The Gemini Series

Closing the Loop Between Servo and Stepper Technology, Compumotor Announces Gemini: A family of compact digital drives and drive/controllers perfect for your servo and stepper application needs.

Low-to-mid power servo applications can now be solved with the Gemini GV, the GV6 or the GV6K. They all offer drive features such as digital tuning, digital notch filters, and up to 14.7 kW of peak power. The Gemini GV6 goes one step further and offers basic motion control features such as programmable motion profiles, sequencing, registration, conditional statements, and I/O. In addition to all the control features of the Gemini drive/controller, the GV6K (servo) offers the 6K's Ethernet connectivity, expandable I/O, multitasking, and enhanced position following. The packages comes complete with our wizards-based Motion PlannerTM software, a graphical programming language that drastically reduces the amount of time the end-user will be required to spend setting up the GV6K.

In addition to the high-performance servo systems, the Gemini family also includes the highest performing stepper drive systems in the industry today. The Gemini GT, GT6, and GT6K have performance enhancing features such as Encoderless Stall DetectTM, ABS dampingTM, and up to 8 Amps of continuous current. The Gemini GT6 also offers basic motion control such as programmable motion, sequencing, registration, conditional statements, and I/O. A stepper drive with built-in 6K Controller, the GT6K offers all the digital drive features of the Gemini GT6 stepper drive as well as the 6K's Ethernet connectivity, expandable I/O, multitasking and enhanced position following. As with the GV6K, the GT6K comes complete with our wizards-based Motion PlannerTM software to drastically reduce programming time. Since the Gemini GT (stepper) and Gemini GV (servo) have equivalent interface, connectivity, and controller options, the Gemini allows an unprecedented opportunity to mix and match servo and stepper technology.

Let the Gemini family solve your application and you will always be able to apply the appropriate motor technology for each axis of motion. The Gemini GT offers an easy upgrade path to the GV if the needs of your application change. Each member of the Gemini family is configurable/programmable via RS-232/485 using Compumotorís Motion PlannerTM on a PC or Pocket Motion PlannerTM on a palm PC. You need to look no further. The Gemini offers all of the power levels, connectivity, performance features, and control levels to solve all of your motion control needs.
