Anyone Familiar with Slo Syn MD4 drivers

[gone4pepsi]

Anyone familiar with any of the slo syn drivers. I'm considering purchasing the ss2000md4 for my minitech upgrade..

My question was as to who's breakout board would i use (who's will work) can someone help me out configuring the pins to the board they are labled opto , awo, dir, pulse.

What are are the recomendations for setting my amperage. Should I set it lower than my steppers are rated?

Are these drivers suited for my application?
Thanks

Gone4Pepsi,

I use a CandCNC mini-IO breakout board. My SS2000MD4 has 4 I/O input pins. I set the current at the max for the stepper.

See attached ss2000md4-IOin.jpg.

They are pin 1 (Opto), pin 2 (Pulse), pin 3 (Dir), and pin 4 (AWO).
AWO must be high for enable the motor windings.
Opto must be high to enable the opto-isolators.
Pulse is the step signal.
Dir is the direction signal.

Ground on the SS2000MD4 is common for the driver voltage supply and the 5v logic supply.

PC IO DB-25 pins SS2000MD4 pin
+5V (not really available on DB25) Pin 1 (Opto) (+5v from mini-IO)
Pin 2 (X step) Pin 2 (Pulse)
Pin 3 (X dir) Pin 3 (Dir)
Pin 17 (Enable or Mach 3 charge pump) Pin 4 (AWO) (or +5v from mini-IO)
Pins 18-25 PC gnd

I appreciate all your help, but still have questions, maybe it's just the terminology that i don't quite know yet.

I'm still in question with the " aWO" and the "opto" Is there a dip switch that i will set these to high with and were to i connect these two terminals? Where does the mini Io come in from the breakout board? Just not gettign the termimology. I'm sure you'll tell me what i need to know
Thanks

gone4pepsi,

Mini-IO is the name of the breakout board sold by CandCNC
http://www.candcnc.com/

AWO stands for "all windings off". It has to be pulled high (+5) to enable the motor windings.

Opto is power to the opto isolation circuitry. It has to be pulled high (+5) to enable the optically isolated input circuitry for step and dir.

There is no switch setting for them.

J2 pin 1 is OPTO.
J2 pin 2 is Pulse (step).
J2 pin 3 is Dir.
J2 pin 4 is AWO.

J1 pin 1 is phase A+
J1 pin 2 is phase A-
J1 pin 3 is phase B+
J1 pin 4 is phase B-
J1 pin 5 is Motor power max 40vdc.
J1 pin 6 is Ground

Which breakout board did you use on yours? Are you real happy with these drives?

[acondit]

The name of the breakout board I am using is "mini-IO". It has been updated and is now sold as the "mini-IO-2".

I am using SS2000MD4s in my CNC router and I get speeds up to 120ipm. I am building another controller with them to CNC a lathe. I am also going to use some on an X2 that I am converting to CNC. I think they are fine for small machines. If I were doing a larger or heavier machine I would probably think about Geckos. They are limited to a max of 3.5 amps and 40 volts so it depends on what your particular needs are whether they are a good choice or not.

Below is a picture of the lathe controller that I am building.

I like your setup. By the way,what's a good price to pay for these drivers? Do you have asource for them?

[acondit]

gone4pepsi,

I bought mine on ebay. I paid about $30-$40 apiece for them. Although I have seen them sell for as much as $80 apiece. I don't know of any good source for them though. I bought mine from SunnKing (sic). They were selling them in lots of 3 to 8 at a time.

Help please!

I have a Slo Syn ss2000MD4 controller driver.
How I connect it to my pc by usb or serial port?
Thank you!

It does not connect to either the USB or the serial port.

It connects to the parallel printer port which is a DB-25F (FEMALE) connector. A Female connector is the one with the holes.

A printer cable is plugged into the parallel printer port. The other end of the cable plugs into what is known as a Breakout board.

The breakout board has screw terminals which are the output signals to the MD-4 drive with the exception of the 5 volt logic supply. I am not familiar with the breakout board mentioned in the above post, so I do not know if it is an active or passive breakout board. (Active means the breakout board requires 5 Volts -- Passive means it doesn't require a 5 volt supply) Post number 3 has all the information that is required to wire up the system.

I use the SS2000MD7 drives (7 Amps) and love them.

CJL5585,

The CandCNC mini-IO board has an onboard transformer and 5vdc supply.

Does the SS2000MD7 connect the same as the MD4 ? I have a mock up for my pcb mill just sitting on the table lonely as hell.

I already figured out that the green and black are paired and that blue and red are paired and those are already placed in connectors just really still concerned about the lpt pinouts.
