The Geo Brick Drive brings together the intelligence and capability of the Turbo PMAC2 motion controller with the latest IGBT-based drive technology in a compact, smart 4/6/8 axis servo drive package.
The flexible nature of the Turbo PMAC2 enables the Geo Brick Drive to drive brush, brushless or AC induction 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 driving costs and setup time down.
The Geo Brick is capable of controlling up to eight axes with direct-PWM commands
