Leadshine ES-D808 with Masso = No movement

[rk-engineering]

Hello everyone,

Let me introduce myself first,

My name is Ronnie Kluitenberg and I am 31 years old.
I live in the north of the Netherlands and I work at GKN Fokker Aerostructures as Team Supervisor of the machining department where we make parts for the F35 jet fighter.

At home I have a self-built CNC and I am currently building a serious second CNC machine. This machine has a range in the Y: 400mm in the X: 800mm and in the Z: 400mm. The machine is made of 7075 aluminum parts that are welded and later processed on a Haas VF3.

Now I have Nema34 motors in combination with Leadshine ES-D808 drives on this machine. Now it is the case that I can move the engines in the Pro Tuner software program from Leadshine, but with the Masso I cannot move. I tried another drive (Rtelligent T60) and then I was able to control the engine via the Masso G3.

Can any of you tell me what I overlook or do wrong?

Regards,

Ronnie

Hey Ronnie,



Maybe this link can help

Cheers

Hi Ronnie,

How do you have it connected? Common ground, Differential mode?
I don't know much about the leadshine drive you have. Has it been configured for step and direction mode.
Is there a place in the software where you can view the signals coming from Masso?

Cheers Peter

Hi,

Of course I watched the movie, and I wired my drives in differential mode.
I don't know if I can adjust this in the software (software is called Leadshine Pro Tuner). I put here below an image of the settings that I have now saved on the drive.

Greeting,
Ronnie

Hi Ronnie,

Looking at your settings the first thing I notice is the Pulse input mode is set to 1 which as I read it is CW/CCW mode and not step and direction.
I believe it should be set to 0 for PUL /DIR

There may be more settings but that is the first thing I see.

Cheers Peter

Hi Peter,

Just changed the parameter as you mentioned, but without result.

Why does the driver not do what I want :-(

Greets,

Hi Ronnie,

Does the stepper motor lock up when you power up the drive?
The motor should lock up no matter what Masso does and if it doesn't I would suspect that the drive is not enabled. If the drive does not lock up, ie you can turn the armature by hand when you power it check the Enable Control setting. you might need to change it in Pro tuner.

Can't really tell anything about the wiring from your photos as you are using 3 black wires for the axis signals so no way of telling if they are right by looking.

Cheers Peter

Hi Peter,
The stepper motor blocks as soon as I put voltage on the drive.
It is not possible to turn the motor by hand (without voltage this is possible)

You also ask how I did the wiring, because most cables are black, the diagram below shows how I connected it.

Greets,



Ronnie

I have the same gear as you.

Get in touch with the masso team directly. I had the same problem and they fixed mine. I had to send the controller back and I believe they made a minor hardware change/modification and I just matched all the wiring up as described In the picture you posted and my machine has been Kicking arse ever since.

Hi @hamish and @rk-engineering

Hamish when you bought your Masso it had just been released and included protection resistors in the Step and direction lines. This was done to stop users from damaging the driver IC when they short the outputs or connect them directly to ground by mistake. This unfortunately caused issues with drives like yours and they were removed from your unit. The resistors are no longer included in Masso G3 so the one that Ronnie has is the same as yours. Perhaps you can help by letting Ronnie know what the settings should be for the drives that he has. I have taken my best guess with the information I have but maybe I have put him wrong as far as the Leadshine configuration goes. Since you have the same drives you might be able to give some screen dumps of the Servo settings. Maybe there is one of them that is causing the problem.

Cheers Peter

Hey guys I have never used the tuning software, Never even opened it.

Once I got my controller back I just reconnected and selected my step resolution to be 1600, set the dip switches accordingly and all worked fantastically.



Use the chart on the side of the driver to set the steps via the dip switches and then match in the axis setup. It was that easy. Never looked back.



Obviously check wiring blah blah ensure its all ok, I have been caught out with that sort of thing before at work hence I used the color coded wiring to make it almost impossible to screw up

Hi Peter and Hamish

I see that Hamish also has a G3 version, I don't know how long mine was with the seller before it was sold to me.

@cncnutz Can you possibly see from the serial number if my Masso also has the "wrong" configuration?

@hamish, reading the Leadshine drive is not complicated at all. If you have a communication cable and a computer with a com port connection, it is a piece of cake. It would be fantastic for me to see which settings your drive has, maybe I have an setting wrong ......

I get a bit despondent that I bought a rather expensive system and it doesn't work :-(

Greetings,

Ronnie

I don t have a computer with a serial port so I will have a bit of a fiddle with the connection and a serial to USB converter. I will see what I can pull out of the driver.

I think I will have to dig out an old laptop to see what s going on.


Hold tight I will have a look over the weekend

Don t stress about the masso team I have had a few minor issues and the have been super helpful.

I just spent the last 45 min trying to connect to the driver via a USB/Serial converter and I had no success, If you consider all my settings as "factory default"as i have not ever connected the pro tuner to my drivers this would be a good baseline.



I did not connect the enable connections to mine or the inp + - (I believe these are "In Position") maybe contact the drive suppliers are they Genuine Leadshines?



I tested mine with a simple manual controller from these guys

I am sorry i cant help more i don't have the ability to connect to the driver at this time. I will however call my brother in law he is an IT hero and he may have a computer with a serial port, this may take some time due to our severe COVID-19 restrictions we are having in Melbourne at this time.

Talk soon

Hi Hamish,

Can you please upload the Printable settings file from your G3 please.

Cheers
Peter

 

[hamish]

No worries guys

Anything to help where I can.

Its in pdf if that's ok

 

[cncnutz]

Hi Ronnie

Can you please upload the Printable settings file from your G3 please.

Thanks Hamish. I asked you by mistake, it should have been Ronnie I was asking. Very Embarassing.

Cheers
Peter

Hi Peter,

I am unable to make a printable version (screen) of my settings.
Simply because I can't find the button in the menus ....

I'm starting to get a bit unsure about the Masso, it is the product I expected it to be?

See the pictures below.

 

[breezy]

Ronnie,

I think the printable settings is a new feature on the G3 that became available in version 3.47. You are still running 3.46.1, install 3.47 and try again. If you don't have a copy of 3.47 contact support@masso.com with you serial number and they will email the latest version to you.

In the meantime you can upload the saved configuration files, so Peter can test on his machine.

Regards,

Arie.

Looking at this from an IT engineer's point of view, the parameters set on your tuning software seem to have several non-factory settings. A quick look at the manual shows these defaults:

I would be tempted to save your current settings as a file and keep it safe. Change your dip switches to 111100 (400 PPR, no reverse, no self-test). Read the parameters again to make sure PPR is now reading 400. Press "Reset" to bring everything back to default. Change your dip switches to 101100 (just flick 2 off). Make sure the pulses per revolution has changed to 1600 as this is the factory setting (you may have to re-read the drive). 400 is the software reset default setting as this would be all dip switches set to 1 (including switches 5 and 6 which are reverse and self-test). Someone in the Leadshine factory does a self-test in reverse at 400 PPR then manually changes the dip switches to 101100 so we are just replicating what was done at the factory (minus the test).

Now try plugging it into Masso. You could of course tune them afterwards, but for now just try and get Masso to turn the motor.
