ATC OPERATION
5.1 CAROUSEL TYPE ATC OPERATION
5.11 Safety Rules -- READ BEFORE OPERATING ATC
CAUTION! Always follow all Lock Out Tag Out procedures before performing any maintenance
• Due to the complexity and timing of the ATC, it should only be operated with the M6 command.
• Never interrupt the tool changer in the middle of cycle, wait for it to complete the tool change.
• The carousel motor is a 3-phase motor and must be phased correctly for proper direction. The machine is
phased properly at the factory before shipment, so if the carousel rotates in the wrong direction, switch any two
incoming power wires at the disconnect. Make sure the main power breaker is off!
• M58 moves carousel position CW one position, M59 moves carousel position CCW one position.
• If the T code is programmed on the same line as the M6 command, make sure the M6 is before the T code
(example: M6T4).
