I'm a total noob at electronics, but my employer has asked me to try to program a replacement VFD on our industrial stone-cutting saw. Everything works on it now, but I need to figure out how to implement the jog mode that was on the old vfd before it got fried.
As best as I can remember, when we flipped this switch on the control panel, the motor would jog for about two seconds, and then pause for about 20 seconds, then jog again. That would continue automatically until we switched back to the normal mode. There is another dial on the panel that would control the motor speed both in the normal mode and during the two second pulse in the "jog" mode.
Any idea how to implement this back into the new VFD? Unfortunately the old one is totally fried, so I have no point of reference to work from.
As best as i can tell now, that wiring inside was done in a rather unorthodox fashion... there doesn't really seem to be a set of parameters in the advanced manual that really correspond to how it's set up.
I know this is all super-vague, but feel free to ask for any details that I provide for you.
Thanks in advance!
The VFD is a Commander SK from Nidec, and is identical to the original. PN: 0472-0001-11
