Host Communications
The following graphic illustrates how host communications provides optional drive configuration using a
drive’s serial communications interface. This powerful feature allows your controller to access all of the
drive’s digital parameters and functions. The protocol includes error checking to ensure the integrity of the
transmitted commands.
In installations that have multiple axes, a host computer can address up to 32 Ultra3000 or Ultra5000
drives. These drives communicate with the host computer using a 4-wire RS-485 or 2-wire RS-232
interface.
