Power Brick AC

A highly integrated and compact automation controller

PowerBrick AC

Utilising the cutting edge Power PMAC processor.

The Power Brick AC is an integrated fully scalable Machine and Motion Controller combining the brain of the cutting edge Power PMAC processor, the unsurpassed custom-designed Digital Signal Processor Gate3 ASIC and the brawns of the latest IGBT-based amplifier technology into one compact 4, 6, or 8-axis servo package driv

Additional axes are available via MACRO (high speed fibre optic network) and/or EtherCAT for a possible total of 104 (8 local + 32 MACRO + 64 EtherCAT) axes of centralized and coordinated motion control.

MATLAB®’s Simulink® with Power PMAC Facilitates user-servo code generation for Power PMAC using Simulink®’s Embedded Coder (previously known as Real-Time Workshop). The objective is to fully automate code generation for Power PMAC’s servo loop closure routines (tasks) utilising Simulink’s® control blocks.
