SGD7S Sigma-7Siec

Compact, cost-saving single axis controller/amplifier

Put complete control for a single axis of servo motion in one compact unit that conserves space in control cabinets. Sigma-7 Siec combines a Sigma-7 SERVOPACK amplifier and one axis of machine control in the space of a conventional amplifier, at a significant savings when compared to a pair of separate components.
