Hi, I don’t currently have a VFD/Spindle. With a router you have the physical on/off switch to make sure power doesn’t turn on when you are changing the bit, even if your router is controlled by the Onefinity controller (pin 15). What’s the equivalent with a HUANYANG HY-Series VFD and spindle? H…

Thanks. I saw those buttons (and that response before) and thought of that but it still seemed like it was under electronic control vs a physical power cutoff. I.e. If you hit stop on that and put your wrench on the collect, there’s still a possibility that software could switch it back to run …

Hey Atroz, what you are saying, could it be that if the authors of IEC 60204-1 , which is an industry standard used in the entire world’s machinery industry for safety of machinery, sell you a “Safe Torque Off (STO)” as not safe? A noise or bit flip is not likely to be that smart that it acts as a …

I guess I’m a bit old school where I was taught to disconnect the power before changing bits/blades. This trusting the software thing leaves me a bit uneasy but you are right, it is the standard. Thanks.

Hey Atroz, on Omron MX2 / Hitachi WJ200 and some other VFDs for industry, you can additionally use their emergency circuit capability . These industry VFDs have ISO 13849-1 Safety Inputs with which you can put the VFD into an emergency stopped mode. This will prevent the spindle to run even if you p…

PS: Quickly searched it for you :slight_smile:: Emergency Stop circuit on VFD ← Here it is Risks from rotating parts and flying debris : [image] Power Switch For Huanyang 2.2KW Inverter … the spindle manual also says: 5.2 Risks from rotating parts and flying debris Use machine encapsul…

Thanks. I do intend to add an emergency switch (have one in my amazon cart) and I do have my CNC machine in an enclosure. No switch on the door though.

Hey Atroz, if you search for “Emergency Stop” in the forum, you will notice that there are two very different kinds of Emergency Stop or Poweroff. For the one which we discussed above, which is described here and which means to prevent the spindle to run in case you open the enclosure door or durin…

Yes, I’m talking about the first type being in my cart. A push button that latches to unlock, connects in to the “estop”. The Onefinity one is also easily accessed and I’ll put another on the VFD. 2 switches because of 2 circuits (110V and 220V). I’m the only user of the machine.

Hey Atroz, just an addition, I think you already know that – at least when I looked at the circuit the last time – the big red/yellow button on top of the Onefinity Controller case is NOT wired to enter the smart “ estopped mode ” which will make sure the spindle is also stopped (or the “tool-enable”…
