Yaskawa SGD7S-2R8A00A

Motion Excellence with the Yaskawa SGD7S-2R8A00A

The Yaskawa SGD7S-2R8A00A single-axis amplifier is a flagship member of the Sigma-7 servo family, purpose-built to give modern machinery the crisp, responsive motion control that today's competitive markets demand. Designed for three-phase 200 V systems and rated at 0.4 kW, this compact drive packs class-leading bandwidth and ultra-low settling times into a footprint small enough for space-conscious control panels. Whether you are fine-tuning a high-speed pick-and-place robot or coordinating a precision linear stage, the SGD7S-2R8A00A brings rock-solid positioning and silky-smooth speed control to both rotary and linear Sigma-7 motors, letting OEMs and retrofitters alike build smaller, faster, and more energy-efficient machines.

Engineered for Sub-Micron Accuracy

At the heart of every Sigma-7 amplifier lies Yaskawa's 1.6 kHz frequency-response servo loop, a leap that eliminates tracking error and overshoot. The SGD7S-2R8A00A takes full advantage of that power, pairing it with 24-bit high-resolution feedback to capture even the faintest encoder signal variations for users, that translates into sub-micron repeatability in linear applications and near-zero velocity ripple on rotary axes, opening the door to tighter tolerances in packaging, semiconductor handling, CNC machining, and 3-D printing. Integrated advanced vibration suppression algorithms further dampen resonances in lightweight frames and stiff mechanical assemblies, preserving product quality while shortening cycle times.

Effortless Integration and Future-Ready Connectivity

Instead of forcing you into a proprietary corner, the SGD7S-2R8A00A speaks your language. Native MECHATROLINK-III and EtherCAT models connect seamlessly to PLCs, IPCs, and robotic controllers, while built-in dual-port Ethernet simplifies daisy-chaining multiple axes without external switches. Safety is also baked in: Safe Torque Off (STO) is standard, and optional advanced safety over network meets cutting-edge functional-safety requirements. Quick-fit push-in connectors, one-parameter autotuning, and Yaskawa's intuitive SigmaWin+ software slash commissioning time so production can start sooner and engineering hours stay low.

Reliability You Can Measure in Decades

Servo amplifiers live and die by their uptime, and Yaskawa's MTBF statistics are among the best in the business. The SGD7S-2R8A00A employs long-life capacitors, conformal coating on critical circuits, and intelligent thermal design that keeps components cool even during aggressive acceleration. Comprehensive diagnostics record alarms, runtimes, and regenerative events, letting maintenance teams act proactively rather than reactively. The result is a servo package that keeps pressing, pickers picking, and profits flowing—shift after shift, year after year.

Fast Delivery and Total Support from MRO Electric

Production lines cannot wait for overseas lead times, and you will not have to with MRO Electric and Supply. We stock the SGD7S-2R8A00A for immediate shipment, back every unit with a no-nonsense two-year warranty, and cover standard ground freight with free shipping anywhere in the continental United States. Each amplifier is factory-tested and re-verified in our facility before leaving the dock, so it arrives ready to plug in and perform. Our applications team stands by to help with sizing, wiring, parameter setup, or emergency replacements, because your uptime is our bottom line.

Frequently Asked Questions

What motor sizes pair best with the SGD7S-2R8A00A?

It is optimized for Sigma-7 rotary motors up to 0.4 kW and corresponding linear motor coils of equal continuous-power ratings. It provides ample torque and speed overhead for most light-to-medium-duty axes.

Can the amplifier drive both linear and rotary motors without firmware changes?

Yes. To run one-touch tuning, simply select the motor type in SigmaWin+ or via the front keypad, load the appropriate motor file, and run it.

What feedback devices are supported?

The amplifier works with a 24-bit absolute encoder standard on Sigma-7 motors and can process incremental signals when retrofit constraints apply.

Does it include regenerative braking hardware?

For the 0.4 kW class, an internal regen resistor is built in; external resistors may be added if your decel profile produces higher peak energy.

How quickly can I be up and running?

Thanks to automatic notch filtering and adaptive gain search, most users achieve stable, production-grade tuning in under ten minutes.

Is Safe Torque Off certified?

STO is certified to SIL3/PLe, allowing direct connection to your safety relay or controller.

What fieldbus options are available?

MECHATROLINK-III and EtherCAT are the primary variants; PROFINET and traditional pulse-train models can be supplied on request.

What ambient conditions can it handle?

The rated operating range is 0 °C to 55 °C with 90 % non-condensing humidity and up to 1 g vibration in panel-mount orientation.

Is the unit software-upgradable?

Firmware updates are field-loadable via USB, ensuring future feature enhancements without hardware swaps.

Does MRO Electric ship the same day?

Absolutely—orders received by 4 p.m. Eastern typically leave our warehouse that evening, keeping your downtime to a minimum.
