2.4.2 Y AXIS REFERENCE (HOME) SEARCH. MODELS A AND A1
a- If the machine has travel limit switches, the home search procedure is the
same as the one described for the X axis; but it is only enabled if I13 = 1,
ram at top dead position.
b- If the machine does NOT have travel limit switches (which is very common
on down stroke models), set PAR14 bit 1 = 1 to indicate that the reference
position is floating.
The homing sequence is as follows:
·
In MANUAL mode, move the Y axis in the Y+ direction to make sure that
the backlash is properly compensated for.
If P17 = 1, the Y- movement will be affected by the unidirectional approach
and will return in the Y+ direction.
·
Press the "BEND" footswitch until the ram reaches its final position. Output
O27 is active ("A" model) to enable the footswitch.
·
Measure the distance between
the support bases of the punch and die.
This distance will be the Y
ref
to be preset.
·
Press
. The
led will turn on. Enter the password (719200).
This unit displays the real position and the axis remains on stand by.
·
Select the
axis, (by default, it suggests the PAR10 value) and preset the
reference value Y
ref
and press
to assume it. It displays the coordinate
( Y = Y
ref
- H
punch
- H
die
) compensating the height of the tools that are active.
