7. CONNECTION SPECIFICATIONS
To begin using the R325I, first determine how you will operate the unit: Simple
Controller/Driver or Driver Only. When using the Controller/Driver, insure that
the jumper is located on Pin 7 & 8 on JP1 and that switches 8, 9, and 10 are
in the OFF position, setup must be made with an RS485 connection and
communication can take place using Windows HyperTerminal. When using the Driver
Only portion of the R325I, first remove the jumper located on JP1, use the dip
switches for step resolution and current settings.
Using the R325I as a Driver Unit Only
If using the R325I as a Driver only, be sure to connect the power supply last.
Pin 1: Connect Pin 1 to Pin 4 to use the internal +5 VDC. By using the internal +5
VDC the I/O’s will no longer be optically isolated. If optical isolation is still desired,
use a separate +5 VDC 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 R325I.
Connect the POSTIVE end of the pulse generator to Pin 2. The NEGATIVE end will be
connected to the NEGATIVE end of the +5 VDC supply if using a separate power
source. If using the internal +5 VDC 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 +5 VDC. Use this for testing purposes or if optical
isolation of the I/O’s is not desired.
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
R325I 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 used in driver only mode. Sits high.
Pin 11: Connect the NEGATIVE of the Power Supply to this terminal.
Pin 12: Connect the POSITIVE of the Power Supply to this terminal. (+15 to 48VDC)
