Home Forums General Discussion Technical Questions GAL MOVFE CAN BUS

Hello,

To enable Can bus on the door operator it says to change parameter 11. Parameter 11 does not exist even when it says to place door op in setup mode to be able to change parameter 11. Signal feedback is being recieved in the machine room from the door operator, however the door operator does not appear to be accepting CAN open close and nudge signals. Parameter 11 probably allows that. No idea why I cannot get into parameter 11. Any help would be great. Thanks.

What kind of controller are you putting it on?

Not all that familiar with the MOVFE but looking through the manual there are bit settings to view the status of the operator switches. However unlikely...maybe the setup toggle is no good? You should probably see the bit turn on and off and it looks like that needs to be on to access parameter 11.

Thanks. I pretty much ruled out the setup switch not working as I had to put it on setup to allow default centre opening parameters to be written to the drive. However maybe there is more than one pole or input. You never know.

You have to set parameter 15 from zero to 6301. Then parameter 11 is visible. 🙄. Hidden secrets.

Are you talking about parameters on the door operator? I just recently installed 4 of these with any issues. Are your red communication lights flashing on canbus card on door operator? Is your jumper on board setup properly for front or rear door?

All working. Needed password 6301 to get in and change. No jumpers for these movfe. Just params. Maybe the movfr has a jumper. I'll find out when I do one of those soon.

Does anybody know how to go back to discrete. I have an movfr2 with can bus, and after changing the operator, CanBus card and wiring it directly back to the controller, it still craps out after 5 minutes. And now everybody is pointing fingers because the can bus cards shield terminal is grounded, and it shows the shield grounded on the cartop board side with the shielded landed on the terminal in the movfr can bus board. So is it grounded on both sides because of the VFD? No response on that.
So, back to discrete we go. But how? Nothing in the cons file related to operator can. Infact, door and can don't even show up on more than 2 lines......

I don’t know GAL controllers but anything you want to keep noise out of like encoder or comm wiring you do not ground on both ends for any reason. It makes the cable like an antenna and noise will be worse than no shield at all. It is common practice to ground both ends of a power cable to keep the noise contained and prevent it from getting to sensitive signal wiring.
