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...

Omran has one, will go to 600 hz I think. I'll have to get the model # and stuff tomorrow if you're intrested.

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.

I think i would change the gears myself or ratio, so to speak. Just an idea.

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.

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.

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.

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.

RS Logix 500 for SLC 500 and Micrologix 1000, 1200, 1500. RS Logix 5 is for PLC 5. RS Logix 5000 for control logix series of contollers.

Use to be a place in KC called Slaughter that made specialized relay test equipment, don't know if they're still around or not.

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.

whenn you open the program, does it look Right? Documentation, I/O, the ladder or ladders itself, ect.?

I fyour PLC's are S5 units from Seimens, and the battery is marginal, it will reload the eprom module data wich may be different from you present.

Running windows 98, With PCMK card ( I assume it handles both DH-485 (Logix 500) and DH+ (logix 5) you have to you have to reconfigure the driver anytime you go from one to they other. Nodes are another thing you have to check. Also, when congiguring the drivers, it will want to kow what slot...

Thats awesome. I haven't tried it, but diffently sounds good. I'll let you know if it works. Thanks

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.

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...

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"...

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...
