The UI215GA intelligent step motor driver has a maximum current output of 1.25A/phase (2.5A total).
Therefore, only the motors listed below are recommended for use with the UI215GA. These motors are
recommended due to their winding characteristics. The use of any other motors with the UI215GA driver
may damage the driver, the step motor or both.
Motors recommended for use with the UI215GA Intelligent Driver
BINARY CODED DECIMAL (BCD) FORMAT
The Index Data (number of steps in an index mode move) is input to the UI215GA Intelligent
Driver in a Binary Coded Decimal (BCD) format. In the BCD format, four data lines are used to
represent each decimal digit (1000's, 100's, 10's and l's). The UI215GA has a maximum of 9,999
steps (4 digits), therefore, 16 data lines are necessary to have complete flexibility when selecting the
number of steps in an Index move. Similarly, 4 data lines are required for the Running Speed inputs.
By referring to the table below, the correct "ON"/"OFF" combinations can be determined to com-
plete the desired length of move. See the wiring example shown on page 21 for details on selecting a
move length of 6,798 steps.

NOTE: A data line is considered "ON" when there is a connection between it and ground.
