Ultra3000 Connector Data 2-51
5V Auxiliary Encoder Power Supply
All Ultra3000 drives supply 5V dc for the operation of an auxiliary
encoder. The following table provides a description of the auxiliary
encoder power supply.
Understanding the Serial
Interface
The Ultra3000 includes one serial port that implements the standard
NRZ asynchronous serial format, and supports RS-232, RS-422, and
RS-485 communication standards.
Standard baud rates include 1,200, 2,400, 4,800, 9,600, 19,200, and
38,400 baud. Data lengths of 7 and 8 bits are supported. Parity settings
include odd, even, and none.
The connector pinout dedicates separate pins for the RS-232 and
RS-422/ RS-485 signals, so that the communication standard can be
changed by just using a different cable. Refer to Figure 2.55 for the
serial interface configuration.

IMPORTANT
The internal 5V dc power supply has a resettable
fuse that opens at 3 amps and automatically resets
itself when the current falls below 3 amps. There are
no internal fuses requiring replacement.
