One of the most powerful multi-axis servo controller technologies for centralised machine control is the PMAC / UMAC family of our partner Delta Tau. All motion-related tasks like axis coordination (interpolation), calculation of the motion profile and the position control itself are performed by a dedicated motion control processor.
The key features are as follows:
- PMAC: PC based (PCI bus) multi axis servocontroller with +/-10V or PWM commands to the axis
- UMAC: rack based multi axis servocontroller with highest flexibility, several PCB boards with different functionality can be put together into one rack; optional multi axis CNC!
An intermediate product to the single axis controllers with integrated power stage are the new GeoBrick Drives of Delta Tau. They combine the full functionality of the Turbo PMAC2 controllers with a power stage for up to 8 axis into one housing. The input voltage ranges from 97 to 265Vac or 12 to 320Vdc at motor currents of 5 to 15Arms continuous.
The latest version is the low voltage amplifier GeoBrick-LV. The special thing about this amplifier is the 4-phase power bridge which can not only drive 3-phase servo motors but also 2-phase steppers and mixed configurations.
