Connecting the DIV268N-5A Stepper Drivers to the Switching Power Supply
The stepper driver is a device that converts the step and direction signals from a breakout board to physical/electrical current to run the stepper motors. Your kit will contain between 3 and 5 DIV268N-5A Drivers depending on the kit. These Drivers use the latest TB6600 chip technology and can drive Stepper motors from 0.2Amp to 5Amp. These Drivers can run off DC power supplies between 12-48v. These instructions will cover how to connect your Stepper Drivers to the power supply(s).
AC Mains Power can kill or seriously injure
DO NOT plug in your equipment while you are working on it
Never make jumper switch changes to your Driver while it is powered up as it will permanently damage it

Required/Recommend Steps Before these instructions
These instructions will cover wiring the DIV268N-5A Stepper Driver to the 24v DC Power Supply. Do not wire the DIV268N-5A Stepper Driver to Power Supplies below 12v DC or above 48v DC as it will damage the Driver. Positions of parts and lengths of wires used are for instruction only and may vary from your actual setup and you will have to interpret/vary these instructions to meet your own needs. All parts and wiring from previous instructions have been omitted in an effort not to over complicate the images.
Wiring at the Power Supply Side
Roll out your DC wire kit so it is flat. Make sure you have a Positive (Red) and a Negative (black) wire. It is highly recommended you use the correct wire colours for each step, this will avoid confusion at a letter stage. Strip the insulation off each of the wires back 6mm (approx) and give each wire a twist to bind all the loose fibers together.
Attach fork terminals to the ends (these will connect to the Power supply). These can be crimped but soldering is preferred.
With a Philip’s head screwdriver loosen off the terminal screws 2 (labeled +V) and 5 (labeled -V). Insert the “Positive” wire (Red) to terminal 2 and the “Negative wire (Black) to terminal 5 on the power supply. Tighten screws on terminals 2 and 5.
Wiring at the Driver Side
The next step is slightly more complicated as we don’t know the actual length of wires needed to connect the DIV268N-5A Stepper Driver to the 24v DC Power Supply (as everyone’s enclosure will be different). So we are going to have to measure them by running them from the Power Supply to the DIV268N. Leave the terminals connected at the Power Supply and run the “Positive” (Red) wire to Terminal 1 (DC+ in) on the DIV268N. Allow the surplus wire to hang over the top or back or top of the DIV268N. Now do the same thing with the “Negative” (Black) wire, run it to Terminal 2 (DC- in) on the DIV268N.
With the wires now run to the DIV268N, allow another 6-10mm of wire as a stripping allowance and cut off the remainder. Put the remainder to one side as you’ll need it for wiring other components. It’s important to have a small amount of additional wire length to ensure the wires are not taught, taught wires can pull out of their terminals as your enclosure goes through it’s normal heating and cooling cycles.
Strip each wire back approx 6mm.
With a Small Flat head screwdriver loosen off the screws on terminals 1 (DC+ In) and 2 (DC- in) on the DIV268N. Insert the stripped “Positive” (Red) wire that leads from terminal 2 (24v+) on the Power Supply in to terminal 1 (DC+ in) on the DIV268N. Insert the “Negative” (Black) wire that leads from terminal 5 (24v-) on the Power Supply in to terminal 2 (DC- in) on the DIV268N. Retighten the the screws on terminals 1 (DC+ In) and 2 (DC- in) on the DIV268N.
Powering Multiple Drivers
Connecting an additional DIV268N Drive to the Power Supply can be done by using “Parallel” method of connecting units.
Using the method previously used to measure wire lengths, run a “Positive” (Red) wire from terminal 1 (DC+ in) on the first DIV268N Drive to terminal 1 (DC+ in) on the second DIV268N Drive. Remember to add a 6-10mm allowance at each of the wire. Strip each end back approx 6mm.
Now run a “Negative” (Black) wire from terminal 2 (DC- in) on the first DIV268N Drive to terminal 2 (DC- in) on the second DIV268N Drive. Remember to add a 6-10mm allowance at each of the wire. Strip each end back approx 6mm.
With a flat head screw driver loosen off terminal 1 (DC+ in) on both DIV268N Drives. Insert one stripped end of the Positive wire into terminal 1 on the first drive and the other end of the wire into terminal 1 on the second drive. Retighten both terminal 1 (DC+ In) screws on the DIV268N Drivers.
Now loosen off terminal 2 (DC- in) on both DIV268N Drives. Insert one stripped end of the Negative wire into terminal 2 on the first drive and the other end of the wire into terminal 2 on the second drive. Retighten both terminal 2 (DC- In) screws on the DIV268N Drivers.
To connect a 3rd drive repeat the instructions above.
4 or 5 DIV268N Drives will require 2 power supplies, for 4 drives this is the suggested configuration:
For 5 drives this is the suggested configuration:
It’s now time to connect the power supply to power and test the DIV268N Drives while not under load. Make sure the Power switch on the Power chassis is in the “Off” position. Insert the power lead into the chassis. Turn off your wall socket and plug the power lead in. Turn on the wall socket and turn on your power switch. The green LED on Power supply should be on and the Power LEDs on each of the DIV268N Drives should be glowing. The Activity/Error LEDs may also be illuminated (on full) this is a normal condition as there are no control signals being received and the drives are interpreting this to be an error.
Observe the unit for a minute or so to make sure nothing is wrong. Remember to turn it off when you are finished. Turn it off at the switch then the power point and unplug it from the wall. Always unplug your power supply when not in use. After turning off your power supply, please wait at least 60 seconds before turning it back on.
Power Supply powered on and power to the DIV268N Drives, alternate wiring option “Star” shown, all wiring coming off a central point.
