PLC Sets the consolidated orientation position (R7009) with the gear connect position and turns ON the orientation
(4)
command (Y189E) to set the positioning to the gear connect position.
PLC After confirming the orientation complete register (X188E), changes the physical gear to the turret gear.
(5)
PLC Sets the consolidated orientation position (R7009) with the selected tool indexing position and turns OFF the in-
(6)
dexing command (Y189C) to turn the turret to the selected tool position.
