Some time back, I bought a Jaguar Cub inverter. Model CUB3A.

I have that connected up to drive a three phase motor on my lathe. All
works just fine.

Now I want to make an external control box for it but I can't seem to
work out some of the details.

FWD/REV and speed are simple enough but I am not sure how to get the
start/stop connected. There is a stop input available on termnal X2 but
as soon as that is released, the motor will start again. I would like to
add an emergency stop function that latches on, like an NVR switch.

Has anyone got, or can point me to, wiring details for an external box
for this inverter?

Thanks

Suggest you take a look at the programming and connection options in
the manual. You need to look for "three wire control". Programmed in
this way the system should run as I am sure you expect.

I have had a good search of the manual and can only find one fleeting
reference to 3-wire control. After reading it I am no wiser. It says
that one of the control inputs can be configured as a HOLD function. I
quote:

--8<----
Select 3-wire operation command--(HLD) (Function code data = 6)
Digital input signal (HLD) may self-hold the forward (FWD)/reverse (REV)
run commands given at the external signal input terminals to enable
3-wire inverter operation.
Shorting the circuit between the (HLD)-assigned terminal and terminal
[CM] will self-hold the (FWD) or (REV) command. Opening the circuit will
release the hold.
--8<----

Searching through Google, now I know the right term, has not really
helped. There is stuff using relays. (Who on earth decided to use a
capacitor symbol for relay contacts?).

I found your post here on June 5th and what you describe is exactly what
I want.

Can you elaborate on your wiring setup?

I have sent a mail direct with circuits, however having now read the
manual (what a pain in the A****!) you will need to do the following

1 Set the jumper to "Source"
2 Assign 1006 to E01 (this sets the X1 terminal as the HLD for three
wire)
3 Set F02 to 1 (Sets external control with no action from keypad
buttons)
4 Using my circuit rename the connections as follows
My Terminal Cub Terminal
STOP X1
START FWD
REVERSE REV
COMMON PLC

Thats how I read it from the PDF but may well be incorrect somewhere.
Assuming that I have not missed something from a quick read, I would
lash up the control with fwd rev and stop buttons first to prove it
out before going to my circuit (assuming my option is what you want).
You do not even need buttons link PLC to X1 with a short flying wire
you can dab to Fwd or Rev Disconnect X1 to stop.

PLC-----|/|--------| |----FWD

----| |----REV

-----------X1

|/| = Normally closed momentary contact (Stop button)
| | = Normally open momentary contact

Ok they look like capacitors but you do better in ASCII art ;-)

Suggest that you actually set motor direction by swapping 2 motor
wires if FWD connection runs reverse for your application.
Best of luck
