How you can use stepper motor without programmable logic controller?

Both VME-based and PLC-based stepper motor

controls have been successfully developed and

implemented. Both have proved to be reliable and easy to

maintain.

PLC-based controls have the following advantages:

• Fewer custom interface modules

• Less cabinet wiring

• Directly connects to24 vdc limit switches

• Easier to integrate motion control and interlock logic

• Safer limit switch response

VME-based controls have the following advantages:

• More complete device driver

• Less custom device driver logic

• Higher density per module (8 channel vs.4)

• Faster EPICS updates

• Auxiliary outputs included on VME module
