Same thing I asked. No response. It’s the first that should be checked.

Does the motor direction correspond to the encoder direction?

Those are the resolver signals.349972

Just make sure that the drive is compatible with your current controller. Yes, good prices can be had on Chinese products, but buyer beware. Read the fine print about the shipping time and costs. ...

Sorry, I'm not really familiar with those drives, I just looked up the series online and had a look at the user manual. At least with the position series, it looks like you can input step and...

Looks like you have the speed/torque model and not the position model. That means you need a controller that outputs +/- 10 volts. Check out the Logosol LS-180. It can be controlled with step and...

I think that in order to "configure x4" in the Kollmorgen software you have to follow the instructions in the manual for turning on the step & direction mode. I'm not familiar with the software so I...

Just had a look at the servostar 400 manual. Pages 67 and 68 appear to cover what you are asking. The drive can be set up in "following" mode, whereby it can accept step and direction input, so it...

Unless your drives accept step and direction. The kollmorgen drives i have don't.

More information is needed. What is the make and model of your drives? Do you have a pdf manual you can share? If your motors have resolvers then your drives are going to need to have encoder output...

I think the deadband would only be an issue if the encoder feedback came from the axis rather than the motor.
Your problem really sounds like a tuning issue. Does your drive/motor software have an...

I would try an unregulated power supply if you have one. I know that some people use switching (regulated) power supplies without problems, but I don't know if they oversize them. Plus, it's so...

Although that might be only for parallel port control.

Just a heads up -- Artsoft says that Mach3 does not work with 64 bit Windows 7.

I run Linux CNC and like it. It is easy to install and set up. I used to run mach3 but got too frustrated with the requirement to run an older version of windows. I installed an old version of XP...

Lots of options. As others have said, it looks like your drives accept +/- 10 volts, which is pretty standard. You could keep your drives, but you are going to need a PC with either an internal...

Post pictures of your motors and the back of your pc, plus model number of motors.

Does the pc have a parallel port? If so, and if the baldor motors are brushed dc, then the simplist (and cheapest ) approach is to go with some gecko G320X drives and Linux CNC.

Gecko makes a brushed dc servo drive that accepts step and direction.

Is the charge pump disabled? Is your power supply regulated or unregulated?

Gecko has a pdf on how to tune the G320X without an oscilloscope.

Tim,

Do you have anything to share now that you've had this for a few months?

Hi Gary,
Whenever I set up a new stepper system, I like to hook it up to an Arduino Uno running Grbl. It's fairly fool-proof and you can count on a good 5 V pulse. Once you know your steppers and...

I still think you should get the largest motor your budget and power supply can handle. Without a full engineering analysis, it's just an educated guess anyways. If you go with a small motor and...

Recommended stepper motor voltage is 32 * sqrt(inductance in mH), so you want a motor with an inductance that will give a voltage close to your power supply. You said you have a 48 VDC power supply,...

Did you check the actual voltage coming out of the power supply? They are typically rated at an input of 115 or 120 VAC. My house reads 125 VAC on all of the outlets, so my DC (unregulated) power...

You need to perform some torque calculations, taking into effect any gear reduction you have. A quick and dirty method would be to turn your linear drives manually and estimate the amount of force...

I agree with awerby. Probably wiring. Try disconnecting your motors from the machine and running them free on the bench. If they start to move and then stall then you are probably trying to spin...
