we’ve chosen this combination for our new project. Initial test bench consisting of a LAC board and a L16 linear actuator worked fine. I could move the actuator using a potentiometer and software also. So I switched off the setup and went home. Next day after power up nothing worked! I did not change anything, just power down and power up. I use a laboratory power supply for my setup. The weirdest thing ever is, it happened to all boards (3) and all motors (L12 and L16). So nothing is working now. I did not change any parameters, the communication with LAC is working (I can see the actuators position on the bar graph display). The parameters in the advanced configuration section are on default.
When I try to change a value in the configuration utility dialogue an (error?) sound is audible but nothing else. Do anybody noticed this kind of behaviour? Any hints how to repair it, and, last but not least, what I did wrong???
Please provide a few pictures of your setup, showing clearly the board, all connections and other components wires to it (power, potentiometer, etc.). You can attach your pictures to your reply using the Full editor mode. You need to open the Attachments bar above the 4 orange buttons (Preview, Submit, Save draft, Cancel). See the attached image for details.
We have contacted the manufacturer concerning your issue and we will post again once we have more details.
Hi,
I do not have a camera handy so I can not send any pictures today. But: my configuration did work another day, next day everything was off. I did not change anything! Same setup, same position of potentiometers. Today I tried again, and I got the setup up and running for certain time. Than it was dead again. It looks like the PIC-controller is locked from time to time. When I attach the USB-cable there is a short communication (the actual position of the actuator is read) but it breaks soon and the motor shows no reaction and the bar goes from green to gray (still showing the correct position).
What I tried today is moving the potentiometer fort and back (bringing back to old settings), than doing a power cycle and the system was on again. I moved to Linux now and I’ll test if the hang-ons disappear.
Maybe the potentiometer in the PCB are somehow broken?
Here is a copy of the response from the manufacturer after reviewing your posts:
The manufacturer also mentioned being in contact with you a little over a week ago. Did you have any changes in your setup since then?
As mentioned by the manufacturer in their response, pictures of your setup are definitely required if you wish for us to try and identify the problem(s).
Sincerely,
P.-S.: Please find attached the picture from the manufacturer.
Thanks for the hints. I’ll check our power supply, but it shall be good enough for the setup. Since the LAC and motor are now working good with Linux, I’ll test it more intensively next days. For now I’ll stop the topic.
BDW: Device Status was “Connected” all the time.
