Geo Brick LV Motion Controller - Delta TauGeo Brick LV Motion Controller - Delta Tau

The Geo Brick LV (Low Voltage) combines the intelligence and capability of the Turbo PMAC2 motion controller with advanced MOSFET technology, resulting in a compact, smart 4-, or 8-axis servo drive package. The flexibility of the Turbo PMAC2 enables the Geo Brick LV to drive stepper, brush, or brushless motors with unsurpassed pure digital DSP performance. 

The absence of analog signals – required for typical motion controller/drive interfacing – enables higher gains, better overall performance and tighter integration, while significantly decreasing costs and setup time. The Geo Brick LV’s embedded 32-axis Turbo PMAC2 motion controller is programmable for virtually any kind of motion control application. The built-in software PLCs allow for complete machine logic control. The Geo Brick LV supports the following types of motors: Three-Phase DC Brushless, servo, synchronous rotary/linear; DC Brush; 2-Phase Stepper. The Geo Brick LV also supports the following feedback types: Digital A Quad B; SSI; EnDat 2.2; BiSS B/C; HiperFace; Tamagawa; Panasonic; Sinusoidal; Resolver; Interferometers: Sinusoidal and Parallel; LVDTs, RVDTs, MLDts; Potentiometers.
