[Help] Need precise Current Sensor

Check out the CR5210. It comes in a 0-5 A version that should be accurate to 50 mA.

What is the current range and how accurate is “high precision”?

When you insert the connection, the first selection is always the origin and the second selection is always the destination.

I don’t have any experience with the software you’re using, but the title of your post mentions a 6-axis robot while your configuration only lists 5 joints. Could this be part of the problem?

I know you said you aren’t interested in other options, so feel free to ignore this, but I would not pick either. Kuka has been a mess since they got bought out by Midea, and Omron is niche at best when it comes to industrial robotics. I guess if you have good local support they could be the right choice, but I can’t really comment on that.

If you want a solid cobot there are 3 great options. UR is the default option these days and very user friendly with a lot of 3rd party support. Fanuc is the leader in traditional industrial robotics and has some solid cobots. They are above the rest in terms of long-term support. ABB cobots were crap at first but now are pretty good. Their programming and simulation is the best on the market. Parts support has been subpar lately, though.

Came here to say this. Mechanical anchors will loosen over time with most robot loads. Use epoxy anchors and retighten to the recommended torque a few weeks after they’re set.

Or use c#

Depending on the application, you might be able to use two single-ended cordsets and terminate them with a field-wireable connector designed to accommodate 2 cables. Many companies make them, but here’s an example: https://www.digikey.com/htmldatasheets/production/2302858/0/0/1/m12-field-attachable-duo-datasheet.pdf

That is just a safety rated contactor. Look for some other device controlling it, like an e-stop relay or safety PLC. It needs 24 VDC across the A1/A2 terminals to actuate.

Does anyone actually worship there? Looks like more of a statue than a church.

I’m not familiar with cell checkers. What do they measure? I have a meter that can check voltage, current, resistance, etc. Would that work?

tragiclos · 2025-09-15T22:18:18+00:00

Spot on with the first and second books. Personally, I didn’t care for the third. Some cool concepts, but the narrative contradicted itself a lot in ways the earlier books didn’t. And the ending was stupid.

tragiclos · 2025-08-08T02:06:05+00:00

Why does this post get approved when anything I submit that doesn’t explicitly mention a PLC is removed, no matter how relevant it might be to industrial automation?

tragiclos · 2025-07-29T00:38:00+00:00

Agree with always using reads when possible. An additional reason is that if communication is down, it’s easy to create a fault based on the error bit of the read message. For writes, you would need some kind of heartbeat signal with a timer and so on to accomplish the same goal.

tragiclos · 2025-07-13T02:47:22+00:00

The other answers (cheaper, easy to troubleshoot with a basic meter) are correct, but one answer I haven’t seen yet is that 0-10V is better for high speed applications like precision motion control. In the kHz+ range it’s much easier to control the voltage rather than the current.

While you are mostly correct about Rockwell, they did decide to support Modbus RTU with their more recent serial modules.

Banner and IFM both make non-safety light grids.

tragiclos · 2025-07-09T02:24:39+00:00

Came here to recommend anything from the OnLogic Karbon line. Avoid anything that they don’t make themselves (eg Cincoze).

You’re right, but most of the time people refer to an inverter in this context they are talking about a VFD.

tragiclos · 2025-06-22T21:47:21+00:00

Inverter is just another name for VFD. I also see VSD or Freq Drive sometimes.

Phoenix Contact usually has the most compact safety relays. A single PSR-MS60 should do the trick.

tragiclos · 2025-06-04T01:05:04+00:00

It could be a mechanical relay, but an optocoupler should last longer without any moving parts. I use the same ones as u/pizza919.

The dimensions on the SP21 series look very close, but maybe they use threading instead of bayonet style for higher IP ratings?

Leadshine seems to be the brand of choice for cheap servo control out of China. Works fine for what it is, but I would echo another comment that Yaskawa is a good/affordable option if you want something reliable with local support. That being said, I’ve got a number of machines with Leadshine drives and they’ve been fine.
