The Sigma II Amplifier is the ultimate servo solution for your automation needs. A single platform covers 30 watts to 55 kW and input voltages of 110, 230 and 480 VAC. The Sigma II amplifier can be set to torque, speed, or position control. 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. Advanced algorithms provide high performance tuning and suppression of machine resonance. A built-in keypad and serial port allow easy set-up and monitoring of the servo system. SigmaWin and SigmaWin Plus software can be used to capture torque, speed, and command references and SigmaWin Plus Professional can perform FFT and machine simulations.

The FSP Sigma is an expansion of the Sigma II Series servo system. FSP stands for Flexible ServoPack and is built on the proven Sigma II SGDH amplifier power platform. This amplifier provides built-in position control for simple indexing applications, electronic gearing, and cam profile following, in addition to the standard analog and pulse input of the Sigma II Series. The FSP positioning mode employs Yaskawa's latest generation of real-time adaptive tuning, which dramatically reduces following error and settling time. FlexWorks, the FSP setup software, features single-button auto-tuning, digital oscilloscope, FFT mechanical analysis, and wizard set-up for amplifier mode, units, and I/O. Yaskawa serial encoder feedback is standard providing customers with automatic motor recognition for combinations with all Sigma II rotary and linear servomotors. An optional model provides the capability to drive non-Yaskawa servomotors with industry standard A-B quadrature feedback. For further information on non-Yaskawa motors supported by Yaskawa, see the Special Purpose Motor Program.

The LEGEND SGDG amplifier is an economical solution for torque-control applications which utilize the speed and position loop of the SMC-4000 controller. The LEGEND-MC SMC-3010 can be attached to the amplifier for single-axis positioning applications. Plug-and-play cables for Sigma II linear and rotary servomotors and SMC-4000 controllers make start-up and installation easy. Serial encoder technology allows the amplifier to automatically recognize the motor. The LEGEND amplifier is available in four sizes from 100 watts to 1.5 kW with input voltage from 90-253 VAC.

The Sigma Mini amplifier is an ultra compact all-digital amplifier designed for use with Sigma Mini motors. The Sigma Mini amplifier is available in 10 or 20 watts with input voltage of 24 VDC. Options include an analog input version for torque or speed control or a pulse input version for position control.
