Need assistance with electric enclosure please (CSMIO/AC Contactor issue)

[JAZZCNC]

also I would like to you utilise the software to enable a power on signal

If your refereing to HV enable then it's not really very suited to this application because it will Kill power to VFD every time you put Mach in reset. Which will be often. This constant stop starting isn't good for the Vfd and will damage it over time.
Also you won't be able to start cutting straight away after a reset and will need to wait for VFD to power up fully which could be pain.

If you really do want the VFD turned off then I would have the VFD tied to E-stop but keep it separate from HV enable. Just have HV enable control the drives PSU and the Spindle RUN Command.
This way when Mach3 is in Reset mode then the VFD stays on but can't started until mach is reset. At which point HV enable turns on the drives and allows spindle RUN signal to reach VFD when needed.

Think of it has two separate systems working together. E-stop is hardwired and kills everything, HV enable just kills Drives and Run etc but only when mach is in Reset.
There are many times you'll want some things powered while Mach is in Reset mode. Ie Vacume but at same time your not in E-stop condition.

thank you guys for the insight and preventing me from making a mistake, I guess the VFD manual confused me because it has some notes about when using a contactor. so in this case is there use for a contactor (for the VFD) at all if controlled through a constant turn on signal?

appreciate your input on following related subject as well: at the moment the planned way to start/stop the spindle is through input signal coming from CSMIO (the usual way) , in case of problems and I hit E-Stop, naturally CSMIO will disconnect that signal and spindle will stop normally.

is that sufficient or should I utilise the other input ports of my VFD, it has a total of 8 ports to accept commands from a controller.

they are as following:
0 - No Effect
1 - first multi speed ( references a table in the manual )
2 - second multi speed ( references a table in the manual )
3 - third multi speed ( references a table in the manual )
4 - frequency rises
5 - frequency decreases
6 - forward jog
7 - reverse jog
8 - forward ( this is what I used before and works fine and is enough to start/stop it )
9 - reversal
10 - forward trigger
11 - reverse trigger
12 - stop
13 - freely shutdown
14 - forced shutdown
15 - forced inversal
16 - counter is cleared
17 - counter input
18 - program run reset
19 - external fault
20 - external reset
21 - accelerate and decelerate - time choosing first ( references a table in the manual )
22 - accelerate and decelerate - time choosing second ( references a table in the manual )
23 - accelerate and decelerate pause
24 - force ACI passage effective


I don't understand most of them but its a direct copy-paste from the manual.

so is it worth doing a setup where one of those functions is triggered during E-Stop? maybe the stop or external fault? hehe feels like overthinking things
