Using stepper motor without high speed output?

Recommended Posts

Hello, I have a V130 (RA-22) PLC and recently obtained a stepper motor and driver board that I was hoping to use. The RA-22 model of the V130 doesn't have high speed outputs, are the regular outputs (it has relay and analog outputs) fast enough send pulses to the stepper motor driver? Or do I need to purchase a high speed output module to use the motor?

The driver is a Lin Engineering R1025 with just step and direction inputs, there's no serial or other communication interface.

Hello,

 

The relay outputs have about 100,000 cycle lifespan - they are not recommended to be used as pulse outputs.  I would recommend switching to a unit that has high-speed outputs.

 

I would suggest one of the following part numbers if you wish to continue with the V130:

     - V130-TR20

     - V130-TR34

     - V130-TR6

     - V130-TRA22

 

The TRA22 will most closely relate to the model you have now, it just has 4 relay outputs and 4 high-speed outputs compared to 8 relay outputs that you have now.

 

Hope this helps.
