Of all the approved Hickory servo systems: Yaskawa Sigma 7, Glentek Gamma series, Estun Summa, Leadshine EL7 and EL8, Inovance SV660N, and Delta ASDA-B3-E and the ASDA-B3A-E, Teknic Clearpath EtherCat Which systems are going to be the most affordable? I need around 1.5 Kw give or take, and minimum 5 Nm or more, just to give a rough idea of what size I need, so if one of the manufacturers doesn't make anything bigger than 1kw that would exclude them, etc. I'll be using external linear encoders, but as I understand using the encoder expansion board for Hickory will handle those (so, the more affordable servo system doesn't need to have it's own external linear encoder input, as I understand.)
While understanding that high-end performance and low-end price usually don't coincide...
1) Which systems are going to be on the expensive end? (I can save myself the time and effort of shopping those systems)
2) Which systems are generally going to be the most affordable?
3) Do any of the affordable systems have limitations that would make them not-great for making injection molds with fine surface finishes?
4) I love the AcornSix price, but Pulse/Direction flows only a fraction of the information that EtherCat/Hickory can which is important for fine mold surface finishes. I'm thinking "the lowest-cost EtherCat sero and Hickory will be better than the highest-quality Pulse/Dir servo and AcornSix". Is this an overstatement? Also, how much might I regret making the leap from AcornSix to Hickory but doing it with lower cost servos. How big of a difference will I see in mold finishes with more affordable servos vs. premium performance servos (all other factors being equal, machine quality, etc)
I had an AcornSix budget, but I want to make the leap to Hickory, I'm looking reduce impact to the budget while also not making a servo system choice I'll wish I hadn't.
Thanks!

Alright, I'm not gonna speak on the mold making specific stuff but here is what I know:floridamachineshop wrote: ↑Fri Oct 04, 2024 11:53 am Of all the approved Hickory servo systems: Yaskawa Sigma 7, Glentek Gamma series, Estun Summa, Leadshine EL7 and EL8, Inovance SV660N, and Delta ASDA-B3-E and the ASDA-B3A-E, Teknic Clearpath EtherCat Which systems are going to be the most affordable?

Assuming you need at least 5 nm continuous torque excludes the ClearPaths.
1 and 2) Yaskawa Sigma 7 and Glentek Gamma are expected to be most expensive. Delta B3/B3A and Estun Summa also have great performance and cost less. Below those in price should be Innovance SV660N and Leadshine EL7 or EL8. Leadshine EL8 and Estun Summa are the two lower cost options that can do built in closed loop control with the linear encoder systems. We recommend using the Hickory for closing the loop with scale feedback anyway.
3) I'm not a machinist so I'm not gonna say anything specific about surface finish but the main difference between the less and more affordable systems is the ease of tuning when you need more precision in position control. Yaskawa's autotune is fantastic and we generally find that only one slight tweak is needed afterwards to get unbelievably low position error. We have gotten some of the lower cost options to come close to or match those results but some might need more tweaking after autotune than others.
4) One advantage of Hickory over AcornSix is that the Hickory reads the encoder counts directly from the drives so the whole system is closed loop before the linear encoders mounted to the axes come into play. I don't know what influence that has on surface finish.

Re: Most Affordable Hickory Servo Systems
I have a friend that runs Innovance SV660N ; on a video, the performance looked quite impressive. From what i remember it was about 200-250usd per axis.
delta b3 is about 360 per axis, other options are above that

Re: Most Affordable Hickory Servo Systems
To me, affordable includes my time. If this is your first conversion with Centroid, I'd choose one of the drive and motor packages that they sell. Having schematics, manuals that are readable, and REAL technical support are well worth their cost vs. the false economy of Alibaba.
Cheers,

Re: Most Affordable Hickory Servo Systems
A nice benefit of ethercat is that the wiring is pretty much plug and play. As pretty much all sets come with premade cables.
