Re: [CAD_CAM_EDM_DRO] toshiba vfd

Jon,
Sorry it took so long to reply to your suggestion. I
tried the jog function but I must have done something
wrong. I wound up using the pre programmed speed
function. I am using opto 22 relays and I had to go to
a reed type relay to switch to the speed 1. I tried
the same setup with the jog but I could not get it to
work. I have had help from toshiba and the pre
programmed speed was their idea.Thanks for the reply.
