  1. Good Day everyone I need to use float point in arithmetic operations storing and then store them in MI's. Is there any way to do this? Here is a screen shot of my program , where i Divide 132/1270 and the result is 0. I also Attached my program Encoder y Display 6 de julio.U90
  2. I set the MI 12 to 500 and it worked fine for 1000 Hz, then i set MI to 10 kHz and it went well but the voltage decreased from +24 V to +5 V, after that i tried to set MI 20 kHz and it stuck at 10 kHz. Which is the highest frequency for these PLC's outputs ? (i assume is 1,500 Hz because it's pnp) i ask because i need to work in the range of 10 kHz to 50 kHz, Do i need to change the plc or this plc can work at this range?
  3. Hi Everybody I'm working on a project where i need a pulse sequence with a frequency of 1 kHz to 10 kHz to control a stepper motor with a drive which only needs 1 input I'm using a M91-T1-2 and i configured hardware the next way: And then i use the next ladder program to enable the output and to put the frequency's value: My question is: with this configuration i' should get 1 kHz in the output 0? or i need to do something else because i don't get any
  4. Thank you Joe T tomorrow i'll try the program and i'll post how it goes
  5. Good Day Everybody Recently i acquired the plc-m91-2-T1 and i need it for an application where i use a shaft encoder with 2000 pulses per rev (PPR) At first i tried to add both of the channels (input 0 for channel 1 and input 2 for channel 2) as shown in my program (attached) and it almost made it well for one direction (sometimes it counted 1900 of 2000 pulses) in the other direction never counted so i thought it was the speed of the counter so i reduced the pulses to 250 with a FlipFlop JK Circuit but the problem remains the same Any ideas or suggestions of how can i use the shaft encoder easier? Also i need it for both directions. Also i wanna know if there is any support in Spanish. encoder.U90
