Ultra1500 Connector Data 2-23
5 Volt Encoder Power Supply
All Ultra1500 drives supply 5V dc for the operation of the encoder. The
following table provides a description of the auxiliary encoder power supply.
Understanding the
Ultra1500 Serial Interface
The Ultra1500 includes one serial port that implements a proprietary binary
protocol for serial communication. The RS-232 interface operates at a fixed
38,400 baud, with 8 data bits, no parity, and one stop bit.
Understanding Ultra1500
Power and Ground
Connections
The Ultra1500 has three single-row, spring clamp connectors (six, four, and
three position) that provide access to the drive’s power system. Refer to Figure
2.1 on page 2-2 for the location of these terminals.
