Main Connector
The R701P uses a 2-piece modular main connector. The connector is split into two pieces: Terminals
1 through 6 (power supply and motor leads) and Terminals 7 through 12 (control interface). Each can
be removed separately by pulling the connector body upwards and off of the mating header pins on
the R701P. You may need to remove the connectors to mount the R701P properly to a chassis.
8. MOTOR CONNECTIONS
Step Motors have 4, 6, or 8 wires. To better understand how to connect your step motor with your
R701P Driver, follow the Figures below for the corresponding motor. NOTE: The dots indicate the
starting position of the wires when wound.
4 Lead Wire Motor Connection
Connect one set of windings to the A terminals. Connect the other set of windings to the B terminals.
If the set of windings is unclear, take a pair of wires; use an ohmmeter to check for continuity. When
you find the first two wires that have continuity, connect it to the A terminals. Connect the other two
to the B terminals.
Figure 5.1: 4 Lead Wire Motor Connection
6 Lead Wire Motor Connection (Half Winding)
Six wire motors can be wound in two ways: Half Winding and Full Winding. Six wire motors contain
a center tap on each of the two windings. For a half-winding connection, the center tap and one end
of the wires are used.
