Connecting a Power Supply
The power supply connector is located at the upper left side of MX4660 (“CN2” in Figure 3). The power supply of
the MX4660 can be connected as illustrated in Figure 4. Although MX4660’s working voltage is 20-60 VDC, we
suggest the use of a 24-54 VDC power supply to leave room for back EMF voltage charge back during motor
deceleration. Two pins design for up to 20A applications.

Warning
(1)
Never power on the power supply before finishing all the connections and
configurations.
(2)
Make sure the two power supply leads,
﹢
&
﹣
, are correctly connected to the MX4660
power connector. Wrong connection will destroy the MX4660 and void its warranty.
(3)
Connecting a power supply with output voltage of 60VDC or up could damage the
MX4660, and void its warranty.
Connecting Stepper Motors
There are 4 stepper drive modules for the MX4660 to allow connections of up to four 2-phase stepper motors.
Because of the wide output current range from 1.41 to 6.0A for each stepper drive module, the MX4660 can
drive various stepper motors in frame sizes NEMA 17, 23, 24, and 34. You can find the 4 stepper drive module
location at CN3, CN4, CN5 and CN6 on Figure 3. These stepper motors can be 4-lead, 6-lead, or 8-lead stepper
motors.
To get the maximum torque from a stepper motor, the output current required from a stepper drive equals to
the motor phase current multiplied by 1.4. Higher output current from a stepper drive module will result the
stepper motor torque; but that also increase the motor heating. Therefore, it is recommended to set
“just-enough” output put current to get the needed torque, and as less motor heating as possible.
Connecting a 4-Lead Stepper Motor
A 4 lead motor is the easiest to connect, and its speed-torque performance depends on its motor inductance.
Refer to the wiring diagram of your stepper motor, and connect its wires to the motor connector to one of the
MX4660 stepper drive module. Refer to Figure 5 below.
