Fagor nc-200 pb 安装指导

In this mode, the initial values are preset in a fixed reference position.
If PAR14.4 = 1 on any axis, home search is mandatory on that axis every time
the machine is turned on.

This unit starts in 

  mode.

To quit this mode without homing, press 

 and key in the access/exit code:

If PAR14.4 = 0, home search is only required on machine setup. At the beginning,
the software limits PAR12 and PAR13 should be opened to their maximum
values to prevent this NC from forcing uncontrolled movements in order to
position the axes within these travel limits.

Should this happen by mistake, the movement may be stopped by pressing  

.

Being PAR14.1 = 1 (Floating home search), if while in this state you press 

[access code], the affected axis will show the value: PAR12 + PAR26 as initial

value. When pressing the relevant key 

 , 

 , it will suggest the PAR10 value

by default with an option to select any other as described in later chapters.

PAR14 establishes how the machine reference (home) search is to be carried out.

All models perform this home search in the positive direction.

The X axis usually has a travel limit switch: PAR 14 bit 1 = 0 and a rotary encoder.

The home searching sequence is as follows:

·

Set the NC in Home search mode by pressing 

  .

The 

 led will turn on.

If the home search for any of the axes is defined as "floating"

(P14.1 = 1), it requests the password (719200) after pressing 

 .

·

Select the 

  axis. The unit will display the text "START".

·

Press 

 .

The Axis moves in the positive direction, backwards, in rapid until reaching the
positive travel limit switch.

Once the switch is pressed, it returns at slow speed until the reference mark (I0)
of the rotary encoder is detected. At that point, this unit displays the value set
at PAR10 (that will correspond to the real value from the center of the die to the
support side of the X axis). See section 2.4.5
