9.4.2.2 Placement: Z-Axis Upwards with "Slow Start"
Benefits of Special Mode "Slow Start"
The CO stays on the board even if the soldering paste has a low holding force.
From LRU/LRL 503 and SIPLACE Pro, this
placement type can "only" be programmed in the
CS "for SR/MC 503 stations and higher".
LB down switches:
End position signal for downwards and valve
positioning drive ON for air kiss
Measurement of air kiss pressure during
placement
Start signal for upwards movement
Z-axis starts:
Positioning Z-axis up with reduced starting
speed for the first 44 digits
LB up switches:
Electromagnetic valve for air kiss OFF
Reset LB down signal
Start signal for gantry axes
Z-axis end position signal (Z-axis at 0 position):
Enables vacuum query: "segment airtight?"
after placement (SR/MC503)
Start signal for star axis
NOTE:
However, this option makes the placement procedure around 20 ms longer than
the standard placement procedure.
