Connecting 407 to new VFD
« on: January 13, 2017, 02:09:50 AM »
Hi all

I had  spindle speed control via a 407 connected to a Holip brand VFD. VFD died and I bought a Huanyang HY02D223B to replace it. Control port names are completely different so I need some help with connecting back up. Its a router so I only need forward rotation and Mach4 command of rpm.

Previously wired as:  Aref -> +10v,  Aout -> VI,  Agnd -> ACM,  Run -> For,   Com-> Dcm.

Terminals available on the new VFD:
12V out
5V out
5V in
10V in
20mA in
5V F out
GND
FWD
REV
RST
D0+
D1-
D2 JOG
Lk
Lb
Lz

So what goes where??

TIA

Mitch

Mitch,

Your list of terminals does not match the documentation that we have
for this model VFD. Can you supply a copy of your manual or a link to
it on the web?

PS - I am leaving for the Cabin Fever Expo show and may not be able
to respond until I get back on Monday.

Thanks Steve.

Page from the manual that came with the drive is attached. Connector on VFD is the same as this.

Cheers

Mitch

Sorry to be late with this reply. I was away at the Cabin Fever Expo
show running a PMDX booth there, and I am still catching up with
things upon my return.

This looks like one of the newer low cost Chinese VFD units. I have
not found clear descriptions of how their control interfaces work, so
we have to make some assumptions.

I looks like the VFD will accept analog 5 volts, analog 10 volts, or
current loop control. The 5 volt input may work, but will be less
precise than the 10 volt input, therefore I will describe 10 volt
operation.

Aref  from   12VOUT on VFD
                  It is OK to put 12 volts on the 407 and even on the
                  10VIN of the VFD, but we suggest adjusting the pot
                  on the 407 so that the maximum output is 10 volts
                  so the the speed is more accurately calibrated.

Aout to       10VIN on VFD

Agnd to       GND on VFD, there will multiple connections to GND on the VFD

RUN  to       FWD on VFD

COM to        GND on VFD

It is also possible to control direction by passing the RUN signal through
a relay if you have a SmartBOB that has the relay. The RUN signal would
go to the COM of the Relay. The N/C of the relay would connect to the
FWD on the VFD. The N/O of the relay would connect to the REV on the VFD.
You must also configure the Reverse signal in Mach4 to control the relay.

Hi Steve

Thanks for that.... it's working like a charm.

The assistance from Bob and yourself is much appreciated.
