The Gemini GT6-L8 is a standalone, compact 8A digital microstepper drive/controller with a basic motion controller and a resolution of 128,000 steps/rev, all in one complete package. The Gemini GT6 incorporates all of the GT digital stepper drive features such as Encoderless Stall Detect™ and ABS Damping™ (patented) with the flexibility of a simple yet powerful motion controller. The Gemini GT6 is easily configurable and programmable via RS232/485 using Parker's Motion Planner™ on a PC or Pocket Motion Planner™ on a Window's CE™-based palm PC. Similar to the GT digital stepper drives, the Gemini GT6 microstepper drive/controllers provide servo performance for the package price of a stepper system. It also allows the flexibility of an upgrade path to the Gemini GV6 servo platform due to its equivalent connectivity, programmability, and family feature set. For applications requiring stepper motor controls and basic motion control functionality, the Gemini GT6 microstepper drive is today's industry technology leader.

• Active Damping™, Electronic Viscosity™ and ABS Damping™
The Gemini GT6 microstepping drive/controller follows in the footsteps of Parker's ZETA stepper drive family and offers Active Damping™ (patented) and Electronic Viscosity™ (patented). The Gemini GT6 drive goes one step further with the addition of ABS Damping™ (patented). This damping feature is for speed ranges from 0 to 0.1 revs/sec. This “no fuss” feature requires no user set up and dramatically reduces settling time.

• Encoderless Stall Detect™
Encoderless Stall Detect™ allows detection of a motor stall without adding an encoder to an application. Stall conditions result from inequality of commanded velocity to actual velocity at the motor shaft, regardless of physical reason. The user will be alerted to a stall condition via LED, digital output, or via query over the communication port. Stall sensitivity can be adjusted with a single parameter.
