I am working on a project that involves stepper motors powered by stepper motor drivers (which is controlled with a PLC). The drivers take either a direction/pulse or CW/CCW pulse to control the speed and direction of the stepper (RORZE RD021M8).
My problem is that I am using the PLC's DO's (DA DL06) to generate the pulses, and the scan time cannot generate pulses fast enough. The drivers can accept pulses of up to 100kpps, but my plc has a scan rate of only about 2-5ms which is <500pps. My motors are spinning VERY slowly, and now need more speed! 4 axis application.
Any recommendations on how to remedy would be very appreciative. I've seen some stepper motor controllers (like Rorze RC207A) [font=Arial, Helvetica, sans-serif][font=Arial, Helvetica, sans-serif][/font][/font]on the internet but have no experience with them - if anyone has please let me know! Should I just ditch the steppers and go the route of servo / servo controller?
Thanks
