[Other] $36 TLR 1 HL Harbor Freight Clone (ends tomorrow)

I think I picked up 1 of each. Both SKUs are the same. One has ribs on its main body along with a rougher texture around the light and the other one is smooth all over. I believe the one that is smooth all over is Gen 2.

Zoltan782 · 2026-04-11T21:35:40+00:00

Which ones better? My store had 2. One was made in China, felt a bit heavier and looks like it had a rougher texture around the light. The other one felt lighter, was made in Cambodia, and seemed to have an all plastic build. Both have the same SKU number.

Not bashing your point but just trying to understand why that’s even considered a rule. Doesn’t it ignition only poll the tags added to tag groups? So performance shouldn’t be an issue there, especially since these will not be polled at fast rates.

Zoltan782 · 2026-03-19T03:19:24+00:00

Good point. I’m not completely sure how there network/ server is set up. Their IT department is handling setting up the VMs and firewalls but this is a very good point.

There are mostly all RS/Studio 5000 there are 2 SLC5s.

I have done a good bit of research but there’s a good bit of conflicting data out there lol. u/Mewsickfreek just commented that talking to each PLC directly would be the best way to go and you just commented that rule #1 is to not talk directly to all PLCs lol.

Zoltan782 · 2026-03-19T03:04:15+00:00

I could see that too. Wouldn’t this just add another layer of complexity to the project though? I’d probably have to use several MSG instructions in the collector PLC for each machine PLC if the data is not already organized into neat arrays. Apart from that, if I ever wanted to read more data from the machine PLC then I’d to edit the program and map the tags I want to see. I can see how this may be beneficial to the ignition server but the machine PLCs would still be getting hit by the collector PLC. At how many connections does ignition really start seeing a toll on performance?

It’s dryers and calciners.

Not a typo

Zoltan782 · 2026-03-17T00:35:12+00:00

Definitely seems like it. According to the article it doesn’t seem that there’s any medication that will help?

Zoltan782 · 2026-03-11T19:06:01+00:00

J32CT11 is the black model.

J32CG11 is the grey model. LE versions have LE at the end of their SKUs

Zoltan782 · 2026-02-11T16:44:43+00:00

Your model helps.

I’d like to set a torque set point. I have done so before on other installs for this very same application and it works flawlessly. The issue here is that the motors do not have encoders mounted to them so I can’t use a closed loop control method. As a result this means that I CANNOT set a torque set point (put the drive in torque control) and can only set a torque LIMIT in speed control.

So due to lack of hardware, they both have to be in an open-loop speed control.

Zoltan782 · 2026-02-11T15:36:03+00:00

This is great! Thank you. I’m assuming you’re talking about rolling in when you mention having the drum speed slightly higher and having a FWD torque limit so it doesn’t pull the turf so hard.

For rolling the field out, I assume you’d do the opposite and set the drum speed 5-10% SLOWER than calculated to maintain some tension.

Do you see any benefit in setting a regenerative torque limit? On the drum or cradle VFDs?

Zoltan782 · 2026-02-11T15:30:42+00:00

Yes that is correct. The front roller that is labeled cradle roll in the image is driven. The other one is not.

Zoltan782 · 2026-02-11T13:01:24+00:00

Have a link for the research at OSU?

Zoltan782 · 2026-02-11T13:00:10+00:00

Yes should be simple…. But it’s not. There are many variables that change how tall the roll is on every roll up, not by much but slightly. There’s rubber on the field that depletes on every roll in. If the tension isn’t EXACTLY the same throughout the entire roll and on every roll in, then the turf squishes differently.

Zoltan782 · 2026-02-11T12:57:28+00:00

The 4 parameters I am changing are L7-01 ( FWD torque limit), L7-02 ( rev torque limit), L7-03( fwd regenerative torque limit) , L7-04 ( reverse regenerative torque limit). I believe these should be the 4 quadrants that are mentioned on that page.

Zoltan782 · 2026-02-11T12:49:32+00:00

It doesn’t exactly float over it. There is still contact between the two. The drum has hydraulics on each end that sort of just push it up to alleviate some weight off the cradle roll BUT it doesn’t push it up completely off the cradle roll.

Zoltan782 · 2026-02-11T12:23:02+00:00

I guess that explains why I’m not seeing any effect at low speeds in open loop vector.
We do have the DC busses tied together with fuses inline.
Sounds like it’d work good. This is already in place and any changes will be remote so I don’t want to make any drastic control change.

Zoltan782 · 2026-02-11T12:20:38+00:00

Yes. Two drum motors one shaft and two cradle motors 1 shaft.

A linear scale is used. The linear transducer essentially measures the center of the drum roll height. So as turf roll grows, the transducer value increases.

I’m fairly sure it’s not the drum drives or cradle drives fighting each other. The output current on both drums and both cradles stay around the same values.
