Yaskawa SGDM-04ADA Sigma II Servopack: Beyond the User Manual

MRO Electric stocks new and refurbished SGDM-04ADA Servopacks. For more information or to order a spare, please email sales@mroelectric.com or call 800-691-8511.

The Yaskawa SGDM-04ADA Servopack is high-performance, easy-to-use servo drive.  It has shortened settling time with its upgraded control algorithms that use model follow-up and vibration suppression.  It also touts high accuracy, high speed, and smooth operation that reduces motor speed ripples. The SGDM-04ADA can support a wide range of motor specifications, including 100VAC motors, single-phase from 0.03 to 0.2kW; 200VAC motors, single phase from 0.3 to 0.4kW; and 200VAC three-phase motors from 0.45 to 7.5kW.

The SGDM-04ADA also is built for easy set up and maintenance. With its online-autotuning feature, all a user needs to do is plug in and let the Servopack run. The unit’s enhanced inertia matching precision gets rid of the need for servo gain adjustment. The use of the serial encoder allows for the SGDM-04ADA to automatically sense motor capacity and type, which lets it automatically set motor parameters. The module also has built-in cumulative load factor monitoring and regenerative load ratio monitoring. It can connect to standard PC interfaces to allow for waveform display monitors, and can also be controlled through a digital operator, even without inputting speed commands.

There are a few precautions to take before putting your SGDM-04ADA into operation. Firstly, never connect a 3-phase power supply to the U, V, or W output terminals as this could result in injury or fire. It is also crucial that users never touch the power terminals on their Servopack for at least 5 minutes after turning the power Off since high voltages could still be present. One should also install the battery at either the host controller or the Servopack of the encoder. If both batteries are installed simultaneously, there will be a loop circuit between the batteries.
