Tool changer logic

After all the axis of the machine have been homed as per the homing sequence the tool changer logic will read the encoder data from Turret to get the current tool in position.

If a valid tool number is received then the current tool number is updated on the controller else an ERROR message is displayed on the screen telling the user that the signals from Turret were not correct.

CAUTION: In MASSO G2, tool numbers start from Tool No. 0. When a command is given to load Tool No. 0, on the Pragati Turret Tool No. 1 is loaded. When tool load command is given for Tool No. 7, on the Pragati Turret Tool No. 8 is loaded. This has changed for Software version 4.02.77b and Higher. Please see the section on Tool numbering at the bottom of the page.
