how to invert rotation of a bipolar stepper motor

[Depi01]

Hello, i have this very simple program that starts a stepper motor. I want to be able to invert the rotation of the motor... how can i do it?

The motor is connected to a MyRIO 1900.

Thank you

Hi Depi,

with just one pin/DO you can only control the speed, but not the direction…

Read the manual of your stepper motor!

You need the manual. The motor should have information on it. When you search for the manufacturer and serial number, you might get the manual.

ok, here you have the manual

How to reverse rotation direction

[Depi01]

I'm not understanding how to invert the rotation without changing the link of cables.... can u give me an example of code?

Hi depi,

your motor comes with 6 wires according to your datasheet, you don't need to rewire them to have the motor turn in the other direction!

You need to output signals/current to the right wires to define the direction. For this you probably need more than just one digital output…

ok thank you, so i have to link black green red and blu cables to vcc and GND. yellow and white cables to a digital input?

Hi depi,

I would link YEL/WHI to either GND or Vcc and switch the other wires/windings as needed…
