Yes, the DIP switch settings are correct. I was wondering perhaps if the Rorze was somehow detecting a auto shut down condition, but would think the frequency would need to be below 3hz for that to...

Driving with a voltage of ~26v DC. Two OEM steppers, but they have slightly different windings. One has 1.7 ohms per coil the other 2.4 ohms per coil.

All:

Having trouble getting the stepper to draw more than 500ma using the Rorze driver (pdf's attached). I have tried all combinations of coil configurations, half coil, full coil, series,...

Hello All:

Putting together a small project where i need to drive a Cole Palmer L/S 35 peristaltic pump head. According to the specs it needs roughly 60-80 oz-in of starting torque for the...

Hello:

Have a Powermax II stepper motor with steps every 1.8 degrees or 200 steps per revolution.

If I want to use 1/8 microstepping am I correct in assuming this correlates to 1600 steps per...

How did you make the insertion tool, using a dremel ?. Is the insertion tool a necessity or can you use some small jewellery screwdrivers, to work the wire into the connector

Gerry:

Links don't work. Do you have the part number for the cover?

Well, no luck so far. Hasn't responded to private messages on this board or by the way of Ebay.

Do you recall the part number. How is the wire connected to the connector?. Do I need a special tool, or does the wire just snap into the connector?

Yes, I privated messaged him a number of months ago and never got a reply. From his profile his last post was back in 2004, so I don't think he frequents the board anymore.

Hi:

Anybody have a source for connectors for the PowerMax II stepper motors.

Steve:

Where did you get the wire connector (pic 2 and 3)for the Powermax II

Oops, guess the link is dead. here is the pic of the stepper. Reason I needed to pin down the current and voltage for the stepper is I am using a Rorze RD-021M driver and need to calculate the...

Thanks for the help, it's all starting to make sense now.

Here is a pic of the stepper and I plan on using it as is to dispense small amounts of liquid.

I looked at the label again and it has the following specs
P21NSXS-LSS-NS-04
1.16A Bipolar Series
Po 30W
Vs(dc)65

The exact model does not appear in their catalog and I sus[pect it is a OEM...

Gerry: If the current is 1.414 times the single coil current and i am running in parrallel the resistance of the parallel coil becomes approx 1.3 ohms. Does this mean the rated voltage would be

Hi All:

Have a PowerMAx II stepper with the notation on the label 1.2amps. I have checked the resistance of each coil (4 coils) and they are approx 2.75 ohms each.

So can I assume the...

Does this help

You mean like this simple schematic.

All:

Would really appreciate some help on my little project. I have acquired a dual shaft stepper motor connected at both ends to pump heads. This item is surplus and is designed to dispense...
