Toshiba VF-S11 VFD for Lathe Spindle - Problems with setup/wiring to 7i76e

Hello Guys, my lathe project is almost finished, but since couple of days i am having problems with the VFD setup.

Please do not get me wrong, but i have tried couple different wiring setups, which i think makes no sense to describe them all here but only 2 of them, because i would need to try all those setups again and describe exactly what is happening, so i would really wish you could help me out by checking the TOSHIBA VF-S11 manual: inverterdrive.com/file/toshiba-tosvert-vf-s11-manual

I am using a Mesa 7i76E.

The problem is almost same no matter what wiring setup i am using : On the VFD i can use 2 logics by switching a switch: Source (POSITIVE / Common : P24) and Sink (NEGATIVE / Common: CC)I will give you one example of the wiring setup i tried and tell you what is happening:

Logic: SINK (common: CC terminal pin)
Wiring:
10v to Pin 3
VIA to pin 2
CC to Pin 1
F to Pin 6
R to Pin 8
CC to Pins 7 and 5

What is happening: When starting the spindle on gmoccapy by clicking on the CW Spindle On button (its a lathe so the spindle should turn Counter Clock wise) nothing happens, when clicking the Gmoccapy CCW Button the motor turns, but it goes to max rpm

Pictures of wiring setup, HAL and INI setup (sorry that i did not attach the hal file and ini file as i should, but i have some strange network problems on my lathe pc)


Next try: Source (Positive) Logic (Common: P24)
Wiring:
10v to Pin 3
VIA to pin 2
CC to Pin 1
F to Pin 6
R to Pin 8
P24 to Pins 5 or Pin7, because when both are connect to P24 then nothing happends. If i put P24 to Pin7 instead of Pin5 then the Motor runs in the opposite direction.

The Problem with this wiring: When clicking on the CW spindle On button in Gmoccapy then the spindle runs (almost, because its not scaled perfectly) with the correct speed and the correct direction for my lathe. When clicking on the CCW button, the spindle turns in the same direction and the motor turns to max speed (at 60hz)
Pictures of the wiring setup:

Actually i wanted to use a RS485 to USB adapter to control the spindle speed and direction, but it seems i need some kind of special board for that, so i have no other option than to use the 0-10V analog control method.

I really hope you can help me out again with that problem.

Thanks in advance!

At least part of the problem is that the hal file is using signed spindle speed
command (spindle-vel-cmd-rpm) instead of a absolute spindle speed
(spindle-vel-cmd-rpm-abs) to set the analog output (which is unsigned)

Thanks PCW, but i dont what you actually mean and also i dont know how that should help me with the vfd problem (cw and ccw direction).

I do not see any command that is unsigned, but maybe i do understand something wrong.

Could you please tell me what i should do to solve the problem you are talking about

EDIT: I changed the line: "net spindle-vel-cmd-rpm" to "net spindle-vel-cmd-rpm-abs" for the "pid.s.command"
Now the spindle turns with the same speed , but of course still it turns only in one direction.

The 7I76E analog output is unsigned, but the hal file is connecting it to
a signed rpm value. this will not give the proper analog output for negative
spindle speeds. basically it means that

net spindle-vel-cmd-rpm pid.s.command

needs to be changed to

net spindle-vel-cmd-rpm-abs pid.s.command

Note that thiis is a necessary but probably not complete fix
and you need to get the direction control working also

Thanks, jus edited my last post, because i changed that line already and now the spindle turns wirth the same speed when clicking on CCW and CW button, but still the motor turns only in one direction, which of course does not suprise me.
There should be some setting in the VFD i think, but i checked the manual already many times and couldnt find anything interesting.

Most VFDs have a run/direction option (instead of FWD/REV) but I don't see that for this
particular drive so I suspect you will have to use some 7I76E field outputs to drive FWD and REV

Thanks PCW.
I understand what you mean.

I added this 2 lines:
net spindle-cw hm2_7i76e.0.7i76.0.0.output-04
net spindle-ccw hm2_7i76e.0.7i76.0.0.output-05
(outlined the spindir line)

No i am really confused and do not understand what is going on:
I opened linux after editing the HAL and tested the cw ccw buttons but nothing happend.
Then i shorted CC to F with a wire and somehow both direction worked, so i thought i got it done by your help and wanted to make a bridge between CC and F so that i dont need to hold that wire. When i put the wires back only one direction worked.
Not sure what i have done or why it had worked, but thats my current situation.
PS: On the TB4 i took all wires off and only kept the 3 wires for 0V, 10V and spinout.

You would need to connect CC to 7I76E field common and 7I76E
output 4 to F and output 5 to R (Toshiba manual page B10 right picture)
note the "Slide switch SW1:PLC"

Thank you PCW for taking your time to help me out.

I tried exactly what you wrote, but unfortunately nothing happends on the motor.

I have took field common from the orange field terminal pin NC (ther two pins next to 0v pin)

did you verify that VFD F and R inputs have 24V relative to their CC pin
when the spindle is on? (F or R depending on direction)
