Are you sure you have a genuine Huanyang VFD Drive
Huanyang VFD, Mach4, mb2ess issues
Hi Guys,
got an issue with the correct wiring for the mb2 to my new huanyang 3kw vfd. I have been at it for 2 days now! can anyone please explain the connections between the anaspeed circuit on the MB2, and the terminals on the VFD? I get no response from the vfd even though I've been over the wiring and programming so many times my head hurts!
Tried rs485 and modbus but i get no joy with that either!

Re: Huanyang VFD, Mach4, mb2ess issues
Yes i conneted 10~+ to the ah terminal, AL to the acm
Re: Huanyang VFD, Mach4, mb2ess issues
Regarding genuine... not sure
Re: Huanyang VFD, Mach4, mb2ess issues
Do the programing parameters start with a PD if so then it should be genuine, a photo of the terminals will also tell if it is as this is the most telling part

Re: Huanyang VFD, Mach4, mb2ess issues
Yes the programming all starts with PD, i think it is genuine
Re: Huanyang VFD, Mach4, mb2ess issues
So can you run the VFD Drive by it self and control the speed in Keypad mode
Mactec54
Yes, can run with keypad.
Re: Huanyang VFD, Mach4, mb2ess issues
Ok
So now you need to test the output from the Breakout Board on terminals AO and AL this needs to have a changing voltage 0-10v over the speed range so M3S12000 should give you close to 5v if not then you have settings in the control to setup to get this working once you have that working then connect it to the VFD Drive, then the drive Parameters and J1 jumper will have to change from manual control to remote control
Connect only after you have the 0-10v working
AO to VI
AL to ACM

So I stripped the wiring out, and started again... The lights on the mb2 are functioning normally, I have set of 02 pd02 both to 1..pd044 to 1.,. No action
Re: Huanyang VFD, Mach4, mb2ess issues
You have not said if the AO and AL connection / output is changing voltage, when you change the speed you have to check this with a meter at the Breakout Board lights don't mean that it is working correctly
Also check the NO1 and CM1 with a meter to see if it is opening and closing when you use a M3S12000 command in MDI mode
Leave PD044 at the default this does not need to be changed normally PD044=02
These are the VFD Parameters to be set to make it run by remote control
PD001=1
PD002=1
J1 Jumper Pins 1-2 / VI
PD070=0
PD072=400
PD073=120
You have not said what your Spindle / Motor spec's are so these Parameter settings may be incorrect for your Spindle / Motor
To check the VFD Drive you can add a jumper to FOR and DCM this will start the VFD Drive in Remote control if the Parameters are set correct this can only be a test using a Jumper
IF your VFD Drive Terminals have DCM then the Connection should be FOR and DCM
You have it connected to FOR and ACM it needs to be FOR and DCM

Ok, so finally got there, it was the DCM that i was missing! thanks for your help!
Now i need to control relays to activate solenoids. I have attached a relay 24v (mb2) - A1__ A2- y302 (MB2). I can see the light coming on/off but the relay is always energised??? Tried a few relays now and same result. Any ideas?
Re: Huanyang VFD, Mach4, mb2ess issues
Check that there is no voltage on the the input to the relay this will be controlled in the software
Check that you are not connected to a NC Relay, you need to connect to a NO Relay connection and when it powers on it will close and activate your solenoids

Have done so, I was going through the settings with just the relay coil connected, so no load on the switch side. I assumed the sink outputs block the current when not active, and act as a route to gnd/common when active. My thinking being that supply 24v to the coil and gnd to the sink output if that makes sense.. am I correct in thinking this is the right way to do it?
Re: Huanyang VFD, Mach4, mb2ess issues
Did you have a diode across the input if not you may have damaged the output from the Breakout Board some relays have these built in but if you are using a coil type relay and not a SSR then you need what is called a snubber to protect the outputs of your Breakout Board , what you need, a Schottky diode IN5819 or a IN4007 Schottky is better as it has a faster switching time
Depending on what your are switching your VFD Drive has at least 2 Relays that you can switch your relay, which you still want to protect with a Diode across the output from the VFD Drive
Check your Breakout Board Spec's they will list how you have to use the outputs to switch inductive loads, your Relay with a coil has an inductive load, most people don't use this type of Relay and use SSR ( Solid State Relay ) which are already protected
