2.1.12 Vacuum Timing Offset

When the "Head [1/2]" tab is pressed in the "Device Offset" tab sheet and the

"Vacuum Timing" tab is selected, the following tab sheet appears.

[1] OFF [sec]

The speciﬁed parameter is used to adjust the timing to turn the vacuum

off while the NL-axis is descending for component placement.

When "+0.000" is speciﬁed in the "OFF" text box, the vacuum is turned

off when the NL-axis has reached 10 ms away from the bottom arrival

point.

Base on the point 10 ms away from the NL-axis bottom arrival point,

a plus value in the "OFF" text box means that the timing to turn off the

vacuum will be delayed. A minus value means that the timing will be

quickened.

[2] ON [sec]

The speciﬁed parameter is used to adjust the timing to turn the vacuum

on while the NL-axis is descending for component pick.

When "+0.000" is speciﬁed in the "ON" text box, the vacuum is turned

on when the NL-axis has reached 10 ms away from the bottom arrival

point.

Base on the point 10 ms away from the NL-axis bottom arrival point,

a plus value in the "ON" text box means that the timing to turn on the

vacuum will be delayed. A

minus value means that the timing will be

quickened.

[3] Pu retention time [sec]

Set a parameter to specify the time when the nozzle must be stopped at

the lower limit for all component picks.

Note

Use this function when components cannot be picked up in stable condition

due to the inﬂuence of the component pickup surface and the compatibility

with the selected nozzle.

[4] Pl retention time [sec]

Set a parameter to specify the time when the nozzle must be stopped at

the lower limit for placement of all components.
