Yeah... I think we're both looking for the same thing and missing the same pointA latching switch isn’t going to work is it, if I hit the stop it’s going to re-start when I release it (I think?)
Mine too. I've just taken the rather radical step of emailing the supplier - my expectations are extremely low, but you never know!Nothing pertaining to that in my instructions, but my Chinglish isn’t too great.
Do you have a normally closed link that you would just remove (normally closed switch)?
Yeah - mixed info (as ever!) on the two models. The image for the YL600 (the one I have) does not show a resistor, but the image for the YL620 does.
But then the one I have does have the connector for the resistor
I'm probably imagining a problem that doesn't exist - I'll worry about it if the VFD starts showing over current/voltage on stopping.
My interpretation would be 'stop' brings the motor to a stop as per how the VFD is programmed, whereas 'emergency stop' will stop it far quicker (either via DC current injection, or ramping it down quicker, which may trigger an overvoltage freewheel if there's not braking resistor fitted).More progress thanks to encouragement from @skotl - it now starts on the momentary button so no relay required. It was P50 = 3, keying operation, with a wire to X1. I can’t get it to stop at the moment though...
Is there any difference with a VFD between ‘stop’ and ‘emergency stop’? Would it be bad to use an ‘emergency stop’ function for general purpose stoppage?
Braking resistor is only needed if you're trying to stop the motor too fast, which would trigger an overvoltage fault when trying to stop. On most VFDs all that means is the motor would simply coast to an uncontrolled stop if the fault is triggered, then probably need a VFD reboot to clear the fault (some VFDs may self reset, some may have a reset option, but most need a hard reboot).
My interpretation would be 'stop' brings the motor to a stop as per how the VFD is programmed, whereas 'emergency stop' will stop it far quicker (either via DC current injection, or ramping it down quicker, which may trigger an overvoltage freewheel if there's not braking resistor fitted).
Congrats - quite nice when it all comes together, huh?It seems that walking away for 24hrs and coming back to it does the trick with this (or me). Got it first attempt tonight...
Don’t know why it didn’t click but the post from @skotl gave me a clue. P50=X1, P51=X2 and so on... why couldn’t they just write that down?
Now I just need a momentary stop as my latching one is pointless.
