3.1 Software limits
When you select <3/3/B1 ADJUST TARGET> - “Soft Limit”, the Software
Limit screen opens as shown below. You can check and adjust here the
software limit parameters to determine the axis movement range and initial
position parameters used as a reference point for axis movement.
These parameters must be set correctly to maintain accurate machine
movement and component mounting.

minus sign
Position at which all the A/B tables, carry-in conveyor and
carry-out conveyor are aligned straight during PCB transfer
Angle at which the nozzle holder leaf springs are parallel to
the X-axis arm.
Position at which the A-table main stopper is in contact
with the center transfer hook
This is the T-axis stroke for transferring PCBs.
Fixed to 395mm (standard machine).

CAUTION
The software limits, initial positions and initial movement settings are preset at the
factory prior to shipping. It is unlikely that you will need to readjust them. If readjust-
ment is required, make correct settings while referring to the above points. For more
details, please contact YAMAHA sales office or dealer.
