Hawk - Digital Servo Drive in ExtrIQ Family

Hawk - Highly Compact and Intelligent Digital Servo Drive
Highly Compact and Intelligent Digital Servo Drive: Hawk

The Hawk drive is a unique digital servo drive that combines high power density and intelligence in an ultra compact package, delivering up to 45 Amps continuous current. It operates in extreme environmental conditions. The Hawk drive is a member of Elmo's ExtrIQ servo drives family with characteristics and functionality that are identical to those of all ExtrIQ family members. The Hawk takes Elmo one step further in incorporating high efficiency and ultra-compact power density, delivering up to 75 Amps continuous current.

It suits all motion control applications, especially those where servo performance and compactness are important. The Hawk servo drive is PCB-mounted that provides top performance, intelligence and networking capabilities, all within a high level programming environment.

  • The Hawk drive is powered by a single DC bus of 11 VDC –195 VDC (three voltage ranges), with built-in smart control to supply back-up capabilities.
  • The Hawk servo drive is a powerful servo drive that can withstand extended environmental conditions

This servo drive features sinusoidal full vector control as well as trapezoidal and DC motor commutation methods. It has an auxiliary feedback port for ECAM, follower, dual loop and pulse-and-direction applications. Digital and analog ports are also available. When combined with its programming flexibility, wide variety of feedbacks and CANopen networking, the Hawk digital servo drive is a compelling solution.
