Description:

After the picker places the leading edge of a picked plate just above the upper load ramp sensor, it moves Y back to queued_pos_y and then lowers the plate at slow speed by the max distance of queue_jog_z. This movement should be halted prematurely by the plate edge breaking the upper load ramp sensor if the plate is not too small. If it is too small then the queue_jog_z position will leave the upper load ramp sensor clear.

Type:

Default:

• 70000

Range:

• 0 to 500000 [mm]

Notes:

Once the jog movement is interupted, the firmware joggs it slightly further ( queue_jog2_z ) to guarantee that the upper load ramp sensor is covered. The vacuum is first checked to see if the picker has lost the plate. Then the upper sensor is checked to make sure it is covered. The plate size is calculated based on the known position of the Z-axis. Any discrepancy is flagged as an error.
