The Gemini GT6 is a stand-alone, compact, digital stepper drive and basic motion controller in one complete package. The Gemini GT6 incorporates all of the GT digital stepper drive features such as Encoderless Stall Detect TM and ABS Damping TM (patents pending) with the flexibility of a simple, yet powerful motion controller.

The Gemini GT6 is easily configurable and programmable via RS232/485 using Compumotor’s Motion Planner TM on a PC or Pocket Motion Planner TM on a Window’s CE-based palm PC. The Gemini GT6 also offers connectivity to several field buses including Profibus, Interbus, and SERCOS.*

Similar to the digital stepper drive, the Gemini GT6 provides servo performance for the package price of a stepper system. It also allows the flexibility of an upgrade path to the Gemini GV6, due to its equivalent connectivity, programmability, and family feature set. For applications requiring stepper motor controls and basic motion control functionality, the Gemini GT6 is today’s industry technology leader.
