ISD300, THE INTELLIGENT SERVODRIVE ISD300 offers, at a low price, the wide bandwidth typical of analogue architecture coupled with the easiness of customization and regulation typical of digital architecture.


The dedicated microcontroller, the serial line (RS232 or multi-drop RS485) and the user interface on Personal Computer local or remote on the WEB under WINDOWS NT allow to easily set parameters of control loops and to watch quantities of interest: currents, speed, temperature, as with an oscilloscope.
