WJ200 E06.3 fault

[mksj]

I would do a parameter reset to stock, and then do just a few parameter changes at a time and check everything. Set A001, A002 to the control source and A003 to your motor base frequency. I would set A044 to 03: (Sensorless vector (SLV)), put in the motor parameters H003 and H004. Then run the motor Auto-tune H001, and after that is completed change H002 to 02 (Auto tuned data). Just start with the simplest changes, if you still have a problem then something is probably defective. Just to confirm the VFD is single phase input model and is sized accordingly for the motor FLA? Also check your line voltage, it should be at least 10V above the motor specified voltage.

I did a factory reset and followed your parameter instructions. I did an auto tune with no motor rotation then set parameter to use auto tune data. The machine shut down after 2 minutes when running at 2,000 rpm. The vfd is a wj200 2.2 kw. I checked line voltage coming into the vfd and it said 249v.

So I assume this is the same fault code? Do you have a picture of the motor plate and I am assuming you are using the WJ200-022SF and not LF, how old is the VFD? Do you have another 3 phase motor you can try the VFD on?

Try setting
B095 = 0 which should disable the dynamic braking control (BRD)
B096 = 380V which sets the activation level to a higher voltage

If those parameters do not mitigate the problem, then you may have a faulty braking SCR chopper, sounds like it is on while in the running mode. What I gather from other information is that if the line voltage is very high that this can lead to a higher buss voltage which could trigger the braking resistor circuit. I calculate your buss voltage to be around 352V which shouldn't trigger the BRD.

Same fault code Mark. This is an SF unit. If I was to guess, this unit is 4-5 years old. I don't have another motor laying around to hook up at the moment. I will change the parameters you suggested and see what happens. Thanks for help!

Just changed those parameters. The resistor didn't get hot while it was running. I shut it off and got error code E02.2

I changed F003 deceleration time to 8 seconds and enabled B095. As of now I am not getting any codes and my resistor is not getting warm.

Can't go lower than 8 seconds. This truly is not a problem to me as I have never had braking before. It's just odd that for one day it was working fine at 2 second deceleration time.
