Yaskawa Servo Motor Servo Drive System Improved Efficiency for Your Application

The intelligent system design of our Sigma-7 series ensures high overall efficiency and performance of your machinery and equipment. Sigma-7 servo drives are easy to implement, commission and use. Sophisticated functions like vibration suppression reduce stress on machine parts and significantly improve throughput.

Smooth integration of mandatory legal safety standards

• The STO function is implemented by default in all Sigma-7 series servo amplifiers

• Build safer machines - Sigma-7 safety modules satisfy the requirements of SIL3/PLe (Cat. 3)

• The functions SS1, SS2, SOS and SLS are standard in each safety module

• 3 different option modules are available with up to 14 safety functions

Very low heat generation

• Optimized magnetic circuit improves motor efficiency

• Improved motor efficiency reduces heat generation by about 20 %

• Ambient temperature from -5 to 55 °C (max. 60 °C with derating)
