Connecting the Power
The R325 requires a supply voltage between 15-48 VDC. First, connect the positive
end of the power supply to positive terminal (Pin 12), and then connect the negative
of the power supply to the Ground (Pin 11) on the R325.
WARNING! Be careful not to reverse the polarity from the power supply
to the driver. Reversing the connection will destroy your driver and void
the warranty.
Connecting the Motor
WARNING! Make sure the power is OFF when connecting or
disconnecting motors from the R325. Damage will occur if the
power is being supplied.
Please refer to your motor documentation for wiring color code.
Connect the corresponding Phase from the motor to the proper pin on the R325.

Phase A- Pin 7
Phase B Pin 8
Phase B- Pin 9
Using the R325
When using the R325 in Step/Direction mode, insure that there are no jumpers on
JP1 and proceed to Section 7 – Basic Step and Direction Operation.
Using the R325 with more than 5V
You can choose to supply the optos with the R325’s internal 5V supply by jumping
pins 1 to 4. But if you choose to use more than 5V, for example, a 24V supply and
the step pulse train is also a 0 to 24V low-high signal, please use the following
recommended resistor to limit the current to 10 mAmps. Note: no resistor will be
needed on the actual opto supply line, pin 1.
