Some body that can help me with next problem
I have a DC-300 drive on a graphic machine with tachometer speed feedback but now the tachometer is wrong and I don´t have a spare tachometer for replace it, then I need operate the machine with DC-300 armature voltage feedback, without tachometer, the problem is that I don´t know how to do it.
I think that any soft jumpers and/or hard jumpers must be modified but I don´t know the address and new value for the soft jumpers and the positión and number for the hard jumpers.
Thanks in advance
