Fagor nc-200 pb Instruccion De Instalación

A. Controlling only the final position of the bend.

The foot switches and the hydraulic circuit are not controlled by this NC. The
intermediate positions of the ram are detected by electrical microswitches.

A1. Same as model "A" with footswitch treatment and outputs for governing the

hidraulic valves for the 4 EXECUTION modes.

The rapid approach feed is not managed.

Especially indicated  for conventional down-stroke machines.

B. Same as model "A" with a linear encoder or potentiometric scale for decoding

the intermediate ram or bed positions affecting the bending approach speed and
depth:

With outputs to relays or to a PLC:

STOP - Top dead point overrun

S9

Fast ram approach.

S29

Slow speed controlled by the footswitches.

S28

Ram retraction.

With internal processing: (without external output).

·

Going through "Y=sheet thickness" position to withdraw the X axis.

·

Bend position reached to start bending timing on upstroke models that do
not have a presostat.

C- Control of the actual ram/bed position.

With internal processing of all the intermediate positions.

The footswitches control directly the position of the bending tool, Y axis.
