have you got more informations? Is the barfeeder running before or it's a new installation? Can you jog the barfeeder with the wheel in the handlejog?(V-axis).
Maybe it's only a problem with the cableconnection to the SL-10 or a wrong parameter.
Handle jog the V-axis until he is up to the reference position. enter G105 Q1 in the MDI and push cycle start.
It's possible to run the V-Axis? Do the barfeeder try to push out a bar?
