TERMINAL 3 +5
VOLTS
This input provides the power supply for the STEP and DIRECTION
opto-couplers. It must be supplied from the user's 5 volt logic power
supply. It provides power only to the anodes of the opto-coupler LEDs;
electrically isolating the STEP and DIRECTION inputs from the other
circuitry in the drive.
TERMINAL 4, 5, 6, 7
PHASE A, B & C, D
The motor output terminals are organized as pairs (PHASE A, B and
PHASE C, D) and drive the motor's phase windings. One motor winding
goes to PHASE A & PHASE B, the other goes to PHASE C & PHASE D.

With 6 or 8 wire motors the user has the option of connecting the motor in
high performance (parallel) or low performance (series) configuration.
Parallel operation has twice the maximum motor power output, at the
expense of greater motor and drive heating. The diagrams show both
configurations for 6 and 8 wire motors. Unused wires should not be left
exposed; insulate them to prevent damage to the control or motor.
TERMINAL 8
+10 TO 46 VDC
This is the power supply input to the CN0124. The minimum voltage is
10 VDC; the maximum is 46 VDC. The power supply may be unregulated,
however the ripple voltage must be limited to a maximum of 10% of the DC
output voltage.
