6. CONNECTION SPECIFICATIONS
When using the Driver Only portion of the R325, use the dip switches for step
resolution and current settings.
Using the R325 as a Driver Unit Only
If using the R325 as a Driver only, be sure to connect the power supply last.
Pin 1: Connect Pin 1 to Pin 4 to use the internal +5VDC. By using the internal
+5VDC the I/O’s will no longer be optically isolated. If optical isolation is still
desired, use a separate +5VDC supply and connect the POSITIVE end of the supply
to Pin 1. The NEGATIVE end will connect with the NEGATIVE end of your pulse
generator.
Pin 2: Use a pulse generator or function generator to receive pulses into the R325.
Connect the POSTIVE end of the pulse generator to Pin 2. The NEGATIVE end will be
connected to the NEGATIVE end of the +5VDC supply if using a separate power
source. If using the internal +5VDC supply, connect the NEGATIVE end of the pulse
generator to Power GROUND.
Pin 3: To switch the direction of motor rotation, connect Pin 3 with Pin 11, Power
Ground. An open or closed connection to Power Ground will change the direction.
Pin 4: This is the internal +5VDC. Use this for testing purposes or if optical isolation
of the inputs is not desired. It can output a max of 50 mAmps.
Pin 5: To enable the drive leave this Pin open, disable the drive connect Pin 5 with
Pin 11 (Power Ground). An open or closed connection to Power Ground will enable
and disable the drive, respectively.
Pin 6: Phase A Motor Connection
Pin 7: Phase A Motor Connection
Pin 8: Phase B Motor Connection
Pin 9: Phase B Motor Connection
CAUTION: Connecting Motor
phases (A, A Bar, B, B Bar) to
the incorrect location while the
R325 is powered will cause the
board to burn. Be sure to insert motor
phases into Pins 6 through 9, in the order
of A, A Bar, B, and B Bar. It is
recommended that power is connected
last, so that all connections can be
checked before power up.
Pin 10: The Fault Output is not available for the basic R325. This feature is used on
the R325I and R325IE.
Pin 11: Connect the NEGATIVE of the Power Supply to this terminal.
Pin 12: Connect the POSITIVE of the Power Supply to this terminal. (+12 to 48VDC)
