Stepper Motor Control with MicroLogix 1200

Are there any modules available for the Micrologix 1200 that perform stepper motor control? Is there a standard protocol to use with normal outputs?

thx,

You need to use the Pulse train outputs.
More info is in the programming manual for that specific range of processors.
No card as far as I know, considering that there is built in functionality in the block part of the PLC.

I have used a Micrologix 1000 for stepper motor control like this but it is easier to use a dedicated stepper control board with digital inputs and read back the pulses to the HSC input.

We generally use a stepper motor drive.

Depending on the make/model, you can usually set them up to make specific moves/velocities or follow pulse trains.

Some will take encoder feedback to do position verification (not usually closed loop control but the ability to see if the step motor went where commanded).

This has the advantage of letting the PLC output low power signals to drive a higher power step motor. The drive has all the power components to drive the bigger motor.

Also, most drives do something called microstepping which allows to you to have finer position control than the 1.8 deg step angle built into most step motors.
