SANYO DENKI Develops Compact, Lightweight 2-Axis Integrated AC Servo Amplifier with Eco- and User-Friendly Features
March 27, 2025
SANYO DENKI CO., LTD. has expanded its lineup of the SANMOTION G AC servo systems by adding a 2-axis integrated AC servo amplifier that comes in the smallest size in the industry.(1)
This amplifier drives two servo motors with a single unit, contributing to downsizing, weight reduction, and energy savings for your equipment. Additionally, it features user-friendly functions, such as displaying the motion of 2 axes on a single screen of the setup software.(2)
It is ideal for machine tools, robots, semiconductor manufacturing equipment, and general industrial machinery.

Features
- Eco-Friendly -
1. Compact and Lightweight
Compared to using two single-axis servo amplifiers, the installation footprint has been reduced by 38%(3) and the weight has been made 19% lighter,(3) allowing for more efficient use of space within the equipment.
2. Reduced Wiring
Compared to using two single-axis servo amplifiers,(4) the wiring has been reduced by 35%, reducing the wiring work.
3. Energy Savings
Compared to using two single-axis servo amplifiers, the energy loss in the servo amplifier has been reduced by 18%.(5)
The regenerative energy generated during the deceleration of one axis can be effectively reused to power the other axis, contributing to energy savings in the equipment and supporting the SDGs.

- User-Friendly -
1. Easy 2-Axis Coordinated Motion
Two axes can be operated in sync with reduced wiring.
Also, the amplifier features 2-axis programmable operation that enables high-precision 2-axis positioning with simple commands.
These make it easy to check the operation for enhanced convenience.
2. Easy Setup
The setup software can display the motion of two axes on a single screen.
This simplifies setup tasks such as equipment startup and adjustments, improving maintainability.
