Hi everybody,
I have a spin machine, imagine a potting wheel except it spins a flat canvas and then you pour paint onto it.
It has a VFD to control the speed.
My electrician is having a little trouble working out how to brake the spinning wheel once i slow it down or press stop.
As it happens now - I run it at about 1100 rpms and then when you switch it off, the VFD seems to brake it to about half that quite quickly and then it "disengages" and the wheel "freewheels" until it stops completely. (As it has a metal plate on it, there is a little weight which encourages the motor to keep spinning.)
It takes a long time to come to a complete stop and I want to make it stop a lot quicker.
I do a lot of stop/starting with my customers and the wait time is too long...
Anybody out there able to solve this?
Thanks
Ben
