2.4.4 Y AXIS HOME SEARCH. MODEL "C"
An up-stroke or down-stroke model "C" has a linear encoder and controls the
actual (real) position of the ram using foot switches. It usually has travel limit
switches.
If PAR00 bit 6 = 0, has been set for a linear encoder with a regular reference
mark (without distance-coded reference marks), the homing procedure is the
same as described in section 2.4.2 (a)
If PAR00 bit 6 = 1 has been set for a linear encoder with distance-coded reference
marks.
The homing sequence is as follows
·
Set the NC in Home search mode by pressing
.
The
led will turn on.
·
Select the
axis. The unit will display the text "START".
·
Press
.
The axis moves upwards in the positive direction until detecting two consecutive
reference marks (I0's) and it displays the reference value set at PAR10.
PAR10 = D - O +
ε
Where D = Distance between the support bases between the punch and the die.
O = Offset value indicated on the label of the linear encoder
ε
