Sigma II series servo amplifiers from Yaskawa cover 30 W to 55 kW with input voltages of 110, 230, and 480 VAC. They can be set to torque, speed or position control with serial encoder technology. Their Sigma V series of ultra-compact rotary servomotors feature a mounted, high-resolution, absolute serial encoder for precise motion control with instantaneous peak torque to 3505 and 5G vibration resistance in a smaller package with a compact design.
