DON'T MOVE THE "ENCODER". If you do, it could cost you more than it's worth to have it realigned, for proper commutation.

As far as no firmware from the factory, that is not typical. Most of the CLX come with something like v2 installed. Also, even if your programming software doesn't support that particular processor,...

Is there a serial port on that particular processor? I had a similar issue once, and was able to connect via 9 pin serial (yes, my laptop still has serial) to update firmware. It takes a couple...

Yes, he can run it from an inverter, but I thought he was looking to run it straight off the line.

What is your application?

On that drive, it is apparently not possible to run on single phase. The error is telling you there is a missing phase. The derating only applies if your drive will accept 1ph. If it WOULD accept...

From what I see, you SHOULD be able to run it single phase. You MIGHT have to derate the drive. Looks like a 750w drive, 200v 1/3 ph. Do you have a drive you can hook up on a bench? This is to make...

I'll have to look more deeply tomorrow. The only links I can find on this model looks like a scam site...yaskaaw? Nope... not gonna bite! Lol

What is the specific model number you are looking at? SOME of the servos they make can be ran with 1ph power.

When it's supposed to be in motion, it's there any vibration or noise from the malfunctioning stepper, or is it just holding?

^^^^^This... moving the machine shouldn't have affected the tuning... unless something mechanically changed. Did the drive retain the parameters you had in it? If so, check all your wiring,...

Yes... and it was my plan to try that next. Just have having to remove covers, remove pulleys, belts, etc. But again, that's my next move. Thanks!

No, I haven't. Do you mean on my 70V bus supply, or on the main lines coming into the machine. Why would this only affect 1 motor out of 4?
Yes, to no avail.

Sorry to revive a dead thread, but I'm having issues with a ClearPath SDSK implementation. 3 axis router, with the 4th axis slaved to the 1st (for the x axis gantry). The slave motor keeps faulting...
