Hello, I am using 2 proximity switches to count and determ a drum speed installed on a gear teeth system. I considered count measurement by the HSC and the extended HSC instruction that gives elapsed time between counts. I want to use the instruction CTRL_HSC_EXT to calculate the number of pulses in the HSC with predefined period whit this formula which I think is good, I also read it in the forum that CTRL_HSC_EXT gives elapsed time between counts., I 've created MYBD data block. Formula: (EdgeCount*MesurementFaktor)/Periodtime is your rotational speed.
Somewhere I am doing wrong !please see attached! Thank you in advance! Attachmentspeed.pdf (68 Downloads) |
