    RMS, AND 1.732 FOR 3 PHASE

    I was wondering if anyone knew why with single phase, we use the constant .707, which is the reciprocal of the square root of 2. And for 3 phase we use the constant 1.732, which is the square root of 3, but not the reciprocal value. I am not a student, btw, doing homework. I've just forgotten...

    working on multifingered gripper?

    We use three fingered grippers in 6 places on one of our robots, what exactly are you wanting to know? Basically way overkill. We're using a very expensive robot as a pick and place.

    Sourcing vs Sinking outputs and CE

    I don't believe sourcing is a requirement for machine tools unless this is very recent. I have to many okumas and mazaks that are fairly new for this to be the case. Everyone of those machines I've worked on were sinking.

    Sourcing vs Sinking outputs and CE

    Troubleshooting wise, I believe sourcing is much better, Really depends on the customer, what do their people like and already have in place? Mixing is the biggest problem I've seen.

    PLC Password

    Micrologix uses nothing but numbers for a password, But I appriciate it. By the way, I did get it. The password, I mean. The software is Commlite 32. it monitors the initial talk between your terminal, and the plc. Bad side? It has to be Windows 98 or 95.

    rs linx

    You can't go straight from Linx to the processor. It sees them but that is all. You have to have 5 or 500 open (depending on which you're hooked up to of course), go to comms, and do a who active go online. Should hook you up.

    STEP7 Instalation Problem

    Also, the siemens drivers will want to take precedence over everything else in your laptop. If you have Logix or something like that on there, they'll be fighting all the time.At my work, we don't even mess with that anymore, seperate comuters for diff apps.

    Capacitor Plagues - Premature Electrolytic Capacitor Failure

    Electrolytic Caps are notorious for failing. I read somewhere (don't recall where now) 70%+ of all power supply failures are due to to electrolytic caps. Just look at the tolerance values written on them and you see why.

    thread277-4196 / Integrating PLC and SCADA

    I have some experience using a line with a bunch of AB plc's and a bunch of siemens S7 plcs. And scada to communicate (whatever that is). I'm a lead electrician in a bearing manufacturing facility, and use S5, S7, Logix 5, Logix 500, and Logix 5000 to troubleshoot and some cases, some simple...

    Optical encoder selection for a motor control project.

    I agree with "itsmoked". For speed and direction, a tach would be the way to go (though a resolver needs to be used in some circumstances, like a tach and encoder combined). The only time I've ever seen an encoder used for something to do with speed was with displaying RPM's and it used the "Z"...

    PLC Password

    Hi, my first post as I'm new, There was a previous post with someone needing a "backdoor" for a siemens S7 plc, and one person replied with a way to get into AB's plc's. He said to use "comm view 32". And gave a procedure, too. Anyone familiar with this program? I googled it and came up with...
