EZ-Red is a mini PLC able to drive up to 2A on its power outputs, even for inductive loads. Just for fun, I wanted to try to make a stepper motor turn.
To do this, some square waves are needed, and the EZ-Red does that. A potentiomer is connected to an analogic input to set the desired position - the PLC cycle reads the analogic value and generates the necessary waves to reach the intended position - it even makes a small velocity ramp.
But beware: a stepper motor requires a current limiter that EZ-Red does not have. This experiment is interesting because it shows the power of the internal PLC with its multitasking capabilities.
