"It seems your amplifier is in torque/acceleration mode as the Position...." Yes, it is. I'm guessing that encoder-velocity would be better? I'll have to figure out how to run the signals from the encoders to the driver, since they're going to the KANALOG right now - and they're differential. Can I ...

Here are screenshots of my setup:
Configuration IIR Filters Step Response Setup The deadband is due to stiction in the bearing carriages.

There are commands to directly command the DAC Outputs. See here. That lets me set the maximum output, not the actual DAC output. Yes I can use a power supply, but it's nice to be able to confirm that the entire chain works electrically. I did have a grounding issue that I had to work through with ...

Ok, thanks. Yes, they're differential encoders, and the position signal comes through properly - it's only the Z signal that seems to be missing, or at least I can't see it.

You're right, it was. I had to flip the "invert" switch on the driver. Might I suggest adding an "invert output" switch capability? Now I can't get this thing to stop oscillating. I have the following settings: 100 Hz low-pass filter 2nd order filter on filter 2 P = .1 I = 1e-5 D = 0 Gain = 1 on the...

I'm using two Renislaw LM10 magnetic encoders https://www.rls.si/eng/lm10-linear-magnetic-encoder-system , with RS422 differential outputs for feedback on my servo system, attaching to a KFLOP/KANALOG. As per the manual, the A and B outputs attach to JP1, channels 1 and 2 for the first stage and 3 a...

I'm not up to speed on servo systems and could use some help in getting the loop set up. The system is as follows: an H2W Tech BLDM-B02 https://www.h2wtech.com/product/brushless-linear/BLDM-B02 linear motor driven by an AMC AB30A200AC servo amp https://www.a-m-c.com/products/?page=product&id=AB30A20...

*For checkout and initial setup, it would be quite handy to be able to directly command the output, especially the DACS, to a given level and bypass the control loop. I had to play with things for several days to insure that the output polarity was correct with respect to the position encoder. (Turn...

I'm trying to figure out how to have a PC send commands to the KFLOP program (mostly "GO"). Correct me if I'm wrong, but the program running on the KFLOP can access the RS-232 serial port (via the KANALOG, as per http://www.dynomotion.com/Help/RS232/RS232.htm) but can't access the USB connection exc...

Thank you. There are Hall sensors and they go right to the driver amp.
