well, thnx, ive done that before... i get 1000 ppr, but, in "true life" i get like 80 000 ppr because of the motor redution, a mecanic system to get 80rev / 1 motor rev. ok, now the problem is to count pulses in terms of cm or mm, i dunno how to do an IF in ladder, or the < or > conditions... something that i want would look like: 1: (start motor) if (pulses > 5000 and pulses < 5500) (stop motor) else goto 1 when i give the instruction to go 1cm ... (i measure 5000 pulses like 1cm) how can i get this? thnx :) i wish i can install ansi C in a PLC! LOL

hi there... the encoder have 1000ppr :) i get more less accurate now! :) well no multiplier (or by 1), and i get some accurate pulses in up and down counting. well, now i need to get less resolution and a way to control the motor the go near a number os pulses, im figuring out how to do this one... also how can i put the coors in outside the PLC to get the plc doing the job... :) thnx for the amazing help! :)

Hi there! :) thnx for the reply... as i said, my main problem isnt the way plcs works, but the way they show info in samples... lol well, now i can get the values from the counters... :) well, now i cant get the settings to reset the counter to zero in the card. and i have tooooo many impulses... like 80.000 per motor revolution... so... how can i get less? division will get me using real numbers.. :( well, tomorrow i will try to get any info at this... and how to reset the values in card memory to match the axis 0...

hi there... i do undestand ladder (at least with this symbols), and i can get alot things to work. the problem are the slots, and the special card... this is all new to me! so, now i think i got the card running... but i dont get the count values! here is the screen shot from the configurations... can u chenge the instructions in the to, set, dfro, etc... to a symbol ones (like melsec medoc), one of my problems in this is the samples from the datasheets... well, thnx for the help! :) i think we are almost there... i just want to count the value, to use the position to move motor up and down... thnx where can i get a sample code of that?!!? (to read with melsec), is the only program that i have! thnx in advance!

hi there, im using this code, but i still cant get it working, dunno why... so, 2 pages from my code, and 2 from the datasheet... can anyone help me what im doing wrong? i dont get how to put the vars inside the code, cuz the datasheet uses different ladder diagram... thnx for all, and let me know what im doing wrong!

hi there, can anyone help me to activate this card and put it counting the 1st a b z channels of a shaft encoder (scancon 2rm1000) well connected (worked before, but the plc got a reset...) PLC: a1SH, A1SD62(E) card in slot 3 (from 0) it's for a school project! :) thnx in advance to all
