baked into the SGD7S-5R5A00A design:
| Safety & Reliability Feature | Benefit |
|---|---|
| STO (Safe Torque Off) SIL 3 / PL-e CAT 3 | Provides a high level of functional safety by reliably preventing torque generation when activated. |
| Advanced Safety (SS1, SS2, SLS, etc.) | Allows speed limitation and controlled stopping strategies directly in the drive, reducing the need for extra hardware in some designs. |
| Extensive Protective Functions | Overvoltage, undervoltage, overcurrent, overload, over-temperature, encoder fault, and more to protect both drive and motor. |
| Diagnostic and Alarm Data | Drives provide status bits, fault codes, and monitoring values to PLCs/engineering tools, simplifying troubleshooting. |
| Yaskawa Proven Platform | Sigma-series drives have long field history in industrial automation, leading to high trust and low failure rates. |
These features help machine builders meet machinery safety directives, and they help end users minimize unplanned downtime in continuous-operation environments.
5. Mechanical Design and Panel Integration
The SGD7S-5R5A00A follows the familiar book-type housing of Sigma-7 single-axis Servopacks:
-
Space-saving format
The slim vertical design enables dense side-by-side installation in control cabinets—an advantage when building multi-axis systems with many 0.75 kW drives. -
Clear terminal separation
Power input, motor output, encoder feedback, control I/O, and safety/field wiring are cleanly separated, which simplifies wiring and reduces the risk of noise coupling between high-power and low-level signals. -
Thermal management
Heat is primarily discharged through the rear and heatsink area of the drive, so proper cabinet airflow or cooling should be planned. This allows the Servopack to operate within its specified temperature range for long periods. -
Industrial-grade construction
When installed in an appropriate enclosure, the drive is suitable for typical factory environments, provided humidity, dust, and temperature remain within Yaskawa limits.
6. Typical Applications for SGD7S-5R5A00A
With its 0.75 kW capacity, analog/pulse interface, and high dynamic performance, the SGD7S-5R5A00A fits a wide variety of motion tasks:
-
Packaging and converting machines
-
Film feed and sealing axes.
-
Cut-to-length systems for paper, film, or foil.
-
Rotary knives and registration rollers.
-
-
Electronics assembly and small automation
-
XY/XYZ stages for PCB or device positioning.
-
Fine pick-and-place gantries.
-
Screwdriving, dispensing, or testing stations that need precise motion at modest power levels.
-
-
Light machine tools and handling
-
Feed drives for small machining centers or drilling machines.
-
Positioning axes for jigs, fixtures, and rotary tables.
-
Handling arms moving parts between process stages.

Upgrading mechanical systems to Sigma-7 motors and drives without redesigning the entire control architecture.
-
In all these cases, the combination of 0.75 kW output, fast response, and simple analog/pulse command compatibility makes the model very convenient.
7. Integration Guidelines and Engineering Notes
When designing a system around the YASKAWA SGD7S-5R5A00A Servopack, engineers should focus on a few practical points:
-
Motor pairing
Match the Servopack with a Sigma-7 motor in the 0.75 kW range, ensuring compatibility in terms of voltage, current, encoder type, and inertia ratio. -
Power distribution and protection
-
Use appropriate circuit breakers, fuses, and contactors for the 200 VAC supply.
-
Follow Yaskawa recommendations for grounding and leakage current.
-
-
Signal integrity and EMC
-
Route encoder and low-level command cables separately from motor and mains leads.
-
Apply proper shielding and grounding to reduce noise, especially when long cables or high switching frequencies are involved.
-
-
Safety circuit design
Integrate STO and any additional safety functions with the overall machine safety concept, considering emergency stop circuits, safety relays, and safety PLCs where required. -
Commissioning workflow
-
Start with tuning-less or automatic tuning for initial setup.
-
Refine gain settings only if the application demands extra stiffness or special behavior.
-
Validate motion profiles and safety functions before production use.
-
8. Summary
