Recently my CF531 has exhibited a delay in stopping.? When I press the stop button, the machine begins to slow down but then increases in speed and I have to wait 5 to 10 seconds before the machine stops completely.? This is the case for all of the combination machine functions.? Does anyone know why this is happening and how I might correct the problem.??
Thanks, Laurie Lewis

Can you confirm that it increases in speed or just does not continue to slow down. Thought being, that the brake is kicking out after a short time. ?If it is indeed increasing in speed then I need to look at the schematic.? If you have one you can share high resolution pics. Make sure you are able to read lettering etc when you zoom in.
One thing you can try is to keep the red button pressed continuously to see if it makes any difference.

When the stop button is pressed, the speed slows slightly but then returns to the normal operating speed for 5 to 10 seconds and then the motor reduces speed and stops.? If I press and hold the red button continuously, it makes no difference.? It actually seems to extend the time before the machine stops.? I have the original user manual and there is some type of schematic in the back of the manual but all of the writing is in german.?

Laurie,
Thanks for confirming. This is an interesting anomaly. German is fine but need schematic to offer any assistance.?

This is the schematic in the user manual.

Laurie - As other posts here have mentioned, Google translate or a decent German-English dictionary is a good part of the Felder/Hammer tool kit.
Good luck with this, Imran is pretty savvy about the electrical troubleshooting.
On my C3 combi machine, the braking circuit has a distinctive 'buzz' when it is braking the system.
I need to shut off the dust collector and remove ear protection to hear it, but the buzz may tell you if the brake is working. ???? -Rich M.

Hi Laurie,
Not sure if you are interested in trouble shooting. It is hard to guide people remotely and many times requires 2 people. So I suggest you replace K1. From schematic it appears that your machine is from around 2007.

Sounds like the brake board might need some adjustment. I will look for some documentation and get back to you. There are two pots to adjust, and it only takes the slightest tweek to make a difference.

Bryce

Ok, so here is a pic of the brake board. It should allow some adjustment, see picture, should be P1-Time to stop ?P2-Torque to stop faster. It is a fine balance, the board can wear out over time making full adjustment range not possible. Fine adjustments suggested!!
Hope this helps.

Bryce

Bryce,
For this reason, I asked Laurie about speeding up or brake disengaging. He confirmed that it actually speeds up. So my first shot in the dark is that K1 contacts are sticking.

Yes, I'm in agreement with Imran, if you push an E-stop it will latch open.
?
If the machine continues to run it sounds like contactor K1 is sticking.
