Sigma 7 Mechatrolink III Servopack, 400W, SGD7S-2R8A20A

The SGD7S is a single-axis Servo amplifier from Yaskawa’s flagship Sigma 7 range of servo systems. SGD7S-⬚⬚⬚A20A range of Servopacks come with a Mechatrolink 3 interface and are available in sizes ranging from 50W to 15kW.

When designing the Sigma 7 range Yaskawa focused on three main development goals:

• Fast and easy to understand set-up / commissioning –  This is achieved with the help of presets in the amplifier software which allows for the system to be commissioned without the need to learn the full expansive range of parameters beforehand.
• Outstanding reliability – With over 12 million servo systems already in the field Yaskawa’s Sigma drives are tried and tested to work no matter what is thrown at them. The latest iteration of Sigma servo systems come with a host of new improvements to help increase uptime which reducing maintenance and servicing costs.
•  Increased efficiency and production output – Sigma 7 motors come with a more optimised magnetic circuit which helps improve motor efficiency and reduces the thermal buildup meaning that additional cooling is unnecessary.
