Yaskawa Sigma-7 ServoPacks Single Axis
Sigma-7 ServoPacks
Yaskawa equips each SERVOPACK with a suite of software commissioning and tuning tools, designed to achieve full functioning right out of the box. This superior performance continues in spite of all the vibration, resonance, friction and noise that a modern automated machine can dish out.
Get rid of effects that steal away performance
Unwanted mechanical effects rob a servo system of the quick, smooth and precise movement you need. Yaskawa SERVOPACKs are equipped with suppression features that automatically eliminate harmful artifacts.
Vibration
Machine vibrations are eliminated by Yaskawa Vibration Suppression, which samples your equipment’s natural oscillations and uses compensating frequencies to cancel them out.
Ripples
Motor cogging effects are removed by Ripple Compensation, an especially important effect for systems that require minimum settling time and exceptionally precise positioning.
Resonance
Sigma-7 amplifiers have twice as many anti-resonance filters to more effectively repress a servo system’s natural medium-frequency resonances.
Friction
Coulomb friction and viscosity-related variables are effectively addressed by Friction Model Compensation, which effectively elicits smooth start-up action in low speed or high rigidity machines.
Electromagnetic interference
The number of interference filters has been increased by 225% to counteract losses caused by data dropouts, EMI interference and artifacts from long cable runs.
