SureStep stepper motor linear actuator, want to use with Click Plus
I am looking at a STP-LE17-2A09ADJ linear actuator to raise/lower a small container for filling. I plan to use a Click Plus PLC and would like to use the position move instruction to move the actuator to the setpoint. I am unsure of what encoder and stepper drive I would need to accomplish this. Could someone suggest a stepper driver and encoder to be able to move to position?

For the most advanced control I would go with the LW4D3070N2I1-00 drive ($173 after necessary parts), and a AMT112Q-V encoder ($148 after necessary parts), and a STP-PWR-4805 48v power supply ($183). That would get you a full closed loop system for the most accurate control.
But the cheapest drive you can use is the DM322E ($28) and a PSA-48-120 power supply ($32)
Thanks for the info
One of the beautiful things about a stepper is that you usually don't need an encoder. They certainly make a system more reliable, but if you have a light load and the motor doesn't slip, most of the time you can just use a simple drive and motor. Since you have a fairly small Nema 17 motor, you may be able to get away with a STP-DRV-4830 and just wire it up open loop to the CLICK Plus. If you want an encoder and need to run closed loop, I agree with the comment above.
A project I am doing right now I am using a Sure Step motor and driver (4545) without an encoder. I only need to run the motor at a certain speed to turn a can of paint to align it. It is not installed yet, but bench testing the setup looks promising.
The project I am doing next will need an encoder. I am planning to use STP-LE23-3H09ADJ linear actuator to lift a small empty container to be filled, then lower it back onto the conveyor. I plan to use the AMT-102-V encoder to provide a position.
Do you plan to use the encoder for position feedback into your Click, or closed loop back into the stepper?
