Servo Motor Error ??

[Appaloosa]

HI!

I have a New Tech Servo  motor on a Consew 206 RB1  that has been working fine until I moved my table to another location in the back of a pick up. Had it strapped down and covered but did take some AZ desert ranch roads which are a bit bumpy. When I  reassembled and  plugged machine/motor back in.... the panel on the servo  just flashes "Pd". Panel is lit up and  gets power but motor does not activate when pedal is depressed.  Checked the wires and wattage all good. There is no manual and nothing online. Wondering if anyone knows what" Pd" means on a servo motor and how to fix it or clear it. Thanks in advance

maybe this manual will help. According to this manual PD seems to be a "pedal warning"

Thank You!!  Not sure what the pedal warning  means... as the pedal rod is connected and the shaft on the motor and depresses when the pedal is pressed. Will fiddle with the pedal alignment and see if that helps. Appreciate the manual 😊

My guess:

The black internal lever with the magnet on it (on the inside of the accelerator unit) which is attached to the external lever where the pit man rod is attached to (other side is attached to the foot pedal) has shifted and the magnet no longer is aligned with the hall sensor. That probably happened due to the bumpy roads you drove.

Just my guess.

Assuming it looks similar on your motor - see pictures:

happens when you are not logged in, should be available when you are logged in.

Thanks so much. I so appreciate your input.  Would the depression of the plastic white piece be creating that problem?? I have two of these motors and on the one that is working the white pin does not move and the one that the motor is not activating does  move/depress with pressure. 

[Appaloosa]

 OK.. now Wondering where the magnet is suppose to be set....🤔

Plastic white pin is for back-pedal.

for normal sewing you press the pedal down and the motor starts, the more you press the faster it spins

for back pedal you press with the heel, pedal moves up. In my case it is used to put the needle in the up position (used togetehr with needle positioner).

While starting / sewing the plastic pin should rest in the lower position. Only when you back-pedal the plastic pin is pushed up. I guess here could be your problem. Adjust your pedal and the rod.

But the machine has no needle positioner as it seem (see hand wheel) so in this case the white plastic nub has no purpose.

[nejcek74]

Yes, it looks like there is no positioner. One of my similar low cost servos didn't operate without positioner, even when the function was switched off in the menu :))) I checked his video again and actually it looks that the white pin operates as intended. Or so I guess.

[Appaloosa]

The servo motor worked fine with no positioner system prior to transporting to a new location....so thinking it might have to do with some internal  misalignment as Constabulary stated.

Can we see a photo of the connector that plugs into the controller?
You can slide the rubber shield back so we can see the individual wires. Want to make sure none of the wires broke.

I think the comments above have it. Even if the motor is not using a needle positioner encoder, if the linkage for the pedal is misadjusted the motor is likely getting a signal immediately at start-up that it can't use or doesn't know what to do with. This would make sense if it started doing this after transporting the machine, as it's common for linkages and legs to shift such that the Idle pedals position is different than what it was previously.

@Appaloosa, have you taken that control box apart and looked in it?

I'm on team Constabulary, I think something rattled loose inside it.
