Folks, I'm new here and I'm hoping to get some help from our community here.
Here I goes. I have a stepper motor driver for hobbyist from sparkfun (easydriver).
I also have a Keyence plc transistor output to send pulse to my driver.
Now the problem is that I have used npn for all my previous projects. It seems like the easydriver is not a npn device.
On the easydriver is 3 inputs, "step", "dir" and "gnd". Let's just focus on step and gnd.
For npn connection, rightfully plc output common is connected to negative 0v. +24v to step pin of easydriver. Gnd of easydriver connect to Plc pulse output. This to me is seems more like a pull signal by plc rather than feeding signal to easydriver to drive motor.
Should the flow be plc output common to +24v. 0v to Gnd of easydriver. Plc pulse output to step pin of easydriver. This circuit seems more right to me because signal is coming out from plc pulse output. Is this circuit correct and is this circuit called pnp?
Seriously, any help is really appreciated. Thanks!
