The Gemini GT is the digital stepper drive member of the Gemini Family. The Gemini GT is easily configurable and programmable via RS232/485 using Compumotor’s Motion PlannerTM on a PC or Pocket Motion PlannerTM on a Window’s CETM-based palm PC. The Gemini GT is an alternative to a digital servo drive. With breakthrough techniques such as Encoderless Stall DetectTM and ABS dampingTM (patented), the Gemini GT provides servo like performance with the lower motor price of a stepper system. With the same connectivity, configurations, and family feature set as the Gemini GV, the Gemini GT allows for an easy upgrade path to the Gemini GV digital servo drive.

Active DampingTM, Electronic ViscosityTM and ABS DampingTM The Gemini GT follows in the footsteps of Compumotor’s ZETA drive family and offers Active DampingTM (patented) and Electronic ViscosityTM (patented). The Gemini GT goes one step further with ABS DampingTM (patented). This damping feature is for speed ranges from 0 to 0.1 revs/sec. This “nofuss” feature requires no user set up and dramatically reduces settling time. 

Encoderless Stall DetectTM Encoderless Stall DetectTM 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.
