Hey Fred,
rather this way:
As you see, the SSR works as normal from FC and DCM when VFD is in RUN state. If it turns to STOP, then FC cuts the power, but FC still goes to the timer module and triggers X1 by being cut (hope logical low triggers) and if the module works as we expect, the SSR is still fed over the rose wire so pump stays on for the delay time. The timer module always has DC+ to +24 V so is always fed.
Got to go to bed, have you seen it’s 03:34 h where we live 
Yes I saw the time but I’m on vacation. 
It must not be that, with this connection the drive does not start.
I double checked and tested all the connections with the multimeter. 
Hey Fred,
did you select Function 4:
Function F4:
Level-triggered mode: the relay is disconnected when powered on, and a high-level signal is given to the X1 interface, and the relay is closed immediately. After the X1 port signal disappears, the relay is still closed. When the pull-in time T1 arrives, the relay is disconnected.
PD052 must be set to 1 “Act when receiving RUN command”.
PS: Be aware of correct polarity of all components (+ and -) especially SSR control input!
“+24V” on VFD is DC+ and “DCM” is DC common, which means DC−.
“FB” is (VFD relay output) Common and “FC” is (VFD relay output) “Normally open (NO)”.
PD052 must be set to 1 “Act when receiving RUN command”.
(The reference I use is HY01D523B-VFD-Manual.pdf)
Select Function 4 on the module.
The SSR should switch your pump on at least, as it is wired the usual way. On your first image above, you reversed polarity on the relay!
If you checked everything that I mentioned, does the pump go on if you select RUN the VFD?
If so, but the pump does not stay on with a delay after returning to STOP, then you can try the following: Put the VFD in STOP mode, and bridge X1 and DC+ of the module. Does the pump on the SSR then go on?
It’s the whole vdf that won’t start.
I followed the diagram to the letter, I just have a doubt with the ssr, it is difficult to access.
Yesterday I set the function to f4 it should be saved.
My P052 is set to 2 “zero speed”.
After eating I will check the ssr wiring.
Disconnect everything so that the vfd starts (this is the case with my starting connection or nothing) to set the P052 to 2.
I’ll let you know.
What do you mean? Does it not go on, or does the spindle not run?
This is wrong. It would mean the pump would go on when the spindle is stopped. I think of course you want your coolant pump to run when VFD is in RUN mode As I said, it needs to be set to 1 “Act when VFD is in RUN command”
Did you check the wrong polarity of SSR in your first image?
What I mean is that when I plug like in the diagram, the vdf does not turn on.
It’s not wrong P052 is on 2 on my vfd and it works, the pump starts and goes out with the spindle.
No I haven’t checked the pèolarity yet, I’m going now
Hey Fred,
can you measure whether the 24 V voltage breaks down if you use the diagram and the VFD does not turn on. It may be possible that the 24 V from VFD is not capable enough for the module. Unfortunately the Huanyang manual gives no current rating for this 24 V output.
This makes no sense to me. “02” on PD052 (FA/FB/FC function) (according to manual) does mean:
“02: Zero Speed: The contact will act when the output frequency of the inverter is less than its starting frequency.”
Starting frequency is PD027, Range is 0.1 – 10 Hz, Units: 0.1 Hz, Factory setting is 0.5 Hz.
So this would mean the contact is said to act when the output frequency is under 0.5 Hz, which means, the spindle is practically running at zero speed.
Or did you connect to “Normally closed” (FA) output? This would explain inverse behaviour.
Or instead of +24V do you have DCM connected to FB?
So the ssr wiring is good. The - on dcm and the + on fc.
For p052 if I set to 1, the pump starts instantly even if the spindle is stopped
Since nothing lights up, I think I would have 0 v. But I want to measure
Did you connect to “Normally closed” (FA) output instead of FC? This would explain inverse behaviour.
Or instead of +24V do you have DCM connected to FB?
There also is the possibility that the Huanyang Manual is not correct. I have read multiple reports of things changed by manufacturer without notice (on Huanyang VFDs).
What we got to know is why the VFD does not turn on.
or the terminal block does not correspond to the internal wiring
Why fa/fc/fb and not fa/fb/fc ?
Wiring on your image looks correct and corresponds to manual.
Who knows?
What about +24 V voltage when you have connected the wiring above and VFD does not turn on? Can you set your multimeter to DC and measure whether the voltage breaks down?
I am to reconnect the trm01 to measure.
For the multimeter I put it on 200, one clip on 24v and the other on dcm?
For measuring the +24V to DCM, “DC” ( ⎓ ) setting is important on the multimeter, not “AC” ( ~ ).
What if you disconnect X1 from FC?
And what if you disconnect the DC+ of module from +24 V of VFD, then the VFDs goes on? If so, then I would test the module with a separate 24 V power supply.
I bought this one for my VFD control cabinet, but this one will also do. Choose some power reserve if you think you may add other components later like a safety relay which is 24 V too.
