Description:

The "cal" command is used for vacuum calibration and bay position calibration.

"Cal bay" may be used on a machine during initial start up. The user must ensure that picker Z and Y are in a safe position to move home. The command will move the picker home, then move the picker in the Y direction to resrch for the bay tabs and count the number of bays untill the away sensor is tripped. I sets up nvs "al bays", "bay <#> loc", and "aldrv Y limit" Note these nve settings are not saved.

"cal uvac" and "cal pvac" work similarly, they position the picker ucup/pcups in a convenient place, turn on the vacuum and take a vacuum reading with the cups exposed. Then the user is required to seal all but one cup with a piece of plate, and another reading is taken, then the user is required to seal all cups with a piece of plate and the final reading is taken. Thresholds pvt/uvt and pvrt/uvrt are calculated and saved and the picker returned to home.

Applies To:

• Platesetter_3244

Syntax:

Notes:

The position of the table during cal is designed to be the same as that when the uvt threshold is used, namely the unload position.

Only in f/w 2.24 and newer.
