Hello Guys! I have a problem what I can't really solve. In factory talk view (10.0) I wanna use a momentary push button. When I start the project, and I click on it nothing happening, the button activate only when I release it. Its like there is an OSF instruction inside. I want the button activate until I push. May I use a wrong button ? Could you guy please help me with this? Thanks ahead.

Thanks for the feedback. The encoder is sew ES7C/AA. TTL/HTL encoder. So actually none of them. Its a push pull output encoder. The option card type is FR A8AP. So if i can get position then how ? I already use the inverter to read the speed of the motor. Thanks ahead.

Hello guys. I have a question, i have a mistubishi fr-a800 vfd with an encoder option card. On the motor we have an encoder. I can read back the speed with the plc with analog signal. But can i use also for, tracking the distance ? Can i set anyhow the inverter lets say after one round on the encder send some digital signal to the plc. Is there any chance to set it ? Lets say this is a conveyor, in this case its better if i put an encoder/counter on the conveyor and it will be directly connected to the plc. Thanks ahead

Hello, Thanks for the feedback. I think you wanted to writie VFD not VSD. No I don't need one more inverter. I would like to get one more safety output for my system. But in my understanding I have to attach an expansion unit to get one more. I read about more, beside connection of the EA, EB, EG, EP terminals, I have to connect the first modul's OUT terminal with the second's IN terminal. I still don't know, what should be, the inputs of the expansion modul ? Should I let the without connected ? Or should I use short cicuit between X0-COM0, and X1 - COM1, or I have to use the same inputs as used for the main module. Please guys help. Thanks ahead.

Hello guys! A would like to set up a new inverter for my existing machine. I wanna follow the recomandation about the safety wiring. The only problem is I need one more, Z safety output. I checked, there is official expansion unit, and it says I have to only connect the EA, EB, EG, and EP terminals ? Do I have to connect again the X0, COM0 ; X1, COM1 terminals, because I want actually the same inputs, just I need one more safety relay output. I attached picture about it, thanks ahead.

Hi, Do anyone knows what is the meaning of the following inverter nameplats characters ? FR-A840-00023-E2-60 Mainly the beginning with the FR-A. Thanks ahead.

Hi Guys, It might be an off topic, but I need some help, with motor sizing. I have to choose a Sew motor with a proper gearhead. I made the calculation, for the speed thats okay. But I got stuck with the loads. It will be a conveyor, the roller and the product mass altogether is 29 kg. I made the calculation for the load inertia check: Roller moment of inertia (J1); m2=mass of roller; d=diameter(mm) J1=1/8*m2*d^2*2=1/8*8*0,2^2*2= 800 * 10^-4 kgm^2 Belt and material mass = m1 = 21 kg; Belt and work moment of inertia (J2): J2=m1*( π * d)^2/4* π ^2= 2100 * 10^-4 kgm^2 J=J1+J2 = 2900 * 10^-4 kgm^2 They give me a motor with gearhead, sew eurodrive Ka37/T DRS71S4BE05. This motor performance is 0,37kW, I think its enough, but on the documentetion, I didn't find any data, about the permitted load inertia. Can anybody help me with this ? Thanks ahead.

Produced & Consumed tags
ABlearner replied to ABlearner's topic in Allen Bradley / Rockwell Automation
Thank you so much your answer. In this case do I have to download the plc program again ? Or I only have to create the tags in both PLC and done ? Thanks ahead. -
Hi guys, I have been thinking about wether can increase the numbers of produced and consumed tags, between my plc-s. Currently I have two plc it already have produced and consumed tags, but unfortunatelly soon we are running out of free tags. I read the manual and it said I can make 125 dint tags, currently we have only an array with 10 element. If I make a new one and I kinda copy it, with different names, will it be work ? Or do I have to set something else ? Can I ruin the communication with the two plcs ? THanks ahead.

Hi guys. I have a question, with HMI pages. I have to make 20 pages 3 times. Its kind of like layer in layer. At the and of the layers always there are only 2 choices. But ofc course its important the route like what the choose, and what is the order. Like we have to detect lets say first layer page2 second layer page13 third layer is page5 and then we choose the first choice. But if the order is different we have to get a different input from the choice1, like we need different address. I could do that if I make ton of pages, but its sounds crazy. A lot of permutation. (20*20*20*2) I attached a picture maybe its easier to understand if Im not explained well. I am using AB control logix PLC, with logix 5000 software. Do have someone a good and quicker idea, to solve this problem. Thanks ahead. Any idea is highly appriciated.

Hi One of my friend want use more analog output on his vfd. Its a Mitsubishi FR-A740 type. Currently the AM signal is for current, but he needs the speed and frequency too. As we saw its only one analog output is avaiable, but you guys might know better. Can someone confims our theory. Thank you.

Hello guys! I'm interesting about rfid communication. I currently using control logix and compact logix plcs, and rslogix 5000 software. I'm wondering if someone can help me with a sample project, or any documentation. Its also can be wonderful if someone can share a project with panelview if its possible. I wanna know about reading and also writing. What type of device do you guys using ? I would like to make a simple program what is contain reading and writing. Thank you ahead any help of yours.

Hi! I would like to ask your help. I want to know more about the communcation systems what allen bradley use. Most important for me, is Ethernet IP communication, Controlnet communication, Sercos (servo) communication, maybe devicenet communication. I know I can find some manulas on the web, but I thought I ask it here too, maybe you guys have some more documents which is contain more information. Every information is highly appreciated. Thank you very much guys.

Hi guys I have an control logix plc im looking for a module which is the same as 1769-ascii module. I know that module is for compact logix. Unfortunately i didnt find a good one for that purpose. Anybody can help with that ? Thanks ahead.

Hi guys! I need some help with a powerflex 525 multi speed configuring. I know I have to set the P046 parameter for 2 “DigIn TrmBlk” (source) and P047 parameter for 7 which means present frequency. This is the speed reference. I need 3 speed, so I will use Terminal 5 and Terminal 6. When both terminal is zero then 10 Hz, when terminal 5 is 1 but terminal 6 is 0 then 20 Hz and lastly if both terminal is 1 then it will be 30 Hz. I will adjust the speed with the parameters: A410, A411 and A412. Terminal 2 would be the forward and terminal 3 would be the reverse direction. I think these two can be two PLC digital output trough one-one relay. It will be counted the distance by an encoder. When it reach the target the run command will be released and the motor will be stopped with the decel time1. Also I will connect the S1 and S2 for safety. My question is do I have to connect other wires ? Also do I have to remove the jumper between terminal 11 and 1 ? Am I forget something ? Any comment would be highly appreciated. Thanks ahead.
