I’m in the middle of setting up a newly acquired Delta 34-806 3 phase Unisaw. I’ve purchased a Teco JNEV-203-H1 VFD based upon a post I saw on this forum. As I only have single phase power in my shop, I needed a way to supply 3 phase power. The VFD seems to be the ticket.
I believe I understand all the connections needed to supply AC power and the need to directly connect to the motor from the VFD, but I have no experience with the low voltage switching side of things. I could really use some help / a wiring diagram on how to remotely control the saw with the on /off switch. I realize I’m going to need to set the dip switches for external control and to then do some setup / programming for what each lug on the terminal block does. I just don’t understand which ones to use and what each needs to be programmed to do. I have very simple needs…start the saw with the on button, ramp up to full speed in 3-5 seconds, stop the saw when the off button is pressed and allow spin down in 3-5 seconds. No additional breaking, emergency stop, etc.
The switch I have is a two button setup (on/off) that has a common between them (3-wire to the switch and ground to the box). It appears that each button has a separate power lead. My assumption is that each switch is simply completing a circuit and switching a relay. i.e. on / off, but I am lost after that Any assistance on how to setup and control this saw with the remote on/off switch from the VFD would be greatly appreciated.
Thanks in advance,
