Hi
thanks, yes other builds are using them, it allows the VFD to dump current into the resistor which allows it to stop the motor quicker without overheating or damage.
there are guides in the wj200 manual on which resistor to choose are ask your supplier when you get your vfd's.

HI All, Still busy working through the wiring for my sim and have a couple of questions if any one can help.. Firstly with regards to the 1,3,5 .. 2,4,6 direction, I understand its necessary to reverse the wires but do I do this at both ends (VFD and AMC) or just at the AMC end, leaving 1&2 ports on WJ200 the same. Also I'm having difficulty finding the correct male crimps/terminals to fit the pcb screw terminals on the AMC. Ive just ordered smaller boot lace terminals (violet 0.25) as the blue ones I have for the WJ200 wont fit the pcb terminals on the AMC but still have the feeling they might be to big. If anyone can recommend the best wire terminals for hooking in to the amc that would be great. Really not happy with running bare wires into the terminals as past experience has lead to reliability issues this way especially with the smaller guage wire like the speaker cable I'm using for the pots. Fault finding a random issue that after many hours turns out to be a dodgy connection is a frustration I would like to avoid  Thanks for any advice... |

You can hook up bare wires, if you strip 1/2 cm from their end and tin them.
Thanks

Hi Thanos
Yep i tinned them, the .75mm CY cable i have used for the 10v control cable is passable, the speaker cable for the pots is not great even when tinned.
may not have much choice if the .25 bootlace terminals still dont fit. i will keep searching for a more robust option.
am finishing the pot mounting brackets in the mean time and am just waiting for ian to get back to me re bff software.
thanks.

OK time to ask for some help!! Been fiddling with the wiring on and off for the past 2 weeks and seem to be running out of ideas, At the moment i cant get movement through the AMC. Motors all work fine when run from the Wj200 panel (F001) but after switching to terminal control (a001 and a002) i cant get movement though the amc with the directional buttons on the board. I have a pot connected to motor 1 and have 5v at the pot on multi meter. Have made all settings as per the guides i can find but no movement so far so im obviously missing something Some pics of the settings so far, if anyone can notice any obviously problems then please let me know thanks!:    Havnt changed any dip switches etc on the board since delivery so im assuming they are correct. Main board dip switch 1 is on, 2-4 are off. Im assuming that testing motor movement with the on board directional buttons is the best way to test as this eliminates most of the software/config variables. |

hi Thanos
Yep the inverter jumper is on L/PLC ie source. the inverter settings are also as per dropbox files.
if i take the inverter off terminal function (a001/a002) then i can move the motors manually directly from the VFD so power/control direct to motor is OK.
I know i have power going to pots as have tested that.
A q' re baud speed in com port settings, it sais to set to 250000bps but i only have option for 230000 something not 2500000 so at the moment i just set it at maxmimum as per image above. (921600)
maybe this is an issue? but this still shold not matter if i control motors directly from AMC using direction buttons.
Do the settings for the AMC from fabi's softare shown in image above all look correct?
ive checked the jumpers on amc and 6dof board and they seem to be correct also.
thanks for any help..

Hmm, something must be wrong with your wiring, all the rest look good on the amc1280usb side. You don't need to set comport speed, it sets automatically from the software.
Can you take some photos of the wiring on the 6DOF ext board and the inverter.
Did you measure the 24v power supply to the 6DOF ext board with multimeter?
Also could be a setting in the inverter that prevents the motion, perhaps you need to add a switch for "enable" input on the inverter.
Thanks

OK Thanks,
Pics of wiring to vfd and 6dof board attached above. I can label them up to make easier to see whats going where if not clear.
6dof board has power or at least green light is on, ill check that its getting 24v with multimeter tonight.
I also tried to measure voltage out from 10v outputs with multimeter by putting - to ground and + to inputs and then out puts whilst pressing the directions buttons on amc but could not get any voltage reading.
Ill also keep looking through inveter settings to see if there is another setting ive missed.
thanks.

Measure the 10v outputs with the wiring to the VFD inverters disconnected. If there is a wrong setting on the inverters and the signal is sinking (current reading) you won't be able to measure it. See here: youtu.be/aUoZ_3tSuNkThanks Thanos |

Hi Thanos Thanks for the advice... firstly i found out something, just because the light is green on the 6dof board, dosent mean it is getting 24v! stupidly id switched the fuse off for the 24v PSU at some point and forgot so school boy error aside, ive disabled all inverters at the moment apart from vfd/motor 1 to help trouble shoot. i checked the 10v outputs with multimeter. Without the VFD connected im getting 24+ volts from 24v A/B 1. with the vfd connected this drops to 1.8v on A+B. on the 10v outputs im getting 3.3v with and without the VFD connected. does this sound correct? still no movement using direction buttons on AMC.. |

3.3v max sounds correct as the max Offline speed is set to 25%.
Now about the voltage drop on the 24v signals, I'm not sure. Are you sure it's set correctly to Source mode?
You can verify by connecting a pot on the analog speed input on the VFD, and supply 24v from the external PSU to the direction input of the VFD. If all settings are OK, it should move.
Thanks
Thanos

I have the short bar connected to L and PLC which as i understand it puts the vfd into source mode for analog inputs 1-7. i dont think there are any settings other than that. (as per images below) the 2nd image below indicates that under 3v put analog input to off so if amc 24v is only sending 1.3v when pressing direction button this would explain why no movement perhaps. programes C001 and C002 which sets the inputs 1 and 2 are set to forward and reverse so pretty sure thats correct. re connecting pot to analog input ill give that a try tonight and see how i get on and let you know, thanks!   |
