PA SDI-Drive Midi
Digital, compact and cost-effective
The PA SDI-Drive™ series is a digital, compact and cost-effective servo drive solution for all kind of machine tools. The PA SDI-Drive™ series offers excellent servo properties such as high dynamics, high precision, high efficiency and low heat generation.
Up to three axes in one housing saves space in the control cabinet and achieves an optimal price/performance ratio.
There is only one cable from the PA CNC system to the PA SDI-Drive™ and only one cable from one drive to the other, which makes wireing as easy as possible and reduces wireing failures to a minimum. High flexibility is provided by the availability of all conventional feedback systems.
The communication is made by the PA SDI-Bus™. This high-speed interface enables fast and jitter-free communication between the PA SDI-Drive™ and the PA CNC system.
The PA SDI-Drive Midi™ is an AC servo drive for CNC applications from the entry-level to the medium power range. The PA SDI-Drive Midi™ features two different models. The MI205™ features 2 axes with 5 amps rated current each, the MI305™ features 3 axes with 5 amps rated current each.
