DEVIATION

Deviation is a function gated by the relative button; it is activated when the led is on and it  makes the axis 
position increase according to the value programmed in the machine constants, when the relative input is 
closed.
The increase occurs after the time, programmed in the machine constants, has passed.
During this movement the O.K. position is closed.
The   coming   back   to   the   previous   position   occurs   when   the   cycle-increase   input,   which   has   priority  on 
deviation, closes; in fact it's possible to come back to the value even if the deviation movement has not 
finished; during this movement of return O.K. position is open. Each axis may be equipped with this input.

RESET

Each time this input is closed, the reset value, memorized on the machine constants, is stored on the counter 
and this value is the new position of the controlled axis. This happens only if the output of 0 of the encoder is 
not connected to the INPUT 0. Each axis may be equipped with this input.

0  ENCODER INPUT

Each   time   this  input   is  gated   from   the  encoder   output,  the   value   of   reset     memorized   on  the   machine 
constants is stored on the counter and this is the new position of the controlled axis. This happens only if the 
contact on RESET input is closed.
Each axis may be equipped with this input.
