Fagor nc-200 pb Installation Instruction

Method  recommended in low range drive systems:  unipolar drive [PAR45(1)=0],
proportional valves, etc.

PAR27 sets the distance before the end point where the analog voltage is
canceled. On drive systems with good braking response, the drive may be kept
active delaying the releasing of the enable relay. Just connect a capacitor in
parallel with the relay. Forcing PAR27 with small values may result in a sudden
braking and a later release when the axis reaches the end point.

If the axis is forced to get out of the in-position zone, the enable signal and the
analog voltage for the slow speed are activated to restore the programmed
coordinate.

Method especially developed for the Y axis on "C" type machines with direct
control of the ram or table position.
