Product Overview

The Yaskawa SGDV-2R8A01A is a Sigma-V series single-axis AC SERVOPACK designed for compatible 200 V rotary servo motors with a maximum applicable capacity of 400 W. Its analog voltage and pulse train command interface supports position, speed, and torque control in precision industrial machinery.

The SGDV Sigma-V platform is a legacy product family primarily used for maintenance, machine recovery, and replacement of existing servo systems. Compatibility should be determined from the complete model, installed controller, motor, encoder, and machine configuration.

Main Features

• Three-phase 200–230 VAC main circuit input
• 2.8 A continuous rated output current
• Analog voltage speed and torque commands
• Pulse train positioning command support
• High-resolution Sigma-V serial encoder feedback
• 1.6 kHz speed frequency response
• Integrated Safe Torque Off through the HWBB circuit
• Automatic tuning and vibration suppression functions

Technical Specifications

Compatible System and Applications

The SGDV-2R8A01A is intended for selected Yaskawa 200 V Sigma-V rotary servo motors with a capacity of up to 400 W. Typical compatible motor families may include appropriately rated SGMAV, SGMJV, SGMEV, SGMAH, and SGMPH configurations. The complete motor suffix and encoder specification must be verified.

Typical applications include packaging machines, semiconductor equipment, inspection systems, feeders, labeling machines, small CNC mechanisms, assembly equipment, and precision positioning tables.

Maintenance and Replacement Notes

Before replacement, back up the original SERVOPACK parameters and confirm the complete SGDV-2R8A01A nameplate. Check the hardware revision, firmware, controller project, command format, pulse train specification, electronic gearing, motor model, encoder type, brake option, regenerative resistor, and cable part numbers.

Do not automatically substitute SGDV-2R8A01B, SGDV-2R8A11A, SGDV-2R8A21A, or an extended-suffix model. Their design revision, control interface, hardware options, and controller requirements may differ.
