Posted 21 Sep 2018 Hello All I am new to PLC programming , i have a question regarding omron PLC and High speed counters. I am using Cp1H-XA model plc . I connected HSC port 0 with a encoder and i was able to get the speed of the encoder using PRV2 instruction. Now i am trying to connect the second encoder from the servo motor that i am using to HSC port 1. I am getting the PV signal using PRV instruction . Is there a way to calculate the speed of the servo encoder connected the HSC port 1 using PRV command , since i can't use the PRV2 command for the servo encoder . Thanks in advance .

Posted 29 Sep 2018 I don't understand... you can use PRV2 for the HSC0. Why can't you use it on the HSC1 as well? Share this post Link to post Share on other sites
Posted 2 Oct 2018 (edited) Because the PRV2 works only with HSC0. The PRV may be used to measure the speed programmatically, with certain limitations in resolution and update period. Edited 2 Oct 2018 by Sergei Troizky Share this post Link to post Share on other sites
