Hi all,
Looking for guidance on installing an external two button on/off switch with my VFD stop/start switch to operate themTECO 510 VFD I installed on my three phase pedestal grinder. The VFD works fine, but does not respond to stop/start commands from the switch. So I don't know if my wiring configuration is wrong (highly probable) or I am missing some secret set up parameter that TECO doesn't want me to know about-or both.
Can anybody suggest what I should correct or do differently?
Here is the switch and the wiring configuration I set up. The black lead is connected to the S1 terminal (4th terminal) on the TECO 510, and the 'power' side of the switch. The red lead connects to comm and the 'line' side of the switch. This gives me a 24v reading on my ohm meter across the terminals when I press the start button, and 0.0 v D.C. When I depress the stop button. But no response from the VFD.
I set the parameters according to the manual for a two button on/off switch as follows:
00-04 [1]
03-00 [0]
03-01 [1]
My second basic question is - how should I read this wiring diagram properl? It the TECO manual shows the stop and start terminal leads all apparently jumpered together - into one continuous circuit leading from the S1 terminal in a loop through the switch, back into the 'com' terminal on the VFD?
This doesn't make any sense, as I am confused by what COM actually is/does.
Thanks for any help you can offer.
