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.
