jblkiller Posted April 4, 2018 Report Share Posted April 4, 2018 I have a Durant counter that I want replace by a V350-35-T38 because I need 4 preset. In the setup of Durant counter we have to enter count scale. I don't see how put this number in visilogic software. My encoder is a quadrature 100 ppi.

Isakovic Posted April 5, 2018 Report Share Posted April 5, 2018 You set up encoder in "Hardware configuration". There you select for high speed inputs "shaft encoder" x2 or x4 and assign memory location to it (use ML or DW instead of MI because it has bigger range). Note that if you select x2 you will have a value of 200 for full turn, and if you select x4 you will have a value of 400 per turn. It will also increment in one and decrement in other direction. All other logic you will have to work out in ladder. How many impulses per mm, presets... All the best, 1 Link to comment Share on other sites More sharing options...

jblkiller Posted June 1, 2018 Author Report Share Posted June 1, 2018 How configure the HMI to see the speed in Feet/min.? In the hardware configuration I setup I1 to Frequency measurement 1000mSec in ML 1. (I0 is configurated Shaft encoder X4). How convert frequency to feet/min.? When the encoder turn one time is 1 feet. Encoder is a 100ppr, Thanks Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted June 3, 2018 MVP 2023 Report Share Posted June 3, 2018 You've set your frequency sample period to 1 second, which is good. 100 Hz = 1 ft/sec * 60 sec/min Cancelling the units and bringing the 100 to the other side of the equation - 1 Hz = (1 * 60) / 100 Multiply your frequency by 60 and then divide by 100. In that order. Joe T. 1 Link to comment Share on other sites More sharing options...
jblkiller Posted June 4, 2018 Author Report Share Posted June 4, 2018 I have 5 preset for this cable winder. 1) Slow down before stop 2) Stop the line at XX feet 3) Send a output pulse to the printer at 1/4 of length for cable identification 4) Send a output pulse to the printer at 1/2 of length for cable identification 5) Send a output pulse to the printer at 3/4 of length for cable identification Can I use the compare box (greater equal) to compare the length with a preset and output on when he reach the preset? The operator run the line at 400 to 1000ft/min. The plc will be fast enough to send a output at the good preset of length? My program has 25 rungs and when I test and go online with my laptop I see on SI0: 2. Link to comment Share on other sites More sharing options...
