Product Description:

Two serial connectors to simplify RS-485 multi-dropping and host communications Several analog or digital command interfaces: Indexing (absolute with the Homing feature, incremental, or
registration)10 Volt analog interface—position, velocity, or torque control Presets (from one to eight binary inputs)—torque or velocity control Quadrature encoder digital interface—electronic gearing position follower Step/Direction digital interface—position control CW/CCW (step up/step down) interfaceposition control Operating mode override—alternate movement interface Host command digital interface The ULTRA 100/200 drives host command protocol provides optional drive configuration using the drive serial communications interface. This powerful feature allows your controller to access all of the drive digital controls using sequences of ASCII characters. The protocol includes error checking to
ensure the integrity of the transmitted commands. In installations that have multiple axes, up to 32 ULTRA 100/200 drives can be addressed by a host computer. These drives communicate with the host
computer using a four-wire RS-485 serial interface. The host command protocol includes specific drive addressing, which allows the host to communicate with all the connected drives concurrently.

Product's Character:

When the drive mounted HIM is supplied, it will be connected as Adapter 1 (see Adapter in Chapter 2) and visible from the front of the drive. The HIM can be divided into two sections; Display Panel and Control Panel. The Display Panel provides a means of programming the drive and viewing the various
operating parameters. The Control Panel allows different drive functions to be controlled. Refer to Figure and the sections that follow for a description of the panels.Important: The operation of some HIM functions will depend upon drive parameter settings. The default parameter values allow full HIM
functionality.HIM OPERATION When power is first applied to the drive, the HIM will cycle through a series of displays. These displays will show drive name, HIM ID number and communication status. Upon
completion, the Status Display will be shown. This display shows the current status of the drive (i.e. “Stopped,”“Running,” etc.) or any faults that may be present (“Serial Fault,” etc.). If the HIM software is Series A version3.00
