Dave,
what wiring did your machine have? Mine is the 'Safety Electric'
wiring. I'm still trying to understand it. I'm a physicist, this
stuff is not totally alien to me, I just don't quite understand little
boxes that say 'low voltage release'. Trying to understand items like
c1 with terminals a/b and 13/14
If I wire the motor directly to the VFD, this whole circuit won't be
working, right? Since I won't have high voltage on it? My VFD wants
a low volt. signal though passed through an EMO switch... I am not
piecing it all together. I know I can get the functionality, I know I
can jumper that signal at the VFD side. Need to stare at it more I guess
There is a diagram in the pictures section, and a text file in the
files section. Figuring out the pinout on the barrel switch can be a
pain, and they are not all wired the same. It would be easier to
bypass it all, but you must insure that motor leads U2, V2, & W2 are
disconnected from the barrel switch. Otherwise, the position of your
switch can cause the motor to run in high speed.
Most VFD's provide the low voltage control circuit. I'm not familiar
with the little Rockwell drives, but it's often labelled Vcmn as it
uses the negative side. If you don't have a manual, there may be one
on the Allen Bradley website.
