Sigma 2 & 5 Servo Drives

Sigma II Amplifier is the ultimate servo solution for your automation needs. A single-axis controller and a variety of network interface modules can be attached to the amplifier for the utmost flexibility.

The Sigma II amplifier utilizes serial encoder technology to automatically recognize Sigma II rotary and linear servomotors.

The highly successful YASKAWA Sigma-2 (Sigma-II) Series set new standards in the Servo System field in the past. 

Technical Details

The Sigma-5 Servo Drive Series continues with this tradition of innovation. Today YASKAWA servo technology covers a broad power range and a multitude of industrial applications. Beginning with the Sigma-5 mini rated at 3.3 W up to the Sigma-5 Large Capacity motors and amplifiers with a rating of 55 kW. 

Precise, scalable and highly dynamic: YASKAWA Sigma-5 Servo Drive Series

The YASKAWA Sigma-5 Servo Drive series offers standard rotary motors as well as linear and rotary direct drives and linear sliders. This broad variety of drive systems covers all market demands with regard to compact size, high dynamics, high efficiency, low maintenance and outstanding reliability.

Sigma-5 offers precise positioning at high speed, smooth, vibration-free operation and easy start-up.

Rotary Servomotors
  • Reduced cycle time – maximum throughput
  • improved product quality
  • enhanced machine wear resistance
  • shortened initial set-up time
  • lower life cycle cost

Five Reason for Sigma-5:

The YASKAWA Sigma-5 Servo Drive series offers a wide range of well matched components with excellent performance and outstanding efficiency.

  • Comprehensive Motor and Amplifier Power Range
  • Savings through Performance Lower production costs
  • Safety Features
  • Quality and Reliability in your Production
  • Fast and simple set-up 

With a best in class frequency response of 1.6 kHz, Sigma-5 SERVOPACKS can reduce settling time to less than 4 ms. Compared to a standard system with for example 50 ms settling time, a Pick & Place unit based on Sigma-5 components can save a significant amount of money.
