When I press stop, my VFD remains in standby (Can't find any settings to change this). How much current does a VFD typically draw in standby? I guess I could wire in a switch but seems like a pain to have to press stop AND flip a switch when you are done for the day.
Very little. I have 3 that are on continuously. My power usage in my shop as I write this is 554 watts. That includes 4 VFDs, 3 computers, 3 CNC control systems, lathe DRO, various battery chargers, and a refrigerator (which just happens to be running at the moment). The VFDs are a very small fraction of that.
On the other hand, just shutting down my CNC lathe requires more than just flipping one switch:
In this case the spindle VFD is shut down at the end of the day.
Press E-stop, shuts down servo drives and puts VFD into E-stop mode
Press Control Power Off, shuts down hydraulic pump and a couple cooling fans, removes power from a couple other systems
Flip the Main Cabinet Disconnect to Off, removes main power to the lathe, turns off a couple more fans, but leaves the computer and control system up
Press E-stop on the RPC, shuts down the RPC, leaves the RPC startup VFD, and control system hot.
So flipping an extra switch at the end of the day isn't terrible.
