I want to add to this video information that is missing. First you must run 24v (no less) to the driver side for step/pulse. Anything less they will not rotate. For optimal performance the servos like 48v 20 amp supplies. For the dip switches if you plan to machine with them you need no less than 40,000 steps, preferably 51,200 to optimize torque or you will not have enough torque and trigger missed steps. For Hertz (pulse frequency) control settings these are rated at 250,000hz so you need a setting equivalent or higher. I used 400,000 in my control and anything less they will barely rotate. Anyone who wants to program theirs via rs232 I have the JMC software application to access the internal settings and I am willing to share with you just ask. As far as those connectors go they are junk and unreliable. Even if you solder connections they can come loose. There is a fix. Take some hot glue and glue the wires to the connector which will also make it water proof and prevent them from pulling out from vibration or movement.
What do you call hertz control ? The normal Step/dir interface is reference to 250kHz max in the datasheet. No official way the 400kHz you mention would work. Also with such a high "micro stepping" (40 000 or more) it's normal than you need a lot of step per revolution and so a high number of step pulse to turn just a bit the motor. Assuming that one "full" step make the motor do a complete rotation (from what I have understand here --> ruclips.net/video/A5QgvOsf7nI/видео.html )the problem with such a high "micro stepping" will be that for example if my machine use 10mm pitch ball screw and I use 40 000 "micro step" my machine would only go up to 250 000/40 000 = 6.25revolution per second *10mm pitch = 62.5mm/s *60 = 3750mm/min witch is rather slow. Maybe I'm wrong with the 1 "full" step per revolution, but if this drive really need a high "micro step" to have the full torque that would be a little disappointing ! EDIT www.upload.sorotec.de/doku/manuals/DS_iHSV57en_181023_Soro.pdf The datasheet said that's it's the number of pulse per revolution "Pulses per revolution of the iHSV57 can be configured via DIP switch S1-S4 or by the tuning software" so my calculation seems right
Geekoid , These are not steppers nor do they react like them. Your thoughts apply to steppers only. AC servos function much differently and the dip switches for better explanation have nothing to do with steps. In fact these motors shouldn’t even have dip switches but the fact is they do and the function is not like a stepper. They are meant for different internal programs. They do offer a stepper model and yes these are often confused. Stepper model is IHSS57 Instead of IHSV57. By the way these servos are plenty strong enough to power a bench mill.
@@glennedward2201 Okay, I was in fact talking about the ac servo version you mentioned. So on this version the micro stepping I choose will not only act as normal and so reduce the speed and increase the accuracy for a given square wave frequency but also change something in the internal program that make it have more torque. Am I right ?
I'm just setting these up myself, and I have had success with the opposite. I'm using UCCNC AXBB-E controller, where I can set the frequency from 100kHz to 400kHz. Anything over 100kHz does NOT work for me, at all. At 100kHz, and setting the dip switches to either 800 pulses per rev, or 1600 pulses per rev, I get amazing motion. See my video here testing them out: ruclips.net/video/voVWMctjNIw/видео.html
It’s bad practice to tin the ends. When you screw them into the terminals everything will be fine for the moment but after a couple months they will come lose. You better use nothing or ferrules.
if i look at the wiring at the end you conect pul+ DIR+ and ENA+ of the same wire? in the maniul it tels my Remark： (1) t1: ENA must be ahead of DIR by at least 5μ s. Usually, ENA+ and ENA- are NC (not connected). (2) t2: DIR must be ahead of PUL active edge by 6μ s to ensure correct direction; (3) t3: Pulse width not less than 2.5μ s; (4) t4: Low level width not less than 2.5μ s. but i dont now how to set it up corectly only way i can think of is for ENA+ to be powerd when i pouwer the machine
You are a little bit wrong about the interface.. the position and alarm lines are outputs from the servo. (Notice the optocouplers in the picture are mirrored) They can pull a line to gnd, if this line is connected to a pullup resistor. (Do not connect directly positive voltage without a risistor to it.. it will be like a short) The error line will connent the signal to gnd if there’s an error, the position line is connected to gnd while the servo is driving to its position.

thanks god!!! finally I found someone explaning how to build with this JMC motors... I bought 3 of them but I don't know how to put all together... :S
I have 3 and none work
Smae situation, but waiting in buying it. Would you recomend it as well?
You don't have a link to where you got the wires ? Also what are those green connections from ?
is it normal that green LED flashes, if only DC+ and DC- is connected to the servo?

Geekoid , your pulse frequency needs to be 250k or higher.

I want to buy the same motors, i ll use DDCS v4.1 , can you tell me where and how you connect the encoders ?
It’s bad practice to tin the ends. When you screw them into the terminals everything will be fine for the moment but after a couple months they will come lose.
You better use nothing or ferrules.
hey welches controller board & welche steuerungssoftware hast du verwendet?
You have 7 lead cable. What happened to other 3 leads?
if i look at the wiring at the end you conect pul+ DIR+ and ENA+ of the same wire? in the maniul it tels my
Remark：
(1) t1: ENA must be ahead of DIR by at least 5μ s. Usually, ENA+ and ENA- are NC
(not connected).
(2) t2: DIR must be ahead of PUL active edge by 6μ s to ensure correct direction;
(3) t3: Pulse width not less than 2.5μ s;
(4) t4: Low level width not less than 2.5μ s.
but i dont now how to set it up corectly only way i can think of is for ENA+ to be powerd when i pouwer the machine
Дякую!

what motor controller are you using? I have to buy one...
I’m using Centeoid Acorn and it works well.
hello sir.i have one clay extruder with me ready.If you want to purchase you can contact me on +91 9041714676.My email id sahiblatour@gmail.com
Welche Kabel hast Du verwendet?
