Yaskawa® Sigma 7 External Drive Package (400w-1500watts)
Overview
Alpha Tek’s Yaskawa Sigma 7 Series, complete drive system package with servo motors offers power, greater precision, better noise protection and reliability unmatched by anything in the automation industry. Better still, the 7 Series Alpha Tek Drive System suppresses vibration in motion, both from the motor’s motion components and from resonances within the machine. It detects actual vibration frequencies and cancels them out of the motion command, creating a new machine cycle that is quicker, quieter and more efficient. Furthermore, the 7 Series Alpha Tek Drive System equipped with a complete set of compensation algorithms that virtually eliminate the mechanical impediments and delivers accuracy and smoothness of movement.
Standard Features
Anti-resonance compensation counteracts the effects of a machine’s natural mechanical qualities
Ripple compensation eliminates the oscillations caused by motor cogging and other motor-based vibration effects
Friction model compensation, the 7 Series Alpha Tek Drive System automatically corrects for changes in machine operation caused by component wear and other friction effects over time.
Better Noise Protection, the 7 Series Alpha Tek Drive System servos are equipped with nine discrete filters to protect against electrical noise, vibration and resonance. The result is more reliable performance, faster response and greater accuracy despite long cable runs, noisy equipment and everyday variations in a machine’s mechanical condition.
