DMM DYN2 wiring drivers

[paulmac21]

I'm building a 5' x 10' plasma table and am up to wiring the motors on the table and hopefully getting some motion. I've looked at the wiring diagram for the DYN4 drivers and have a couple of questions. Step and dir signals are straight forward enough, wire from driver to control and alarm to any input, but the it says wire COM on DYN2 driver to +VE on Masso?

I'm not great with wiring up things but is COM on DYN2 to +VE on Masso correct? Doesn't seem right to me, but then I'm still learning! For the moment I've only wire the 4 signal wires and can get it to move but only in one direction for both left and right. ie only goes right.

Also it would be nice if the DYN2 driver wiring diagram could be added to the documentation and perhaps add the wiring for the ENABLE on the DMM drivers too.

Paul?

I think the connection of DYN COM to MASSO +ve is a typo, have looked at the manual for both DYN 2 & 4 and to me the COM terminal should be connected to the -ve or MASSO's "ground" connection point.

In regard to the enable terminal on the DYNs, my take on this, is if you connect the ENA to +ve 5 volts, you will disable the drive, but if left floating the drive is enabled.

For the moment I've only wire the 4 signal wires and can get it to move but only in one direction for both left and right. ie only goes right.

If you have a G3 MASSO ensure that you have entered settings (can be dummy) in ALL axis, even if they are unused. Leaving any axis without settings can cause all sorts of problems.

Also it would be nice if the DYN2 driver wiring diagram could be added to the documentation and perhaps add the wiring for the ENABLE on the DMM drivers too.

On the bottom of the Contact page is a request form, complete that requesting addition to the documentation, supplying all the links to the documentation on DYN2 driver, also provide a separate request to correct the error for the DYN4 driver.

Regards,

Arie.

Thanks for that. I didn't think connecting COM to +VE sounded right. As for movement only in one direction , I had put numbers in boxes but for the max and min for the axis (while testing) I had them both as a positive number, meant to put one as negative till I'll got the axis calibrated. Didn't help I was trying to do it a 1am and with a pair of 'backup' glasses!

Anyway got things moving, but thanks for the reply.Lots more to work out yet.

The only requirement for the max/min is that min is less than max, both can be positive.

Also Interested in the DMM Dyn2 to MASSO wiring diagram. Please note there does seem to be two versions of the Dyn2 drives by Dmm-Tech with very different looking Pin allocations for JP3. I will upload the older Dmm-Tech Dyn2 Manual here. The first page includes all Pin# allocations. Hopefully someone can tell me the exact Pins to connect for my drives.
Finally, sorry to hijack your thread pualmac21, but it seems spot on target "DMM DYN2 Wiring drivers", and I wanted to help keep it clean for anyone else in the future seeking this same info. Please let me/us know if your Dyn2 documentation is different to what I posted.

Regards Matt

Matt,

What version MASSO do you have G2 or G3?

From your manual connect your drives as per the drawings in Gecko 203V .

If G3 all drives per the first drawing, otherwise follow both drawings.

Regards,

Arie.

Hi Matt, have added pinouts page from current manual for my DYN2 drivers bought 2019, a bit different from yours, plus more pins. I used the one in the Masso Documentation, connecting Dir+, Dir-, Pul+, Pul- to the Masso, just didn't connect the Alarm or COM yet. Works fine like that with the current DYN2 Drivers.

Hi All,

@breezy, For your question I am using the MASSO - G2.

@paulmac21, Thanks, hope it helps someone else, unfortunately as per the document of the older drive I put up, my older Dyn2 with the less pins doesn't mean less confusion.

Seems the newer version is quite straight forward with its extra pins - dedicating some to the differential Pulse+/- and Dir+/- signals, however the older one seems to double up on pins from the documentation I see. As below is the pin naming for the older drives.

JP3: position command port

Pin 1: Gnd

Pin 2: Motor free signal (low active) Pulse/Dir, CW/CCW mode, Analog Input 0~5(Vdc) for analog input mode.

Pin 3: CCW, Dir, serial data in(SI) for SPI mode(Optional).

Pin 4: CW, Pulse, serial clock input for SPI mode(Optional).

Pin 5: On position signal (low active) for CW/CCW mode, serial data output for SPI mode(Optional).



If it makes any sense to any of you, i am not well versed in this terminology, but hope not to blow my new MASSO controller or old parts.

Kind Regards, Matthew

Matt, yep so far the newer DYN2's have been quite easy to setup.

Breezy said look at the wiring for the Gecko 203V, the first one. I would be pretty sure that you connect as follows;

Masso Dir+ -----> DYN2 Pin 3: CCW, Dir,
Masso Pul+ ----> DYN2 Pin 4: CW, Pulse,
Masso COM ----> DYN2 Pin 1: Gnd

If someone else can verify this it would help Matt feel happy to try it.

Matt,

however the older one seems to double up on pins from the documentation I see. As below is the pin naming for the older drives.

Yes, the older drives had limited input/output pins on their microprocessors, so the input pins had do multiple duty and how they reacted to the input signals was dependent on the parameter settings. This made it hard to determine what pin did what and what parameters to set.

As I said earlier and Paul has confirmed, connect as per the Gecko 203V drawings.

Also double check that you have the Step & Dir parameters set, otherwise it won't work or do funny things.

The wording in the manual is incorrect because it doesn't match the drawing.

3.6.3 Pulse/Dir input mode
For Pulse/Dir input mode, the Pin2 and Pin4 of JP3 are used for sending direction and pulse to Drive.
Also if |Pset - Pmotor|<=OnRange, Pin 5 = low, on position, otherwise Pin 5 = high, off position.
If Pin2 = low, motor will free, otherwise will be servo active even open.​

Pin2 should read Pin3.​

Pin 2 is for enable/disable - leave NOT CONNECTED, this should enable drive.

Pin 5 is output that is not used by MASSO.

Arie.
